OneRagtime is a venture capital fund built as a platform. We source, fund and support early-stage European tech startups, and we run the entire investment process on tools and technology we build ourselves.

Since 2017, we've invested in 53+ startups, delivered 9 exits and backed two unicorns. We're powered by a community of 500+ investors. The team is 12+ people from 6 nationalities, based in Paris and Barcelona.

We believe technology combined with collective intelligence beats size. That belief is operational: our internal platform, Core Intelligence, runs sourcing, analysis, portfolio tracking and investor relations, and our team ships features in days by directing AI agents rather than in months of manual development.

The role

You are our AI champion. Embedded in the investment team, you use AI to accelerate three things: how we work, what we invest in, and how our founders build.

Within the fund. Our Investment, Finance & Legal, and Investor Relations teams run on workflows that can be automated. You spend time with them, you spot the friction, you ship the fix.





On our deal flow. AI shows up in every deck we get. You help us tell a real technical edge from a nice AI wrapper, and you build the sourcing engine that surfaces the best companies before their round.

With our founders. 50+ portfolio companies are rethinking their product and operations around AI right now. You're the person they call for a second opinion.

The role is deliberately hybrid. You code every day, and part of your week goes into investment discussions, due diligence, and conversations with our founders. If you're thinking about starting your own company one day, this is a front-row seat to see how 50+ companies raise, build, and scale.

You report directly to Stéphanie, our CEO, and you work as a pair with Fortune, our crack full stack developer based in Barcelona. Fortune's energy goes into building. As Tech Lead you bring the complementary half: product direction, the conversations
