Lars van der Meer thrives in the intersection of data and human behavior. As a Growth PM at Amsterdam's Adyen, he obsessively tracks how small UX tweaks affect conversion rates, often running A/B tests late into the evening. His cycling commute through Amsterdam's canals gives him time to mentally model cohort behaviors - he's known for catching flawed assumptions in meetings with a polite but firm 'Let's check the data on that.' While colleagues chase viral growth, Lars advocates for sustainable scaling, a philosophy shaped by seeing too many startups flame out during his time at Booking.com. On weekends, you'll find him analyzing his Strava metrics with the same rigor he applies to product funnels.
