CleanTech Open 2024: Maine Launch

Come join E2Tech and NECEC at the UMaine Portland Gateway for an evening of food, drink, celebration and opportunity!  

Learn how the CleanTech Open accelerator program can help you develop your venture and how to apply to participate. Since 2005, more than 70% of Cleantech Open's reporting alumni companies nationwide are still active and have collectively raised over $2B in external funding.

We welcome entrepreneurs, students, investors, savvy technologists, and those interested in joining our growing cleantech community in Maine. E2Tech has been a partner in this initiative since 2013, and participation fees for Mainers in CleanTech Open Northeast can be covered by Maine Technology Institute!


  •  About Cleantech Open Northeast - meet the team and learn about opportunities to be involved. 
  • Also brief comments from Eric Howard, E2Tech's Executive Director and Susan Morris, honorary consul of Canada in Maine.
  • Alumni Lightning Talks - hear from Cleantech Open Northeast alumni about their experiences in the program.
  • Entrepreneur Introductions - certain firms will present their clean technology & business. To participate in this part of the program, please sign up when you register!
  • Q&A - ask your questions about the program, application process, and more.
  • Networking - meet people in the local ecosystem who are interested in and support Maine cleantech entrepreneurs in a wide variety of ways.

For background, see the Cleantech Open Northeast 2023 Impact Report or watch this four-minute video. Both from Maine, Amply Energy was the 2023 Northeast Regional Winner, and Shred Electric was a 2023 Northeast Regional Finalist.

Please register early.  $10 for E2Tech and NECEC members, free for CleantechOpen 2024 Prospective Startups, Cleantech Open Alumni and Mentors, and Program sponsors as well as students. Please email to be registered under a special category. If you've got a world changing idea, don't let cost be a barrier to attendance. Registration is capped at 100 attendees and we may reach capacity.

The UMaine Portland Gateway at 500 Fore Street also serves as the temporary home of the Maine Law School. Parking is available across the street at the Custom House Parking Garage, and street-side parking on many nearby streets is free after 5 pm.
