10 Best Crustdata Alternatives For B2B Data Enrichment in 2026

Major Takeaways

Why do teams look for a Crustdata alternative? Almost never because of the data. Crustdata’s accuracy and coverage are strong. Teams leave over cost and how it’s sold: there’s no self-serve plan and no free tier, so trialling the API means booking a sales call and being qualified first, and the resulting price reflects that sales-led motion.

How do these alternatives actually compare on price? Not by cost per credit, which is misleading. A credit buys one work email at Limadata and ten at CompanyEnrich. Normalized to the same workload – 10,000 verified work emails a month – the field runs from $200 to $1,500 among live APIs you can buy today, and further in both directions once closed-beta and enterprise-only options are counted.

When is Crustdata still the right choice? When you need live signal monitoring more than cheap enrichment. Crustdata’s watcher system, with tiered refresh frequencies down to daily, is genuinely strong. If your scoring model depends on those signals, switching to save money can cost you the thing you were paying for.

Crustdata’s data is rarely the complaint. What sends teams looking is the commercial model: no self-serve plan, no free tier, no published pricing, and a sales call before you can even trial it. Here are the ten strongest alternatives, priced from each vendor’s own page.

Key Takeaways

• Cost and sales-led buying, not data quality, are why teams leave Crustdata – you can’t self-serve, can’t start free, and can’t price a workload without a call
• Limadata is the strongest overall alternative for real-time enrichment across AI agents, recruiting, and GTM, with published per-endpoint pricing and a free tier that returns real values
• Cost per credit is the wrong comparison – credits aren’t equivalent units, and normalizing to a real workload changes the ranking substantially
• Plan minimums drive real cost more than credit rates do – CompanyEnrich has the cheapest credits in this group and still costs $549/month for a common contact-enrichment workload
• Free tiers vary enormously: Landbase gives 1,000 credits with no expiry, Coresignal gives 2,000 for seven days, People Data Labs excludes contact data from its free tier entirely, and Enrich Layer and LeadMagic offer none at all
• Review volume is thin across this whole category – most of these tools have well under 30 G2 reviews, because they’re APIs bought by engineers rather than seats bought by sales teams; weigh a free-tier test above any rating
• Match the model to the workload: bulk warehouse ingestion, real-time agent enrichment, and database-wide cleanup are three different purchases, and no single vendor wins all three

What Is Crustdata and Why Look for Alternatives?

Crustdata is an API-first B2B data platform for developers and AI agents, aggregating continuously from live sources rather than serving periodic database refreshes. It’s a good product: accuracy and coverage hold up against anything in this comparison, and the live signal endpoints are genuinely differentiated. Teams don’t leave because the data disappointed them. They leave because of what it costs and how you have to buy it.

Key Crustdata strengths:

• Strong accuracy and coverage, competitive with any provider in this comparison
• Live aggregation rather than monthly batch refreshes
• Company screening across 250+ firmographic criteria, people profiles with 90+ datapoints
• Watcher endpoints with webhook delivery for job changes, funding, and hiring events
• Tiered watcher refresh frequency, from 30-day down to daily
• Additive enrichment pricing – you pay for the base profile, then only for the fields you request
• Free autocomplete and company identify endpoints
• Low-cost discovery: search bills at 0.03 credits per result, and returns nothing means it costs nothing

Crustdata limitations:

• No self-serve plans and no free tier. There’s no way to sign up and start calling the API. Evaluating Crustdata means booking a sales call and being qualified before you can trial it, which rules it out for anyone who wants to test on a Friday afternoon.
• Sales-led pricing. Because every deal goes through a rep, pricing reflects a sales-led motion rather than published self-serve rates – and cost is the most common reason teams start looking elsewhere.
• No published pricing. Crustdata’s pricing page carries no tier prices. Plan costs require contacting them.
• Enterprise-only endpoints. Contact enrichment, batch contact enrichment, social post search and enrich, developer platform data, and employee review data all require an enterprise contract.
• Plan-gated live endpoints. Live Company and Person endpoints need the right plan; only Web Search and Web Fetch are guaranteed on self-serve.
• Credits expire after six months from purchase date.
• Documented pricing volatility. Crustdata’s own docs warn that pricing can change by plan, entitlement, and endpoint version, and advise confirming costs before planning production usage.

