Cleantech Open Northeast Accelerator Program Hosts First In-Person Regional Finals Since 2019

Somerville, MA --September 20, 2022 -- Featuring some of the most innovative climate economy startups from the Northeast, Canada and around the world, Cleantech Open Northeast (CTONE) will be hosting its 2022 Regional Finals Awards and Showcase 29th at Greentown Labs in Somerville, MA. CTONE is the Northeast division of Cleantech Open, the world’s largest cleantech accelerator. More than thirty startups from this year’s cohort will take part in the showcase, and six finalists will pitch publicly and compete for $60,000 in cash prizes. The finalists will be selected during the private Regional Semi-Finals on September 28th, hosted by Foley Hoag at their offices in Boston’s Seaport.

Beth Zonis, Senior Director, Cleantech Open Northeast commented: “After two years of virtual regional finals events, we can’t wait to celebrate the accomplishments of this year’s cohort! We are looking forward to bringing together diverse stakeholders from across the local cleantech innovation ecosystem and to let them inspire us with hope for the future of the environment.”

The 2022 Cleantech Open Northeast alumni cohort provides solutions across energy efficiency, generation, distribution and storage as well as green building, transportation, smart cities, agriculture, water, waste, chemicals and advanced materials, and information and communications technologies. The companies come from Connecticut, Maine, Massachusetts, New Jersey, New York, Pennsylvania and Rhode Island and also represent international locations including Canada, Germany, India, Nigeria, and South Africa.

Johannes Bochdalofsky, CEO of SeaH4, a startup in the 2022 cohort, stated: “No matter what comes from the pitching competition, the knowledge we acquired throughout the mentoring sessions, webinars, workshops, and everything else, along with our association with CTO as soon-to-be alumni, already has us feeling like winners.”

More than 45 expert judges – mostly from around the Northeast, and including some from as far away as California and Texas – will assess thirty-two teams and select the six finalists. They will review the startups’ deliverables for the Cleantech Open accelerator and listen to the investor pitch presentations during the private semi-finals on September 28th. The six finalists will pitch to a judging panel of top cleantech and business leaders, including Aly Bryan of Closed Loop Partners, Hilary Flynn of the Massachusetts Clean Energy Center (MassCEC), David Miller of Clean Energy Ventures, Bala Nagarajan of NextEra Energy, Carlos Nouel of National Grid, and Ryan Taylor of Azolla Ventures. Joe Curtantone, President of NECEC; Hillary Flynn, Managing Director of Investments at MassCEC; and Ken Hayes, Executive Director of Cleantech Open, will also deliver keynote speeches during the regional finals event.
