Build a deal sourcing
tool to find, enrich
& monitor founders.

Crustdata’s APIs detect and deliver the earliest signals of new founders and startups.

From title changes to stealth announcements and detailed people history, we help your team be first to reach the right founders.

Why leading VC funds are
rebuilding sourcing internally

The problem

Our solution

Everyone sees the same founders at the same time on PitchBook, Harmonic, or Spectre.

With our Real-Time Search API and Watcher API, you instantly see every founder who matches your criteria the moment they appear not weeks later.

Existing platforms were built for data on more established startups, not early stage startups.

Our Watcher API notifies you of early signals such as job title change, stealth company job change, first hires, social posts - the data that actually matters for early stage sourcing.

Existing platforms don’t surface growth signals instantly, resulting in missing potential investment opportunities.

Our Real-Time Enrichment APIs and Watcher API crawls the web at the moment of request to find the most up-to-date information and signals.

Scrapers and in-house pipelines break constantly, wasting engineering resources.

We power 200+ customers with large volume needs. Our APIs are built to be robust and provide structured, always-fresh people and company profiles.

VCs are unable to exploit their edge by codifying their thesis due to limited filters and lack of reliable data on existing platforms.

We give you raw, unbiased, exhaustive data so you can build your own thesis-driven filters without external influence.
