Pitch the investors that back startups like yours.
Round Funded holds 76 investor organizations in Seattle 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 Seattle
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.

Frequently Asked Questions
How many startup investors are there in Seattle?
The Round Funded catalog lists 76 investor organizations in Seattle: venture capital firms, accelerators and incubators. This page shows the top 50 by investments on record; the count updates as the catalog is refreshed.
How is this list ranked?
By the number of investments on record for each firm or program, then by how complete its profile is. It is a catalog ranking, not an editorial one: an investor with many recorded deals sits above a famous name with few.
How do I pitch startup investors in Seattle?
Open each investor's profile for its stage and sector focus first, then pitch the ones that match. VC firms take cold emails with traction up top; accelerators and incubators take applications through their own site. Sign up to see the contact behind each investor and reach them from your own Gmail.
Are these investors still active?
The catalog is refreshed continuously and each profile shows the investments on record. Check an investor's latest deals on its profile before you write, since focus and fund cycles change during the year.