Crustdata reviews: No G2 profile. 4.4/5 on Product Hunt.

The practical problem isn’t data quality – it’s that a developer evaluating Crustdata can’t calculate what a workload will cost, can’t tell whether the endpoint they need is reachable on the plan they can afford, and can’t try it at all without first getting through a sales call. Every tool below lets you answer at least one of those questions before talking to anyone, and most let you answer all three. That’s the gap they compete in.

How We Compared These Tools

Every pricing figure came from the vendor’s own pricing page, captured September 2026, with per-endpoint credit costs from vendor docs and ratings from G2. Where no public pricing exists, we say so rather than citing third-party estimates.

Pricing pages change often, so verify before you buy.

Crustdata Alternatives at a Glance

The last column prices every vendor on the same job: 10,000 verified work emails in a month, on the cheapest plan that can actually deliver them. Across tools you can buy self-serve today, that runs from $200 to $1,500 – a 7.5× spread driven far more by plan minimums and per-endpoint credit costs than by headline pricing.

The 10 Best Crustdata Alternatives

1. Limadata: Best for real-time data enrichment for AI agents, recruiting, and GTM

Limadata inverts the usual enrichment model. Instead of serving records from a database that’s periodically refreshed, it queries multiple trusted sources on demand and cross-references them at request time. That matters most where accuracy isn’t negotiable: an AI sales agent querying Limadata the moment a prospect hits your site gets their current title and latest funding round in milliseconds, which is what lets it open with the new VP role and the Series B rather than something six weeks stale. The same model powers Watch alerts, so a recruiting platform can be notified the instant a tracked candidate changes jobs. Access is available through the API, webhooks, an MCP server, Claude Code, and Cowork.

Key Limadata advantages:

• 50+ endpoints, one of the most robust sets available from any provider in this comparison
• 550M+ contacts and 60M+ companies, growing continuously rather than on a batch refresh cycle
• Excellent personal email coverage – ranked #2 among personal email providers in Clay’s waterfall, a category most API-first providers don’t compete in at all
• Watch API with webhooks for job changes, promotions, funding events, and hiring spikes
• Hashed email and ad audience endpoints for building match-ready audiences on ad platforms, which almost nothing else on this list offers
• Flat file delivery available alongside the API, for teams that want to load data directly rather than call endpoints
• Hands-on support with features built on request – several endpoints exist because customers asked for them, and reviewers consistently cite responsiveness as a reason they stayed

Limadata pricing structure:

• Free: $0/month – 100 credits (up to 100 work emails, 10 mobile numbers), or a 500-credit trial for qualified demos
• Starter: $50/month – 2,500 credits at $0.02/credit
• Pro: $200/month – 20,000 credits at $0.01/credit, scalable to 100,000
• Enterprise: Custom – batch endpoints, custom rate limits, annual credit expiration

Per-endpoint credit costs – person enrich 1, company enrich 1, work email 1, mobile 10, web search 0.1, extract 0.1, company jobs 2 – are published in full on the Limadata pricing page, along with top-ups at 150% of plan rate for months you run over.

Limadata limitations:

• You need to be comfortable working with an API. Limadata is infrastructure rather than a list-building UI, so there’s a baseline of technical comfort required. That doesn’t mean you need an engineering team – connecting the MCP server to Claude is enough to start querying live data in plain language – but if you want a point-and-click prospecting tool with no setup, this is a lower layer of the stack than you’re looking for.

Limadata reviews: 5.0/5 on G2 (5 reviews).

Best for: Teams building AI agents, running recruiting workflows, or powering GTM motions that need people, company, contact, and signal data live at query time, with transparent per-operation pricing.

2. LeadMagic: Best pay-per-result pricing transparency

LeadMagic offers verified emails, mobile numbers, company intelligence, and hiring signals through an API, a terminal CLI, and a hosted MCP server. Its defining characteristic is pricing transparency – monthly rates, annual rates, credit allocations, seat counts, and per-endpoint costs are all published on a single page, which is rarer in this category than it should be.

