Extantia Capital runs a dual-strategy ecosystem builder model where their Flagship fund invests directly in early-stage climate tech startups while their Allstars fund backs other climate-focused venture funds, giving them visibility across more than 160+ companies. They use an internal EPIC methodology with a dedicated Head of Carbon Math to estimate each startup's potential carbon savings by 2050 and set quantitative impact targets, focusing on backing technologies that create green discounts rather than green premiums.
