If you're an entrepreneur, you've probably heard of PrivCo.
PrivCo is often considered the authority on private company financial data. The database provides coverage on more than 940,000 privately held firms, 19,000 investors, and 154,000 funding rounds, and it's one of over 100 databases that the Gast Business Library subscribes to.
Recently, PrivCo added an additional 100,000 executive contacts! They've also improved export functionality within the database, and they're continuing to add and iterate private market content for researchers, entrepreneurs, and anyone who may be digging deeper on deal multiples, angel investors, and industry insights.
PrivCo is also a great resource for looking at deal-sourcing, and should be the first stop for anyone seeking investors or related industry insights/metrics.