Key LeadMagic advantages:

• Credits deducted only on successful results – failed matches cost nothing
• Search spends no credits on Essential and above; Professional and Ultimate add an unmetered search API
• Credit rollover up to two months banked on Essential and above
• MCP server and CLI included on every plan, including the cheapest
• 15+ endpoints on one shared credit pool and a single API key
• Efficient credit costs: email 1, mobile 5, validation 0.25, employee finder 0.05

LeadMagic pricing structure:

• Basic: $49.99/month ($490/year) – 2,000 credits/month, 1 seat, search not included
• Essential: $99/month ($990/year) – 5,000 credits/month, 3 seats, search included
• Growth: $249/month ($2,490/year) – 20,000 credits/month, 5 seats
• Professional: $499/month ($4,990/year) – 50,000 credits/month, unmetered search API
• Ultimate: $849/month ($8,490/year) – 100,000 credits/month
• Enterprise: From $2,490/quarter

LeadMagic limitations:

• No free tier. You can’t evaluate the data without paying first, which is a meaningful constraint in a category where most competitors let you benchmark match rates before committing. Note that several third-party sources – and at least one page on LeadMagic’s own site – still reference 100 free credits; that offer has been discontinued, and the pricing page FAQ is the current source of truth.
• No rollover on Basic, and search isn’t included at that tier either, which makes the entry plan noticeably weaker than its price implies.
• Inconsistent results across lists. User ratings cluster at the extremes rather than the middle, which suggests it performs well on most lists and poorly on some. Worth testing against your own data before committing.
• Contact-data focus. Less firmographic depth than a dedicated company data provider.

LeadMagic reviews: 4.3/5 on G2 (19 reviews).

Best for: Outbound teams and developers who want verified contact data with genuinely predictable, published costs.

Limadata Alternative: Limadata Starter

3. CompanyEnrich: Best budget option for company firmographics

CompanyEnrich is an API-first company data platform covering roughly 30 million validated company profiles and 170 million people profiles, distilled from a much larger pool of raw records. The trade is deliberate: curation over raw volume. It offers full API access on every plan and runs its own MCP server.

Key CompanyEnrich advantages:

• Lowest cost per credit in this comparison at $0.0011 on the Scale plan
• Steep volume discount – 8.9× cheaper per credit from Starter to Scale
• Free Preview API returning up to 25 results without consuming credits, plus free autocomplete and logo endpoints
• 11 endpoints including funding, ad intelligence, jobs, headcount tracking, and reverse email lookup
• AI-powered lookalike discovery and semantic company search
• Full API access on every tier, with no feature gating below Scale

CompanyEnrich pricing structure:

• Free trial: 500 credits
• Starter: $49/month – 5,000 credits at $0.0098/credit
• Pro: $149/month – 50,000 credits at $0.0030/credit, with rollover
• Scale: $549/month – 500,000 credits at $0.0011/credit, with rollover, Preview API, async and batch endpoints
• Annual plans available but not published

CompanyEnrich limitations:

• Expensive contact data despite cheap credits. Find Email costs 10 credits and Find Mobile costs 30, so the low per-credit rate doesn’t translate to low contact costs. Ten thousand emails needs 100,000 credits, which only exists on the $549 Scale plan.
• No credit rollover on Starter – only Pro and Scale.
• Company-first. People data exists but is secondary; you may still need a contact provider alongside it.

CompanyEnrich reviews: 4.8/5 on G2 (29 reviews) – the highest verified average in this comparison.

Best for: Teams whose primary need is company firmographics, tech stack, and lookalike discovery at low cost.

Limadata Alternative: Limadata Starter

4. Coresignal: Best for warehouse-scale bulk datasets

Coresignal aggregates public web data from 15+ sources into structured datasets covering companies, employees, and job postings – over 900 million employee profiles and 475 million job postings. It’s built for data engineering teams loading records into their own infrastructure, with Elasticsearch DSL querying and both API and flat-file delivery.

