The Climate Founder’s Toolkit: Building the Right Capital Stack and Commercial Path in 2026

What does it take to build a scalable climate company when the old fundraising playbook no longer works? Where do you find the capital and customers that will get you there?

The climate tech operating environment has fundamentally shifted. Climate-focused VCs are fewer and further between, fundraising cycles are longer, and founders are increasingly stranded at the seed to series A or series A to B gap. But the capital and customers are there – they’re just not where most founders are looking. GigaClimate Founder & CEO Nick Halla, alongside a curated bench of founders and capital allocators, will host discussions and workshops centered around two  frameworks every climate founder should be running today: the Climate Capital Stack and the Beachhead-to-Gigaton Path. Attendees will leave with a capital stack canvas and a beachhead hypothesis ready to pressure-test.
