What is a funding data API?

A funding data API returns company financing events (round, amount, stage, and investors) as structured data you can query and pipe into your own tools. The Signalbase Funding API adds one thing most do not: it detects the event as it happens and pairs it with the first hire that follows, so you get the timing, not just the record.

How fast does Signalbase detect a new round?

Events are pushed on a flow, not a scheduled refresh. Typical lag from public announcement to the event landing in your endpoint is under a minute, against the monthly cycle most funding databases run on. That figure is a floor for cleanly resolvable companies, not a guarantee across every raise.

Can I filter funding events by stage, amount, or region?

Yes. Every field is a query parameter: stage, amount range, country or region, lead investor, and detection timestamp. Narrow the flow to your ICP before it reaches your CRM, with no post-processing on your side.

Does the Funding API cover every funding round?

No, and we would rather say so. Coverage is strongest where the round is public and the company name resolves cleanly. Stealth rounds, generically named entities, and thinly reported regions are where it drops off. If you need an exhaustive historical census, a bulk database still wins. If you need to catch fast movers early, this is built for that.

How do I start using the Funding API?

Start a 7-day trial, pull your first events in a few lines, and test against real data. Full endpoints and parameters are in the documentation.

Stock vs flow

Databases repurpose data on 30 days. We source the moment it happens.

A funding live stream that pushes ICP-like accounts is different from getting 200M contacts. One makes you guess when to reach out, the other shortens your sales cycles.

Benchmark

Most tools stop at raw funding data. We verify and contextualize every round.

Every other tool hands you one piece of the pipeline, usually sourcing. The Funding API delivers a complete, verified round inside a full company profile.

Delivery

Three ways to push the data to you.

The same funding events, delivered where you work: pull them on your schedule, have them pushed the moment they land, or wire them natively into your agents.

Pull

REST API

Poll the funding endpoint with a since cursor on your own schedule.

Push

Webhooks

We post the event to your endpoint the moment it lands. This is the flow, not a nightly batch.

Native

MCP

Wire the same signals straight into your agent or GTM tooling over the Signalbase MCP.

Built for

Where teams point this API.

Timed outbound

Wake your sequences on the compound trigger, not on a stale funding list everyone else already bought.

Account scoring

Feed real-time rounds into your model so freshness and stage lift the accounts that just got budget.

Territory alerts

Route each new round to the rep who owns the account the same day it clears, straight into your CRM.

Building internal AI SDRs

Find your ICP once and let results populate while you never touch the UX again.

We have tried other financial signals providers, such as Crunchbase. Despite being more expensive, they could not match Signalbase's timeliness or the ability to trace data back to source posts.

We have been searching for a signal infrastructure for months and happily ended up with Signalbase. The data is top tier and the platform and API are very straightforward.
