Pro Tips

  • 01Climate tech VCs care about unit economics, not just mission. Show a path to profitability without subsidies — that's what separates fundable from unfundable
  • 02The biggest opportunity isn't new hardware — it's the software layer that makes existing clean energy infrastructure 30-50% more efficient
  • 03Start in a single geography with favorable policy (California, Texas, or Germany) and prove the model before expanding. Policy risk is real
  • 04B2B clean energy SaaS has faster sales cycles and higher margins than consumer solar products. Sell to installers, utilities, and fleet operators first
  • 05Regulatory tailwinds (IRA, EU Green Deal) create a 5-10 year window. Build now while incentives are strong — they won't last forever
