🌍 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.
