A New Approach to Energy Storage | Thomas Nann, Founder & CEO @ Allegro Energy

Bringing a cleantech solution to market is one of the hardest problems in climate innovation. The technology might work. The mission might be urgent. But without the right commercial strategy, even the most promising companies stall out before they reach scale.
That tension is why go-to-market keeps coming up on The Grove. Across conversations with founders and operators building everything from novel energy storage systems to next-generation grid infrastructure, the same questions surface: How do you sell into slow-moving industries? When do you chase enterprise contracts versus building a consumer base? How do you price something the market has never seen before?
In episodes like our conversation with Thomas Nann of Allegro Energy, these questions move from abstract to concrete. Founders share what actually worked, what they got wrong early, and how they think about timing, partnerships, and customer education in markets that are still forming.
If you are a founder figuring out your first commercial motion, an investor evaluating a team's market thinking, or a climate professional trying to understand how cleantech companies build traction, this collection of episodes offers direct insight from people doing the work. No generalizations, just real conversations about the specific challenges of selling solutions that the world needs but has not yet learned to buy.
