We’re building a market where credits are strategic climate tools that buyers want to engage with.Combining rigorous science with optimism to drive real impact.The carbon market today faces a paradox.
Companies demand high‑integrity credits, backed by science and transparency. Yet, they often struggle to find credits that are relevant, meaningful, and traceable to their business activities.
At Rainbow, we’re aligning both sides of the market by certifying projects that directly reflect buyer’s strategy operations, and impact priorities.FoundersLudovic ChatouxChief Executive OfficerLinkedinClément GeorgetChief Product OfficerLinkedinGrégoire GuiraudenChief Operations OfficerLinkedin
