Fighting climate change
one startup at a time.

We help climate tech startups

Climate tech startups operate in complex, highly-regulated markets. The Ad Hoc Group helps early and late stage startups translate policy and regulatory insight into business returns, design and execute go-to-market strategies, and source and close deals.


The startups we work with are solving the toughest climate challenges.

Here are our past and present clients.

"We wouldn't be where we are without The Ad Hoc Group team. They were instrumental in helping us understand our market and its regulatory drivers, refine our product offering and messaging, and close our first deals. Rather than arms-length advisors, they have been part of the Pano team from nearly day 1.”

“Working with The Ad Hoc Group has been a great experience. They were super clutch when it came to closing a Series A in the difficult funding environment of 2022. They helped us get deals over the finish line by highlighting important policy tailwinds to investors, presenting complex information in an immediately understandable way.”

"The Ad Hoc Group developed an intimate knowledge of our business, our team, and what we needed in our first head of policy role. They then helped us hire an excellent leader, supported him as he hired additional members of the team, and then helped onboard them. They bring a lot more than recruiting to the table; they've actually done these jobs themselves so knew what we needed from the inside out and then set up our new hires for success.”

The Ad Hoc Gist: Geothermal, It’s So Hot Right Now

Geothermal technology is getting a lot of attention lately. There are essentially two types: geothermal power and geothermal heating and cooling. The former can deliver clean power 24/7, while the latter can heat and cool buildings super efficiently.

We enlisted two experts, Joselyn Lai, CEO of Bedrock Energy, and Michael Campos, investor at Energy Impact Partners, to help us understand the enthusiasm, challenges, and bold predictions for the future of geothermal technologies.
