Like pitchbook, but open. An open source investor/venture capital database

← Data and databases

In simple English

This tool collects information about venture capital firms and the people who work at them. It uses artificial intelligence to read websites and pull out names, roles, and contact details. You can query the data using standard database commands. The project is free to run on your own computer. It is meant for founders who want to build their own investor lists without paying for expensive commercial databases.

What it is

A TypeScript application that crawls venture capital websites, extracts unstructured details using language models, and stores them in a version-controlled database called Dolt. It acts as an open source alternative to paid directories like Pitchbook or Crunchbase.

What it is good for

Founders who want to build a custom contact list of investors and venture capital partners without paying for commercial market intelligence tools.

Good
  • Uses language models to extract structured data from messy web pages automatically.
  • Stores data in Dolt (a version-controlled database that works like Git for data), making history easy to track.
  • Provides ready-made commands to scrape specific firms or run random discovery batches.
Watch for
  • Requires an external API key for language models, which adds ongoing usage costs.
  • Setting up Node.js, pnpm, and Dolt requires comfort with the command line.
  • Web scraping is fragile and will break when venture capital websites change their layouts.
