Pitch the investors that back startups like yours.
Round Funded holds 111 investor organizations in Denver and Boulder next to 60,000+ investors worldwide, with the contact to reach at each, and the outreach to do it from your own inbox.
How to find the right startup investors in Denver and Boulder
Start with focus, not fame: the stage each investor takes, the sectors it backs and how many startups it has funded. Shortlist the VC firms that write checks at your stage, add the accelerators and incubators that take companies like yours, and write to each with your traction and your ask in the first three lines. An investor with many deals in your sector is a better first email than a famous name with none.
