}Funding rounds, executive hires, headcount growth, tech-stack changes, product launches, and web mentions — one schema for all of them.
Push events to your endpoint as they are detected, or hold a persistent SSE stream. Poll historical signals when you need to backfill.
Every event carries a fit score based on the ICP you define, so you act on the accounts that matter and drop the noise.
Kick off an outbound sequence automatically the moment a matching account raises funding or hires a new leader.
Surface in-market accounts at the top of your users’ workflow, scored and timestamped.
Route a scored signal to the rep who owns the account via Slack, email, or your CRM the second it fires.
One key across every Bunlead API. Credit-based pricing, a free sandbox, and generous rate limits — 10K calls/month on Starter, scaling to 1M+ with a custom SLA. Failed lookups are always free.
Use webhooks for durable, at-least-once delivery into your backend, and the SSE stream for live UI or dashboards. Both carry the same event schema.
The graph refreshes hourly, so most events reach your webhook within an hour of the underlying change being detected.
Yes. The /signals/search endpoint lets you query past events by company, type, and date range to seed or replay your pipeline.
You define an ICP once — firmographics, geo, tech — and every event is scored 0–100 for fit, so you can threshold on the accounts worth acting on.
