Cleantech startups are different. Especially those in the hardware category. They are higher risk, often more capital intensive requiring manufacturing and scaling support, prototype development, product validation and development. The Cascadia CleanTech Accelerator is specifically designed for BOTH early stage, hardware and software cleantech startups located in or interested in doing business in the Northwest.

We are a mostly* virtual 18-week program delivering mentorship, structured curriculum, and connections designed specifically for early stage hardware and software cleantech startups. Paricipants that successfully complete the program are eligible for additional resources and opportunities as they are available.

*currently planning 2 required in-person events in Seattle in June and September

Established in 2016, this joint program of the Cleantech Alliance and VertueLab is a proud recipient of a Department of Energy EPIC prize and grant starting in 2021.
