About Climate Capital Stack

The inception of Climate Capital Stack was prompted by startups raising equity from venture capitalists for the wrong reasons—usually in place of equipment finance. 

Raising equity is not always the best option for hardware startups, but early-stage startups have limited access to non-dilutive options. Additionally, businesses that may be eligible for non-dilutive options are unaware they can pursue them.

Climate Capital Stack aims to educate founders, map the ecosystem, and help bridge connections.

There are a few questions that Climate Capital Stack seeks to answer: 

  • How can we finance higher-risk emerging technologies? 

  • How can we help middle-stage companies that are often overlooked?

  • How can we mainstream climate financing?

Miela is a Venture Partner at Third Sphere investing in seed stage climatetech for mitigation, resilience, and adaptation – with a soft spot for near-future sci-fi that doesn’t depend on regulations, altruism, or 10+ years of science risk. She sees climate as a physical challenge requiring physical solutions, and scaling hardtech as benefitting from an expanded capital stack – so she’s focused efforts over the last 4 years on hardware investing and mapping out non-dilutive capital sources to help climate tech founders navigate the credit landscape and other alternative funding mechanisms.
