Signalbase Real Time Companies Dataset

A live company dataset generated from real signal activity. Every company here showed up because we detected something happening — funding, hiring, leadership change, M&A, or other signal. They're not static entries pulled from a registry. They're companies in motion, with industry, headcount, country, founded year, LinkedIn, description, and metadata.

189k+ active companies detected and growing every minute. Used inside data vendors, GTM teams, AI agents, and platforms that need company data filtered by real activity, not just existence.

Why this beats most company databases

Most company databases (Apollo, Clearbit, Crunchbase, ZoomInfo, PDL) give you every company that exists, regardless of whether anything is happening at that company right now. The result: bloated TAM lists where 50% of records are dormant or dead leads.

• Built from real activity, not maintained as a list. Every company in this dataset was added because we detected a real signal — funding, hiring, executive change, M&A activity. They're alive and showing signs of motion.
• Live, not static. New companies appear within minutes of new signals surfacing. The dataset is continuously refreshed by your own signal stream, not by a quarterly database update.
• Source-attributed by extension. Each company links back to the signals that surfaced it. You can trace any record to a real event.
• Filterable by what matters. Industry, country, employee count, founded year, free-text search.

Apollo gives you every company that exists. We give you the companies actually doing something.

Built for

• B2B sales and outbound teams building TAM lists of active companies, not importing dead leads from Apollo
• AI SDR and GTM platforms enriching pipeline with signal-derived company context
• B2B data vendors layering "active companies" as a quality filter on top of their existing databases
• Lead generation tools sourcing fresher, more dynamic company data than static directories
• AI agents building autonomous research, prospecting, or competitive intelligence workflows
• Investment research tracking which companies are actively raising, hiring, or expanding in specific sectors

This Actor delivers the company dataset. If you want the live signals that generated it, or other data types:

• Funding rounds that surfaced these companies → Signalbase Real Time Funding
• Executive job changes for trigger-based outbound → Signalbase Real Time Job Changes
• Hiring signals for prospecting on growing companies → Signalbase Real Time Hiring
• M&A signals for competitive intelligence → Signalbase Real-Time Merger & Acquisition Signals
• Investor profiles generated from funding activity → Signalbase Real Time Investors
• All signal types in one Actor → Signalbase API

All Actors share the same underlying signal stream, deduplicate on signal IDs if you run multiple. Pricing varies per Actor based on data type and use case.

Pricing

This Actor uses pay-per-event pricing. Each successful API call is charged as one api-call event. Failed requests are not charged.

FAQ

How is this different from Apollo, Clearbit, Crunchbase, or PDL? Those products give you every company that exists, regardless of activity. We deliver only companies detected through real, recent signal activity (funding, hiring, M&A, leadership changes), generated continuously from our live signal stream. If you need the broadest possible company database, use Apollo or PDL. If you need an active, motion-filtered company list right now, use Signalbase. Most serious GTM stacks use both.

Why do some company records have null fields like website, foundedYear, or growthInfo? We populate fields only when we have verified data. We don't fabricate values to make records look complete. Use the filter parameters to narrow to records with the data you need (e.g. founded_year_min excludes companies with null founded years).

How fresh is the data? Companies are added or updated continuously as new signals surface. New company records appear in the API within minutes of the signal that generated them.

Can I filter to companies by signal type that surfaced them? Not directly via this Actor — this is the unified company dataset. To filter by signal type (e.g. only companies that recently raised funding), use the relevant signal Actor and pull company data from those results. For example, the Funding Signals Actor returns funding rounds with full company context, giving you only companies that just raised.

Can I monitor specific companies or industries? Yes via search, industry, and countries. For ongoing monitoring of a defined account list with webhook delivery, the direct Signalbase platform is a better fit than scheduled Apify runs. Get in touch at trysignalbase.com.

Can I get webhooks or higher volume? Yes, on the direct Signalbase platform. Apify is great for evaluation; production-grade workflows with webhooks, custom enrichment, and dedicated rate limits live on the direct plan. Production access starts with a paid pilot scoped directly with the founding team. Get in touch at trysignalbase.com.

Rate limits

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