TESTIMONIALS

Sonia Kastner
Founder and CEO
Pano AI
"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.”

Sam D’Amico
CEO
Impulse Labs
“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.”

Carter Li
CEO
SWTCH
"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.”

Kathy Hannun
President and Founder
Dandelion Energy
“The Ad Hoc Group has been an essential partner to the Dandelion team from early in our journey. Their ability to quickly understand the regulatory and and political dynamics of our market and translate that into a focused growth plan has ensured that we have invested our precious resources on the right markets at the right time.”

The Ad Hoc Gist: Is the US Sabotaging the $250B Carbon Removal Opportunity?
Carbon removal is in temporary panic mode as the Trump administration injects uncertainty into this nascent market. It doesn’t need to be this way.
In this month’s Gist, my colleagues Annie Gilleo and Myron Lam argue why America should continue to “dominate” this market and not cede its jobs and technological advancements to Asia and Europe, and how states can step up to fill the temporary gap.

The Ad Hoc Gist: The Pentagon’s Energy Transition
While it’s been a minute since I worked in the Pentagon, I still consider myself a national security professional. After all, energy is the national security issue to which I’ve committed the better part of my career.
In this month’s Gist, my colleague Joshua Grelle and I write about how the energy transition — particularly the growing demand for electricity at home and globally — is transforming our military.
In big AHG news, in partnership with our friends at Latitude Media, we announced the launch of the Power Resilience Forum, a new industry event focused on managing threats to our electric grid. Save the date and come join us in Houston on January 22-23, 2026.

The Ad Hoc Gist: An interview with Biden’s Chief Sustainability Officer
What a difference a few months can make. We take a break from the tumult of the moment, and look back on the last four years with Andrew Mayock, President Biden’s Chief Sustainability Officer. Mayock, who left his post on January 20th, reflects on what they achieved, what might have been, and where we go from here.
In AHG news, we’re thrilled that Michael Kormos has joined us as a Senior Advisor, and Hannah McGrath and Max Davidson have joined as Associates.
