The short answer
Our database lists 92 startup investors in Washington focused on climate & energy — 12% of the 758 startup investors we list in the state. Most are in Seattle (69). (Zalarma investor database, as of 2026-11-01.)
What these investors look for
- Separate the technology risk from the market risk, and show what has been proven in the lab, at pilot scale and with a paying customer.
- Non-dilutive capital (grants, utility programs, state energy offices) stacks well with angel and seed rounds; investors like seeing it in the plan.
- Corporate investors from energy, utilities and industrial companies can be the first strategic check and the first customer.

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 Firm names are listed; we do not publish personal contact details on this site.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.