Key Coresignal advantages:

• Search is free. Elasticsearch DSL, semantic search, and filter queries consume no credits; you’re billed only on collect and enrich.
• Up to five years of historical data, which most competitors don’t offer
• Multi-source records that merge and deduplicate across providers
• Agentic Search API with both fast and reasoning modes
• Webhooks for change notification, plus a Historical Headcount API
• Certified by the Ethical Web Data Collection Initiative, with a documented public-data-only sourcing policy
• Eight tiers, so you can size the plan closely to actual usage

Coresignal pricing structure:

• Free trial: 2,000 credits, 7 days
• Mini: $49/month – 2,500 credits
• Starter: $199/month – 12,000 credits ($2,149/year for 144,000)
• Pro: $499/month – 35,000 credits ($5,389/year for 420,000)
• Growth: $1,000/month – 150,000 credits ($10,800/year for 1.8M)
• Premium: $1,500/month – 1,000,000 credits ($16,200/year for 12M)
• Scale: $3,000/month – 4,000,000 credits ($32,400/year for 48M)
• Elite: $5,000/month – 10,000,000 credits ($54,000/year for 120M)
• Datasets sold separately, from $1,000

Coresignal limitations:

• The entry plan is smaller than it looks. A base employee or company record costs 10 credits and a multi-source record costs 20, so Mini’s 2,500 credits buys 125–250 records a month.
• Contact enrichment is gated to the $499 Pro plan and costs 20 credits per record, and Real-time Employee API is gated to Growth at $1,000.
• Rollover only on Premium and above for monthly plans – and the annual plans show no rollover at any tier.
• No built-in email verification, and users commonly report credits depleting faster than expected given the 10–20 credit record cost.

Coresignal reviews: 4.5/5 on Datarade. No G2 profile.

Best for: Data teams ingesting large volumes into a warehouse, and anyone who needs historical records or documented ethical sourcing.

Limadata Alternative: Limadata Enterprise

5. Explorium: Best multi-source data layer for GTM agents

Explorium positions itself as a B2B data layer for building GTM agents, aggregating from 50+ sources and delivering through an API, an MCP server on AWS Marketplace, bulk export, and native integrations. Its agent tooling is mature – the MCP server lets an agent select from roughly 30 enrichment categories rather than calling pre-mapped endpoints.

Key Explorium advantages:

• 50+ underlying data sources aggregated into one interface
• MCP server integrating with Claude, Claude Code, n8n, LangChain, LangGraph, CrewAI, and Zapier
• Free contact preview before committing credits
• Intent data alongside firmographics, which most API-first providers in this comparison don’t offer
• Custom signal creation and dynamic refresh

Explorium pricing structure:

• Free Trial: $0 – 100 credits, valid 90 days
• Starter: $99.99 one-time – 2,500 credits at $0.04/credit
• Growth: $749.99 one-time – 25,000 credits at $0.03/credit
• Scale: $7,499.99 one-time – 500,000 credits at $0.015/credit
• Enterprise: Custom

Explorium limitations:

• These are one-time purchases, not subscriptions. Packages are non-refundable, don’t auto-renew, and service stops when credits run out. Paid credits expire after 12 months with no rollover.
• Highest entry rate here at $0.04 per credit.
• Data freshness complaints. G2 reviewers report contacts shown as current at a company having already left, taking the email address stale with them.
• Inconsistent SMB coverage – reviewers note limited or outdated firmographics on smaller accounts.
• No granular contact billing – you can’t request only personal or only professional emails.

Explorium reviews: 4.6/5 on G2 (28 reviews).

Best for: Teams that want breadth across many sources for CRM enrichment, lead scoring, and intent-driven GTM agent workflows.

Limadata Alternative: Limadata Pro

6. People Data Labs: Best for raw person data at scale

People Data Labs offers one of the largest person datasets available through an API – roughly 1.5 billion profiles and 74 million company records – with excellent documentation and a clean REST interface. It’s a developer’s data source rather than a GTM platform: no dashboard, no CRM connector, no workflow automation.

Key People Data Labs advantages:

• Very large person coverage with deep work history, education, and skills data
• Well-documented REST API with strong SDK support
• Free Autocomplete and Cleaner APIs that consume no credits
• Snowflake, Salesforce, and Databricks integrations
• Bulk enrichment consuming up to 100 credits in a single request
• Strong independent accuracy results in third-party field-yield benchmarking

People Data Labs pricing structure:

Person and Company data are sold as separate product lines, each with its own three tiers.

