OpenDecide's mission is simple: make best-in-class team performance achievable at the speed modern business demands. Founded in 2019 and headquartered in Paris (Station F) and Toulouse, we saw a fundamental problem: organizational science has decades of validated research on what drives team performance—but it was locked in academic papers and expensive consulting engagements. We built an AI platform that changes that: combining a century of organizational research with continuous guidance to help teams reach proven, best-in-class performance in weeks, not quarters. Today, 3,500+ leaders across 50+ companies in banking, luxury, and industrial sectors use OpenDecide to turn team effectiveness into competitive advantage. We're researchers, engineers, and builders united by relentless focus, deep thinking, and a passion for creating technology that produces measurable impact on how teams execute. We don't build coaching theater—we build performance systems that show up in your numbers.
