How to raise in Seattle
- Map the local ecosystem first: accelerators, university venture programs, angel groups and the founders who raised here in the last two years.
- Ask every local founder you meet one question: which investor was most helpful, and would they introduce you?
- Pair local checks with a few out-of-town funds that back your sector; a local lead makes national investors more comfortable.
- Read the pre-seed without a network playbook.
About this data
Counts are records in the Zalarma investor database, as of 2026-11-01: angels, venture firms and their partners, micro-VCs, family offices, corporate VCs and accelerators that list startup investing. One investor can appear in several stage or sector rows. Stage, sector and check size come from what each record lists, so not every record has every field. Counts under 10 are not shown. Firm names are listed; we do not publish personal contact details on this site. Read how we build and check the data.
