Calling all clean energy startups! Tumml is looking for entrepreneurs to apply for the Urban Clean Energy Prize – a three-month program where we will support startups with clean energy solutions for our cities. The program will run from September 19 – December 16, 2016, and the selected startups will each receive:

  • A $15K grant

  • Hands-on consulting services and mentorship from the Tumml team and Mentorship Board to help you pilot (or expand) your product/ service within a municipality

  • Free office space in downtown San Francisco through the duration of the program (if desired)

We are interested in startups advancing renewable resource adoption and efficiency in urban areas – water, solar, wind, green building materials, etc. Renewable resources are critical to the future of our cities, helping us to: reduce greenhouse gas emissions from our power and transportation sectors; achieve better health outcomes because of lowered air, water, and land pollution; encourage responsible relationships with natural resources; and support community energy resilience. 

We are currently reviewing applications. Thank you for your submissions!