Person APIs:

• Testing (Free): $0 – up to 100 credits/month, no commitment. Contact data not included.
• Self-Serve (Pro): From $98/month, starting at 350 credits/month ($0.28/credit). Contact data included, premium field access, CSV enrichment, email support. Annual from $940.80 for 4,200 credits at $0.224/credit.
• Bulk Data (Enterprise): Custom pricing – annual contracts, all APIs, data license feeds, additional field bundles, designated success team, SSO/SAML.

Company APIs:

• Testing APIs (Free): $0/month – up to 100 monthly records, always free, ISO and SOC 2 Type 2 compliant data.
• Full APIs (Pro): $100/month, starting at 1,000 monthly records ($0.10/credit), premium fields, email support. Annual from $960 for 12,000 records at $0.08/credit.
• Bulk Data (Enterprise): Custom pricing – API or data license feeds, custom contract and usage terms, SSO/SAML.

Contact lookups through the Person Identify API are metered separately again, at $0.55 down to $0.50/credit monthly and $0.44 down to $0.40 annually. Enterprise is required above 100,000 credits.

People Data Labs limitations:

• By far the most expensive per credit here. The $0.28 entry rate is 28× Limadata’s Pro rate.
• The free tier can’t be used to evaluate contact data. PDL’s Person free plan states plainly that contact data is not included, so you can inspect schema and coverage but cannot check whether the emails and phone numbers are any good until you’re paying.
• Person and Company are separate product lines, each with its own free, Pro, and Enterprise tiers – needing both means two subscriptions at $98 and $100/month respectively.
• Contact data is a separate, pricier meter through Person Identify, on top of enrichment costs.
• Self-serve caps out early. Ten thousand contact lookups a month exceeds the published tiers entirely and forces an enterprise conversation.
• Monthly refresh cadence means changes between refreshes are missed.

People Data Labs reviews: 4.3/5 on G2 (17 reviews).

Best for: Engineering teams building identity resolution or talent intelligence products where person-data breadth matters more than cost.

Limadata Alternative: Limadata Pro

7. Enrich Layer: Best for teams migrating off Proxycurl

Enrich Layer provides people, company, jobs, contact, school, search, and logo APIs across 1.2 billion profiles and 50 million company records, on a shared credit balance. It became prominent after Proxycurl wound down in 2025 following litigation from LinkedIn, and it publishes a migration guide and a knowledge base article specifically for former Proxycurl users. Its endpoint structure and credit model closely mirror Proxycurl’s, which makes migration unusually low-friction.

Key Enrich Layer advantages:

• Proxycurl-compatible migration path, with documented transition guidance
• On-demand crawling rather than purely cached data
• Genuine pay-as-you-go with no subscription required
• Steepest volume discount here – 13× from PAYG entry to the top annual tier
• PAYG credits don’t expire unless the account is inactive for 18 months
• Seven APIs plus a CLI for scripts and CI pipelines

Enrich Layer pricing structure:

Pay-as-you-go, no commitment:

• $10 – 100 credits ($0.10/credit)
• $100 – 3,788 credits ($0.0264/credit)
• $1,000 – 46,297 credits ($0.0216/credit)

Annual subscriptions:

• Starter: $588/year – 35,000 credits ($0.0168/credit)
• Growth: $3,588/year – 350,000 credits ($0.0103/credit)
• Pro: $10,788/year – 1,258,600 credits ($0.0086/credit)
• Ultra: $22,788/year – 2,954,000 credits ($0.0077/credit)
• Enterprise: From $24,000/year

Enrich Layer limitations:

• No free tier – one of only two tools here, alongside LeadMagic, with no free entry point.
• Subscriptions are a 12-month commitment with a fee for cancelling early.
• Contradictory credit expiry documentation. The pricing page says credits are delivered upfront and yours to use at any pace; other pages indicate subscription credits expire at the end of each billing cycle. Worth clarifying before committing.
• Corporate relationship to Proxycurl is not publicly confirmed – it offers a compatibility path, but whether the same entity operates it hasn’t been publicly established.

Enrich Layer reviews: No rating available – no G2, Trustpilot, or Capterra presence found.

