Private companies

Access detailed data on 150+ private companies including valuations, funding history, employee counts, and key investors.

Why 10x billing?

Private company endpoints are billed at 10x the standard rate. Here's why:

Proprietary data — Valuations and funding details not available from public sources
Continuous research — Data is verified and updated regularly by our research team
Comprehensive coverage — Detailed information including funding rounds, investors, and employee counts

The X-Request-Cost-USD header on each response shows the exact cost.

Use cases

Investment research — Analyze private company valuations before they go public
Market analysis — Track funding trends across industries and geographies
Portfolio tracking — Monitor private holdings alongside public investments
Data products — Build applications powered by private market data
