Jonathan Userovici is a General Partner at Headline who built his investment approach by spending his first 100 founder meetings reverse-engineering how partners made decisions, developing pattern recognition for exceptional teams through what he calls an unusually structured apprenticeship approach. He has created a detailed, data-driven public playbook specifically for Series B fundraising that includes concrete benchmarks and positions this round as the last milestone before proving cash is the limiting factor—a level of operational guidance that's relatively rare from European VCs.

• Deep passion for the maturation of the French and European tech ecosystems. Frequently celebrates regional success stories and highlights how rapidly the local market is scaling. A notable example includes praising the startup Swile for hitting a massive revenue milestone and achieving centaur status, while also pointing out that Paris recently topped the charts for European venture funding.
• Advocating for aggressive investment in sales and marketing teams. Points out that European founders often underinvest in this area compared to American companies. Used Snowflake as a benchmark to illustrate this strategy, observing that exactly half of their total workforce is dedicated purely to sales and marketing.
• An understanding that building generational companies requires patience and follows a non-linear growth path. Illustrated this by sharing the trajectory of Roblox, noting that it took the company six years to increase its valuation tenfold to half a billion, but less than a year to multiply it tenfold again past sixty billion.
• Strong interest in foundational technology layers, specifically artificial intelligence applications and application programming interfaces. Highly enthusiastic about AI tools that are already successfully running in production, referencing live demonstrations at companies like Mirakl and Front. Additionally expressed a direct desire to back founders who are building new business enablers, especially those creating new payment formats.