Best for: Teams with existing Proxycurl integrations, and anyone who wants meaningful pay-as-you-go without a subscription.

Limadata Alternative: Limadata Starter

8. MixRank: Best for enriching an existing B2B database at scale

MixRank has been building B2B datasets since 2011 and sells to data teams enriching their own platforms rather than to end users. You connect an existing database and use MixRank as a source of truth – filling gaps, correcting errors, finding look-alike records, and keeping profiles current as people change jobs. It scans over 5 million profiles a day and processes roughly 3 petabytes a month, and its customer logos include Oracle, Meta, Intel, Amazon, and Adobe.

Key MixRank advantages:

• Cleanest per-record math in this comparison – one credit equals one operation equals one record, with no field multipliers
• 800M+ B2B records across 150+ data attributes, plus 70M companies indexed and 1.4B job posts
• Bidirectional mapping – email to social profile and back, website URL to company record and back
• Profile URL repair: MixRank records every URL transformation it observes, so broken or outdated profile links in your database can be corrected against it
• On-demand profile refresh through LiveScan, rather than waiting for a batch cycle
• Influence scoring on both people and company records
• Delivery by API, flat file, PostgreSQL tables, or a MixRank-hosted database, aggregated from 50+ sources
• Free data sample and API key with no credit card, so you can test coverage against your own records first

MixRank pricing structure:

Each endpoint is a separate subscription, on annual contracts:

• Enrich, Match, and Posts (identical pricing): 100,000 credits/month $1,000 · 250,000 $1,750 · 500,000 $3,250 · 1,000,000 $6,000 · above that, custom
• LiveScan: 100,000 credits/month $1,500 · 250,000 $3,000 · 500,000 $5,000 · 1,000,000 $8,000 · above that, custom
• Data Feeds and the Mobile Apps & SDK platform are quoted separately

MixRank limitations:

• Endpoints are billed separately. Enrich, Match, and LiveScan at entry volume together cost $3,500/month – $42,000 a year.
• $12,000/year practical minimum for a single endpoint on an annual contract. There’s no way to start small.
• No verified work email product, so it can’t serve contact-enrichment workloads. Match resolves an email to a record, which is reverse lookup, not email finding.
• Prices render client-side, meaning they’re effectively invisible to search engines and most third-party sources report figures from the wrong product line.

MixRank reviews: 3.8/5 on G2. TrustRadius scores it 5.8/10 on Sales Intelligence Data Standards.

Best for: Data teams enriching an existing contact or company database at scale, and platforms embedding licensed B2B data into their own products.

Limadata Alternative: Limadata Enterprise

9. Landbase: Best for natural-language audience building

Landbase is an agentic GTM platform built around natural-language targeting – you describe an ideal customer profile in plain language and it maps the addressable market and exports a qualified audience with verified contacts. It’s powered by GTM Omni, an in-house model for go-to-market automation, and raised a $30M Series A in July 2025. Structurally it differs from everything else here: rather than owning a first-party dataset, it routes enrichment through 20+ providers automatically and returns the first verified result. It pairs this with agentic search, lookalike expansion, AI qualification, and 25 buying-signal triggers computed from 1,500+ enrichment fields, accessible via a CLI designed for Claude Code and Codex workflows.

Key Landbase advantages:

• Waterfall routing across 20+ providers, which typically beats any single source on match rate
• Search, lookalike expansion, and misses are all free – you’re charged only for verified results
• 1,000 free credits with no credit card and no expiry
• CLI built for terminal and agent workflows, with JSONL, CSV, and Parquet exports
• Buying signals including funding, hiring surges, leadership moves, and tech adoption
• Named a Gartner Cool Vendor in AI for Marketing (2025)

Landbase pricing structure:

• Free: $0 – 1,000 credits, no card, no expiry
• Tier 1: $499/month – 15,000 credits at $0.033/credit
• Tier 2: $1,999/month – 75,000 credits at $0.0267/credit
• Tier 3: $4,999/month – 200,000 credits at $0.025/credit
• Enterprise: Custom

Landbase limitations:

• Highest entry price among self-serve options at $499/month, roughly ten times Limadata, CompanyEnrich, or LeadMagic.
• Shallowest volume discount here – only 1.3× from entry to top tier, so scaling up barely improves your rate.
• Aggregator, not a data owner. Coverage and cost depend on the underlying providers, which is a dependency worth understanding.
• Mobile numbers cost 10 credits at $0.33 each.
• Plans are unnamed, and the free credit allowance is described inconsistently across their own site.

