Investing with Conviction: Real stories from Asterion Ventures & Plastic Odyssey

This session is intended for impact investors, operators, and leaders actively involved in deploying capital or building climate and ocean solutions.DescriptionWhat does it look like when impact actually works? Not in theory, but in practice. Some models are venture-backed. Some are funded by global institutions and built through partnerships on multiple continents. Some do both at once. This evening, we're sharing the stories where financial performance and positive impact didn't have to choose sides.Fabien Lamaison, Executive Director of Plastic Odyssey Fund, will share insights from Plastic Odyssey’s 3.5 year expedition across 30 countries confronting ocean plastic pollution and supporting solutions in coastal communities by blending nonprofit mission with for-profit mechanics. Fabien will also outline the organization’s next bold missions and vessel to restore biodiversity in UNESCO Marine World Heritage sites.Diana Khramina, Venture Partner at Asterion Ventures, will share success stories from the fund's portfolio, showing how backing climate and impact companies generates returns while driving measurable change for people and the planet.

Different models. Different structures. Same conviction that planet, purpose, and profit can belong in the same sentence.This intimate evening brings together a handpicked group of 20-30 investors and operators around multiple stories of action over talk. Small enough to talk, curated enough to make every conversation count.Agenda5:00 PM / Doors open
