How to Pick Winners for a Climate Tech Portfolio

Hans’ message to fellow investors is simple—and counterintuitive:

“Venture capital isn’t about picking winners. It’s about avoiding mistakes.”
Hans Dellenbach, CFA, Partner & CFO, Emerald

We’re not in the business of predicting the future.

We’re in the business of asking the right questions.

  • Is the product-market fit truly validated?
  • Is the customer value proposition clear—and financially sound?
  • Is the team equipped to navigate this industry?
  • Can we see a viable path to return?

When we don’t get conviction-level answers, we pass.

Not because the founder’s dream isn’t compelling—but because capital discipline matters.

As Hans puts it, strong portfolio performance isn’t driven by finding unicorns. It’s about building a resilient portfolio where the majority of companies return capital—or better. And where failure is the exception, not the norm.