Landbase reviews: 4.5/5 on G2.

Best for: Sales, marketing, and RevOps teams who want to define an ICP and map total addressable market conversationally, with waterfall enrichment running behind it.

Limadata Alternative: Limadata Pro

10. MoltSets: Best flat-rate model

MoltSets abandons the credit model almost entirely. Its plans offer unlimited enrichment records subject to request rate limits and a fair use policy, with only mobile phone lookups metered as separate tokens. Every plan includes the full API surface: verified business and personal email with risk scoring, real-time carrier-verified mobile, people and company search, email validation, and reverse email lookup.

Key MoltSets advantages:

• Unlimited enrichment records on every paid plan – no per-lookup credits
• Dramatically cheapest option for high-volume email enrichment at $27/month, though it runs on a weekly refresh cycle rather than querying live
• Risk scoring included on both business and personal email endpoints
• Real-time carrier verification on mobile numbers
• Full API surface on every tier, including free
• MCP guide and skills library for agent integration

MoltSets pricing structure:

All tiers below run on MoltSets’ weekly refresh cycle rather than querying live, and the product is in closed beta.

• Free: $0 – 1,000 enrichment records lifetime, 1,000 requests/5 hours, 10 mobile tokens
• $27/month – unlimited records, 5,000 requests/5 hours, 10 mobile tokens
• $97/month – unlimited records, 75,000 requests/5 hours, 50 mobile tokens
• $997/month – unlimited records, 900,000 requests/5 hours, 250 mobile tokens
• Extra mobile tokens from $0.20; flat files by request

MoltSets limitations:

• Weekly refresh cycle, not queried live. This is the most important thing to know about the price. The database is refreshed every 7 days (job changes are processed fortnightly), and external vendors are only checked when a record isn’t already held in-house, so accuracy between refreshes lags the live APIs in this comparison. The $27 buys volume, not real-time freshness.
• Currently in closed beta. Access is via an application form rather than self-serve signup, so it isn’t a tool you can adopt on demand today.
• “Unlimited” is bounded by request rate limits and separate fair use policies for enrichment and search.
• Mobile numbers are the real cost driver – token allowances are small, and phone-heavy teams will buy extras.
• No track record and a very limited public footprint.
• A discounted rate is available in exchange for social media promotion, which is a conditional price rather than a list price.

MoltSets reviews: No rating available – expected for a product still in closed beta.

Best for: High-volume email enrichment where flat-rate economics beat per-credit billing – once general availability arrives.

Why Limadata Fits Real-Time AI Agent, Recruiting, and GTM Workflows

Across this comparison, three problems come up repeatedly: pricing you can’t calculate without a sales call, data that’s already stale by the time you query it, and credits that expire before you use them. Limadata was built around avoiding all three.

Published, per-operation pricing. Person enrich, company enrich, and work email each cost one credit. Web search and extraction cost 0.1. Mobile numbers cost 10. Those numbers are on the pricing page, which means you can model a workload before signing up rather than after.

Live data instead of cached records. Data is fetched at query time from web crawling, registries, and partner networks, then cross-referenced across sources. This matters more than it sounds: Explorium’s own reviewers report contacts listed as current at a company who had already moved on, and PDL refreshes monthly. A query-time model has no staleness window – the question isn’t when the database was last refreshed, it’s what’s true right now. For anything triggered by an event, from an agent responding to a site visit to a recruiter reacting to a job change, that difference is the whole product.

Genuinely agent-native. MCP, Claude Code, and Cowork support alongside REST and webhooks. Several vendors here now ship MCP servers, but the combination of MCP plus a free tier that returns real values means an agent can be pointed at live data on day one without procurement.

