Our investors and partners don't just provide funding, they also provide opportunities for pilot tests, proof of concept programs, large challenge prizes, and, also included, advice as to how emerging startups should position themselves to best work with funders to secure the financing they'll need to grow.

Note that Cleantech Open is neither a fund, investor, broker, nor finder and is simply arranging introductory meetings between startups and investors / partners. CTO does not take a commission, equity, nor a piece of any deal that may result from these meetings, nor does CTO have financial positions in any of these companies. 

Shoutout to the team of finance and engineering volunteers, led by long-time CTO volunteer and mentor Josh Schein of GK Advisors.  

Much appreciation to the volunteer interns and developers of our sophisticated matching tool:
Nathan Destouches (2020-2024), Amruta Joshi (2022-2023), Anthony Song (2020), Olivia Victorino (2020) and Heeju Son (2020-2021).

Thank you!
