“It’s just incredibly humbling, to say the least. The corporate partners and the mentors of the DeltaClimeVT program have been incredibly generous with their time. I’ve never experienced anything like that. Everyone said yes to having a conversation. And then they were very candid about providing feedback, even if sometimes it wasn’t always the feedback you wanted to hear but it helps make your company better and it helps make you develop a product that’s better so that’s been incredible. We’ve been in a few accelerators – this has been the best by far.”

Aimee Gotway BaileyFounder & CEO, Rock Rabbit, Energy 2024 Winner

“This is the best accelerator that we have participated in. Specifically, this program has a unique curriculum that’s designed to create a collaborative competition and allow us to sit across the table from electric utilities, planning directors and CFOs.”

Marcelo SandovalCo-founder, CEO, Chief Scientist, ProsumerGrid, Energy 2023 Winner

 “The DeltaClimeVT program is unique because sponsors are actual customers that are looking to fund pilot projects. The learning that we garnered from our cohort peers was invaluable and the resulting friendships will be long-term. The curriculum from ecosVC has equipped us with tools that we will continue to adapt as we move from lab to pilot to commercialization. We are grateful to VSJF for allowing us to participate.”

Thor JensenHalitra, Energy 2022 Winner

“I can’t recommend this program enough for early-stage pre-seed/seed entrepreneurs. With a small (highly focused) cohort, phenomenal facilitators with decades of experience, and people who truly care about helping to advance your startup in a meaningful way, DeltaClimateVT is an unparalleled program in the accelerator space.

Vermont offers entrepreneurs the opportunity to access services, networks and growth capital, in a state known for its high quality of life. Vermont was recently ranked the #1 state to move to thanks to growing professional opportunities. In-person DeltaClimeVT sprints are held in Burlington, the state’s largest city, which sports a vibrant entrepreneurial ecosystem supported by:

  • innovative companies willing to pilot new, groundbreaking products and services
  • growing incubation and co-working infrastructure
  • an active lending and investment community
  • like minded companies eager to help and partner
  • regular entrepreneurial meetups and events
  • robust technical and professional services
  • multiple higher educational institutions

The undesirable fact that climate change will have a large effect on the way we all live our lives and how we interact with each other has created an opportunity for innovative entrepreneurs to develop products and services that aim to mitigate the risks and deal with the consequences of climate change.
