Real-time Delivery

Every signal follows the same structured event schema no matter the source — job change, funding round, or new hire.

Real‑time signals, no pipeline to build.

Unified schema with managed polling, diffing, and “what changed” events—pay only for the entities you track.

The legacy approach

Stale data & gaps

Data delayed by weeks or months. Miss the window of opportunity entirely.

Manual polling

Waste engineering cycles building scrapers that break every time a site changes.

DIY change detection

Store snapshots, diff results, dedupe, and emit “what changed” events.

Fragmented sourcing

Manage 10+ vendors to get coverage across news, hiring, and social.

The Limadata way

Live stream delivery

Real-time signals pushed to your system the second they are indexed.

Managed infrastructure

Polling, retries, backfills, normalization, diffing, and change events handled for you.

Comprehensive signals

People, company, and market events in one feed.

Pay per tracked entity

Stop overpaying for bulk seats. Scale costs linearly with your target accounts.

Deliver signals wherever you work

Slack & Discord

Instant alerts for sales teams.

CRMs & CDPs

Sync signals to HubSpot & Salesforce.

Custom endpoints

Direct integration via webhooks.

GTM platforms

Trigger sequences in Apollo & Outreach.

Signal Data FAQ

What's a Watch?

A Watch is a subscription you activate on a person or company. Once active, Limadata continuously monitors that entity and pushes a webhook event the moment a tracked signal — a job change, funding round, new hire, and more — is detected. No polling required.

What signals can I track?

On people, you can watch for job changes, promotions, social mentions, social posts, and news mentions. On companies, you can watch for funding rounds, new hires, job postings, news mentions, and social posts.

How are signals delivered?

Every signal is delivered as a structured JSON webhook event the instant it's detected — no polling, scraping, or diffing required on your end. Events can be routed to Slack & Discord, CRMs & CDPs like HubSpot and Salesforce, custom endpoints, or GTM platforms like Apollo and Outreach.

How is Signal Data priced?

Signal Data is priced per tracked entity rather than a flat seat license, so cost scales with the accounts and people you actually watch, not bulk credits. Book a call with our team to review coverage and get a plan sized to your target account volume.
