Signalbase Real Time Investors

A live investor dataset generated from real funding activity. Every investor here has been detected deploying capital, not pulled from a static list. New investor records appear within a minute of new funding signals, with type, ticket size, geography, LinkedIn, and website data.

19k+ active investors detected and growing every minute. Used inside data vendors, GTM teams targeting VCs, and platforms enriching investor data on funding signals.

Why this beats most investor databases

Most investor databases (Crunchbase, PitchBook, PDL) are static lists. They include every fund and angel that's ever existed, regardless of whether they've actually deployed capital recently. The result: bloated datasets full of dormant investors, mixed in with real deal-makers.

• Built from real activity, not maintained as a list. Every investor in this dataset was detected through a real funding signal. They've actually deployed capital, recently.
• Live, not static. New investors appear within minutes of new funding signals. The dataset is continuously refreshed by your own signal stream, not by a quarterly database update.
• Source-attributed by extension. Each investor links back to the funding rounds where we detected them. You can trace any record to a real event.
• Filterable by what matters. Investor type (VC, angel, PE, corporate, accelerator, family office, fund, government), country, and free-text search.

Most databases give you every investor that ever existed. We give you the ones who just wrote a check.

• VCs and founders sourcing co-investors and lead investors for their next round
• Investment research and competitive intelligence mapping which investors are deploying capital in specific sectors or geographies
• AI agents enriching funding signals with investor context for autonomous deal sourcing
• Lead generation tools targeting active investors as a buyer segment
• B2B data vendors layering active-investor data into their existing investor databases

FAQ

How is this different from Crunchbase, PitchBook, or PDL? Those are static investor databases. They list every fund or angel that's ever existed, including dormant ones. We deliver only investors detected through real, recent funding activity, generated continuously from our live signal stream. If you need the deepest historical investor archive, use a database. If you need active deal-makers right now, use Signalbase.

Why are some ticket sizes 0 or null? Ticket size data is only populated when we detect it explicitly through funding signals or public disclosures. Many investors don't publish ticket sizes, so we don't fabricate them. Filter to records with non-zero ticket size if that's important to your use case.

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

Can I filter to only specific investor types? Yes. Use categories to filter by vc, angel, pe, corporate, accelerator, family_office, fund, or government.

Can I monitor investors active in specific industries or geographies? Use countries for geography filtering. For industry-specific targeting, the underlying Funding Signals Actor lets you filter funding signals by industry and pull the investors from those results, which is a more precise way to find investors active in a specific category.

Can I get webhooks or higher volume? Yes, on the direct Signalbase platform. Apify is great for evaluation; production-grade workflows with webhooks, custom investor 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.
