Climate Seedstrap Program - Third Sphere

Call for Climate Tech Founders Who Just Won’t Give Up

“Be fearful when others are greedy, and be greedy when others are fearful.” — Warren Buffett

It’s never been a better time to build a startup, and we’re very interested in working with more founders in a new model for building: seedstrapping. We’ve quietly been encouraging this trend, but now we’re ready to lean all the way in. More on why we think seedstrapping is the new Plan A for company building in our Seedstrapping playbook.

Why is it a great time to build a climatetech startup? Yes there are less resources; less investors able or willing to invest, less consultants, less events — but all of this means there are less distractions too. Additionally, with AI and automation tools, there’s never been a more efficient tech stack and more pathways to build a successful company.

Yes there is more confusion; “what’s going on with tariffs, grants, consumer and business spending, and climate action commitments?” — but this means that true market signal is more important and clear than ever.

There are also fewer founders getting in or staying in the effort to build startups. That’s fine. We’re very interested in working with the folks who despite all of this want to jump in the frey, or stay in and find a way.

What are we offering?

  1. A very fast decision, clear terms, and strong, reputation backed, commitment to helping you succeed.

  2. Leverage on everything we’ve built and learned over our 10 years building TS and over 20 years building and supporting tech companies before that.

Here’s what that looks like in practice:

With more to come including marketing and founder led sales automation.
