AI Data Center Boom Dominates Climate Week, Splitting Founders

Climate tech venture deal value has risen for four consecutive quarters and topped $14 billion in the first quarter of this year, according to the most recent available data from PitchBook. That figure framed this year's New York Climate Week, where the AI infrastructure boom took center stage — and not everyone welcomed it.

Much of the climate tech community is riding the AI wave alongside the rest of the U.S. economy. Some founders have reservations about the sheer number of natural gas power plants being built to feed AI data centers. But because many climate tech startups are energy-focused or energy-adjacent, the buildout has been embraced as an opportunity to carry companies through the valley of death.

The singular focus carries a cost. Some promising sectors risk being overlooked.

The pattern extends a trend that has built over the last year. As climate tech companies struggled to secure financing — either because of canceled federal grants or investor hesitancy — those that could rework their pitch to match the AI mania did exactly that.

The pivot has worked. It is the best fundraising environment for climate tech in several years, with most of the deal value driven by sectors boosted by data center construction: the built environment, grid infrastructure, and dispatchable energy that can be switched on or off when needed.

It is an opportunity few have wanted to pass up. One exchange during a panel at New York Climate Week captured the moment. Two founders, asked whether they would prefer the AI buildout to proceed at its current pace or at a more climate-responsible speed, said without hesitation that faster was better. Both of their startups were in energy.

Not everyone agrees. Several founders said the data center boom was distracting from other promising segments of climate tech, including ventures that were hitting their targets without leaning on AI hype.

"Corporates are still interested in climate," one founder said. The difference today is that large companies do not want to publicize it, mostly for fear of drawing the Trump administration's ire.

There were also signs the AI boom is beginning to wear thin. Three years ago, money for scaling was hard to find, even for startups showing promising results. Now customers are clawing their way into demos. "Where was this money three years ago?" drew knowing eye rolls from more than a few people asked that question.

That is the world they live in now, founders acknowledged. The smart entrepreneurs are all finding ways to meet customers where they are.

The undercurrent at New York Climate Week was that the data center party will not last forever. But it might last long enough to help startups build durable businesses — after which they can refocus on the carbon-cutting mission they were founded to pursue.
