About this episode

Sébastien Léger's path to venture capital began with nearly two decades at McKinsey, advising on cleantech and building decarbonization scenarios. Around 2020, driven by curiosity about the "next 40%" of technologies not yet at economic parity, he shifted focus toward startups. This exploration led to the co-founding of Slate Venture Capital, alongside two seasoned entrepreneurs and another investor, with a mission to fund and support the next generation of climate innovators.
