OpenAI is an AI research and deployment company dedicated to ensuring that general-purpose artificial intelligence benefits all of humanity. AI is an extremely powerful tool that must be created with safety and human needs at its core. OpenAI is dedicated to putting that alignment of interests first — ahead of profit. To achieve our mission, we must encompass and value the many different perspectives, voices, and experiences that form the full spectrum of humanity. Our investment in diversity, equity, and inclusion is ongoing, executed through a wide range of initiatives, and championed and supported by leadership. At OpenAI, we believe artificial intelligence has the potential to help people solve immense global challenges, and we want the upside of AI to be widely shared. Join us in shaping the future of technology.

OPRTRS is an operator-led investment platform backing founders at the very beginning. We’re powered by 170+ top tech operators who know how to ship, scale, and survive the early chaos. We believe operators build the best companies and support each other better than any boardroom ever could. So we’ve turned that conviction into a community: a network of current and former leaders from OpenAI, Palantir, Stripe, Mistral AI, Qonto, Revolut, Datadog, Doctolib, Hugging Face, Wiz, Rippling, Backmarket, and dozens more. We invest €200k in the first rounds and surround founders with hands-on operator support: GTM, product, hiring, internationalization, fundraising. No theatre, no fluff. Just people who’ve done the work. Our core team: Christophe Raynaud (Cofounder @ ISAI) Noé Gersanois (ex-Partner @ Raise) Younès Rharbaoui (ex-Partner @ The Family) Supported by Renaud Boutet (SVP Product @ Datadog) as Venture Partner. We’re backed by great partners: Leblon Capital, Kima Ventures, Motier Ventures, Financière Saint-James - who trust us to spot and support the next generation of breakout operators-turned-founders. Since launching in 2024, we’ve already backed 15 ambitious teams, from deep tech to AI to industrial innovation. What matters to us isn’t the sector it’s the ambition and the builders behind it. If you’re an operator making the leap, or a founder who values hands-on expertise over PowerPoints, we’d love to meet you: hello@oprtrs.club
