PitchBook Built the Private Market's Memory - Now AI Wants to Read It
PitchBook spent years turning private deals into structured, searchable memory. Its next act is making that hard-won data useful wherever investors work - from Excel and CRM systems to conversational AI.
Captain
Captain is a managed retrieval-augmented generation (RAG) platform out of Y Combinator's Winter 2026 batch. It lets developers connect data sources - S3, SharePoint, Google Drive, Slack, Notion and more - with a couple of API calls, then handles the full pipeline behind the scenes: OCR, chunking, embedding, vector storage, hybrid search, and re-ranking. The company claims roughly 95% retrieval accuracy on a published benchmark versus about 78% for hand-built pipelines, and positions itself as 'the Snowflake for unstructured data.' In March 2026 it added Odyssey, a proprietary private-market intelligence dataset queryable through the same API.
Crunchbase
Crunchbase is a San Francisco-based platform that catalogs the private markets - companies, funding rounds, investors and the people behind them - and increasingly tries to predict what will happen next. Born in 2007 as a companion database to TechCrunch, it now serves millions of entrepreneurs, investors and sales teams, layering AI-driven funding and exit predictions on top of a dataset covering more than four million companies, sold through subscriptions, an enterprise API and CRM integrations.