One data layer across three workloads. The same endpoints serve all three of the use cases this product is built for, which is why teams tend to consolidate onto it rather than run separate tools:

• AI agents – live enrichment at query time, an MCP server, and web search and extraction at 0.1 credits for RAG pipelines
• Recruiting – people search across 90+ attributes, personal email coverage ranked #2 in Clay’s waterfall, and Watch alerts that fire the moment a tracked candidate changes roles
• GTM – company search across 200+ attributes, verified work emails and mobiles, funding and hiring signals, plus hashed email and ad audience endpoints for paid targeting

Credit flexibility. Top-ups at 150% of plan rate mean a usage spike doesn’t force a tier upgrade – a contrast with Explorium’s hard stop when a one-time package runs out.

Frequently Asked Questions

What is the best free Crustdata alternative?

Crustdata has no free tier of its own, so any of these is a step up on that count. Landbase offers the most generous no-strings free tier at 1,000 credits with no credit card and no expiry. Limadata’s free plan gives 100 credits with full endpoint access and returns real contact values rather than placeholders, which makes it the better option for genuinely evaluating data quality. Avoid judging a provider on People Data Labs’ free tier – its Person plan excludes contact data outright, so you can’t assess email or phone quality without paying. Note that Enrich Layer and LeadMagic have no free tier, so evaluating either means paying first.

Which Crustdata alternatives support MCP for AI agents?

Limadata, CompanyEnrich, Explorium, and LeadMagic all ship MCP servers. Limadata additionally supports Claude Code and Cowork; Explorium’s MCP server is distributed through AWS Marketplace and connects to LangChain, LangGraph, and CrewAI; LeadMagic includes MCP access on every plan including its cheapest tier. MoltSets publishes an MCP guide, and Landbase offers a CLI built for Claude Code and Codex workflows.

Do Crustdata credits expire?

Yes. Crustdata credits are valid for six months from the date of purchase. Among the alternatives, expiry policies vary widely: Explorium’s paid credits expire after 12 months with no rollover, Enrich Layer’s pay-as-you-go credits don’t expire unless the account is inactive for 18 months, Coresignal offers three-month rollover only on Premium and above, and LeadMagic banks up to two months of unused credits on Essential and higher.

Which Crustdata alternative is cheapest per verified email?

Normalized to 10,000 verified work emails a month at list rates: Limadata at $200, LeadMagic at $249, Enrich Layer at $299 (on an annual commitment), Landbase at $499, CompanyEnrich at $549, and Coresignal at $1,500 – the last because contact enrichment costs 20 credits and requires the Premium tier. MoltSets would be cheapest at $27, but it’s in closed beta and runs on a weekly refresh cycle rather than querying live, so its accuracy isn’t comparable to the live APIs above. People Data Labs exceeds its self-serve tiers entirely at that volume.

Can I migrate off Crustdata without rewriting my integration?

Not directly – no vendor here offers Crustdata endpoint compatibility. The practical approach, and the lesson most teams took from the Proxycurl shutdown, is to write a thin adapter layer in your own code that isolates the provider behind an internal interface. That way switching providers means rewriting one module rather than every call site. It’s worth doing regardless of which vendor you choose, because any provider can change its pricing, gate an endpoint, or shut down.

Making the Right Choice

The right Crustdata alternative depends far more on your workload shape than on any overall ranking.

Choose by what you’re actually doing:

• Real-time enrichment for AI agents, recruiting, or GTM workflows → Limadata
• Verified contact data with predictable published costs → LeadMagic
• Company firmographics on a tight budget → CompanyEnrich
• Bulk datasets loaded into a warehouse → Coresignal
• Breadth across many sources for CRM enrichment and lead scoring → Explorium
• Person-data depth for identity resolution products → People Data Labs
• An existing Proxycurl integration → Enrich Layer
• Enriching or repairing an existing database at scale → MixRank
• Conversational ICP definition and TAM mapping → Landbase

Before committing, run the same 500 records through two or three providers and compare match rate, field completeness, and cost per successful result. Nearly every vendor here has a free tier or trial that makes this cheap to do, and the results are frequently surprising – headline coverage numbers correlate poorly with performance on any specific ICP.

Two things are worth checking regardless of who you pick: whether the endpoints you need are available on the plan you can afford, and what happens to unused credits at the end of the billing period. Those two questions account for most of the gap between what teams expect to pay and what they end up paying.
