Cleantech Open 2026 Tri-Valley Kick-Off Event

We will share information about Cleantech Open's (CTO) upcoming 2026 Accelerator Program! At CTO we are the world's oldest and largest Clean Technology Startup Accelerator. We've had ~2,100 early stage startups successfully graduate our program since 2006. This time of year, we're looking for ambitious and innovative entrepreneurs that are trying to solve some of the world's greatest problems who are looking to grow their business to the next level using our proven curriculum.

It's a 12-week program starting in June and running through August, with a final competition in September and Culminating Event in October. By the time you're through CTO, you'll have everything you need to pitch to early-stage investors and Climate VCs. Each startup will be assigned at least one mentor to help the startup succeed in the program and progress the company. We work with startups that have raised <$2M in equity, all the way down to trying to flush out an idea on the back of a napkin. If you're serious about your business, then we are here to help!

We are also always looking to expand our mentor and other volunteer participation.

Get the chance to share your idea/company with the audience, if you'd like.

Meet Alumni, CTO Staff, Mentors, and other people from the Bay Area Cleantech Community as we get together to meet and mingle. All are welcome!

We'll have some light food available as well!

NOTE - About $10 Quality Assurance RSVP fee: All CTO Events have a $10 Quality Assurance RSVP fee to discourage no-shows and encourage maximum engagement. If cost is an issue, please contact Ryan Hoover at [email protected] and we can work something out.
