Signalbase - Funding & Business Signals API

Real-time GTM signal infrastructure providing an API used inside data vendors, GTM teams at companies like HubSpot, Plaid, and Convert, and GTM platforms including Bytemine, Salesforge, Databar, CompanyEnrich, Signalist, Caide, and Master Inbox. Signalbase detects new funding rounds, acquisitions, hiring signals, executive job changes, and company events from across the web in under a minute. Today we've indexed 50k+ funding rounds, 18k+ acquisitions, 679k+ hiring signals, 960k+ executive job changes, 19k+ investor profiles, and 189k+ companies generated from any of these signals, and these numbers grow every minute. Every signal ships with original source attribution. Powered by Signalbase.

Filter by country, industry, round type, employee count, seniority, and more. Use it to power lead generation, investment research, competitive intelligence, AI agent workflows, and market analysis.

Signalbase vs. database scrapers

Most "funding data" or "company data" actors on Apify scrape Crunchbase or similar databases. We don't.

• Source attribution. Every signal includes the original news article, press release, ATS posting, or LinkedIn URL where we detected it. Not a database lookup, the actual moment it happened.
• Real-time detection. Signals appear in our API within minutes of the original event, not days or weeks after a static database is updated.
• Landscape-wide. We monitor every company, not just a target list. New companies appear the moment they show signal activity.
• Verified and contextualised. Every signal includes a confidence score, verification status, and full company profile. No enrichment step required on your side.
• Enterprise-grade reliability. 99% uptime, with continuous aggregation from web sources.

They give you a database. We give you a moment.

Built for

• B2B data vendors refreshing static databases with live signals and context, turning stale company records into ones that reflect what's happening right now
• AI SDR and GTM platforms boosting their reasoning and contextualisation models with sub-minute event data. Signals occurring a minute ago, not yesterday's snapshot
• AI agents that need fresh, source-attributed signals for autonomous outbound, research, and decision-making
• Lead generation tools enriching firmographics with real buying moments. Funding, hiring, leadership changes, M&A
• GTM teams and agencies running signal-based outbound, account prioritisation, and pipeline generation on real buying moments, in-house or for clients
• Investment research teams monitoring funding and M&A activity across the landscape

Which Signalbase Actor should I use?

This Actor is the unified entry point. All six signal types from one Actor with a single config. If you only need one signal type, the focused Actors below are easier to configure and run:

• Signalbase Real Time Funding, funding rounds only, optimized for VC deal flow and investment research.
• Signalbase Real Time Hiring, hiring signals only, optimized for sales prospecting on growing companies.
• Signalbase Real Time Job Changes, executive moves only, optimized for trigger-based outreach.
• Signalbase Real Time Acquisitions, M&A activity only, optimized for competitive intelligence.

All Actors share the same underlying data and pricing.

What data is available?

Endpoint	Description	Key fields
Funding Signals	New funding rounds as they happen	Company, round type, amount, investors, date
Acquisition Signals	Companies showing acquisition indicators and potential M&A targets	Company, signal score, indicators
Hiring Signals	Open job postings with company context	Job title, location, seniority, department, company
Job Change Signals	Executive and leadership role changes	Person, new role, company, LinkedIn URLs
Investors	VC, angel, PE, and corporate investor profiles	Firm, AUM, focus areas, check size, portfolio
Companies	Company profiles with growth data	Name, industry, headcount, growth rates, location

How to use

Run from Console or API

Select a signal type, set your filters, and the Actor will fetch matching results. The full API response (including data, pagination, and meta) is available in Output, and individual records are also stored in the Dataset as JSON, CSV, or Excel.

Example input:

{
  "signalType": "funding",
  "date_preset": "last_30d",
  "countries": "US,GB",
  "round": "Seed,Series A",
  "limit": 50
}

Standby mode (real-time API)

When the Actor runs in Standby mode, it exposes a live HTTP server. Send GET requests directly with query parameters — just like a REST API.

Available endpoints:

GET /signals/funding?countries=US&round=Seed&date_preset=last_30d
GET /signals/acquisitions?search=fintech&countries=US
GET /signals/hiring?positions=cto,vp%20of%20engineering&seniorities=c_level
GET /signals/job-changes?departments=engineering&seniorities=c_level,vp
GET /signals/investors?categories=vc,angel&countries=US
GET /companies?search=AI&employee_count_min=50&employee_count_max=500

Response examples

Every endpoint returns the same envelope: success, data (array), pagination, and meta.

FAQ

Wait, this isn't a scraper? No. Signalbase is real-time signal infrastructure. We continuously detect new events (funding rounds, acquisitions, hiring, executive moves) from across the web, verify and contextualise them, and serve them through this API. You're querying a live system, not running a scrape on each call. This is why every signal includes the original source URL, a discovery timestamp, and full company context out of the box. Running enrichments against a list of companies you care about, so you only see signals on those accounts, is only available on the direct Signalbase platform. Get in touch if you want early access.

How is Signalbase different from PDL, Crustdata, or Coresignal? Those products are databases. We're event infrastructure. They tell you what a company looks like; we tell you what just happened to it. If you need static firmographics or contact data, use a database. If you need to know that a company raised yesterday, hired a CTO this morning, or just got acquired, use Signalbase. Most serious GTM stacks use both.

Can I get webhooks, real-time delivery, or higher volume? Yes, on the direct Signalbase platform. Apify is great for evaluation and Apify-native workflows, but if you need webhooks, custom signal types, dedicated rate limits, or production SLAs, you'll want a direct plan. Production access starts with a paid pilot scoped directly with the founding team. Get in touch at trysignalbase.com to set it up.

How do I avoid paying twice for the same signal across multiple Signalbase Actors? Every signal has a globally unique signalId. If you run this Actor and also one of the focused Actors (Funding, Hiring, Job Changes, Acquisitions), deduplicate on signalId to avoid double-processing. All Actors hit the same underlying signal stream.

Can I see how many results my query will return before running? Yes. Every response includes a pagination.totalCount field showing the full result count for your filters. Run with limit=1 first to see the count, then run for real with the volume you want. This is the cheapest way to validate filters before larger pulls.

Can I use this Actor to monitor a specific company or list of companies? Yes. Use the search parameter to filter by company name, or pass company-specific identifiers (e.g. companyLinkedinUrl for job changes). For ongoing monitoring of a defined account list, the direct platform's webhook delivery is a better fit than scheduled Apify runs. Get in touch.

Rate limits

The underlying Signalbase API has rate limits. If you hit a 429 response, wait a few seconds and retry.
