CPO & Co-Founder - Proptech

🌍 About Antai Ventures Antai Ventures is a Barcelona-based venture studio with presence across Southern Europe and LatAm. We partner-up and invest in the best co-founders to build global companies willing to disrupt multi-billion dollar industries. Since 2012 we have co-founded +30 companies including Glovo, Wallapop, PlatanoMelon, and Piper . Our ventures have raised more than $1.5B in funding, have generated more than $3B in shareholders value and currently employ more than 3000 people. 💡 About the venture We are building an AI-native platform for the real estate sector in Spain — one of the most fragmented, relationship-driven, and underdigitised industries in Southern Europe. We have a validated product thesis, a clear go-to-market, and we're now looking for a co-founder that will act as Chief Product Officer. 🎯 What you’ll do Build, launch and scale a disruptive product from scratch. Own the product vision, leading the strategy, proposition, and roadmap. Talk to customers relentlessly — turn qualitative insights into product decisions. Define and prioritise what gets built, in what order, and why. Drive a culture of excellence through continuous delivery, rapid experimentation, and customer-obsessed iteration. 🔍 What We’re Looking For Proven track record as a product leader in an early-stage environment — whether as PM, Head of Product, or founder. Hands-on builder. You prototype fast and turn ideas into working features in days, not weeks. Practical AI experience. You have built production systems with LLMs — agent orchestration, multi-agent workflows, conversational AI — and know what actually works outside a demo. Product instinct. You've talked to customers, made hard prioritisation calls, and know how to build the right thing, not just build things right. Ownership mindset. You take responsibility for outcomes and think long-term about product and company value. Clear communicator. You can explain technical trade-offs to engineers and non-technical co-founders alike. Fluency in Spanish and English. 🤝 What We Offer Day-1 founding seat. Join an ambitious venture from the ground up, with a validated concept and Antai's full backing. Significant equity. Own a meaningful stake in the venture, plus optional carry in other Antai portfolio companies. Full-stack operator support. Access Antai's expert teams in Product, Engineering, Design, GTM, Legal, Talent, and Fundraising whenever you need them. Founder community and investors. Join a tight network of serial entrepreneurs and top-tier backers who have scaled category leaders. Based in Barcelona, hybrid.
