Leadership resources and insights

200+ Conversations on Growth & Optimization

Through CRO.CAFE and other podcasts, I've explored the psychology of user behavior, experimentation culture, and what makes digital experiences succeed. These conversations with industry leaders and practitioners surfaced patterns I now apply to building resilient developer ecosystems. The same question runs through both: how do people actually behave, and how do you find out?

From Optimization to Ecosystem Thinking

My focus has shifted from hands-on conversion optimization to strategic thinking about tech ecosystems and technology choices. Explore insights on behavioral psychology in tech, building resilient systems, and why I care deeply about open source, privacy, and developer sovereignty. More content coming on antifragile ecosystem design.

Speaking on Community, Technology & Human Behavior

Keynotes at 50+ conferences across 25 countries, sharing what 20+ years at the intersection of psychology and technology has taught me. Topics range from developer community building and open source ecosystems to behavioral design and the future of tech communities. Available for strategic discussions on building resilient developer programs.

Strategic Impact

Transform your ecosystem into a strategic growth engine

Community Building & Strategy

I build community functions - the strategy, the systems, and the teams to run them. By combining psychological insights with strategic technology choices, I help organizations build ecosystems that strengthen under pressure, reducing support costs while accelerating platform adoption.

Executive Advisory for Developer-Led Growth

I guide C-suite leaders through the shift from product-first to community-first strategies. My psychology and experimentation background keeps the focus on what can be tested rather than assumed, so the calls that shape market positioning are grounded in evidence, not hunches.

Organizational Transformation

I help companies restructure around community-led growth, aligning engineering, marketing, and business development for ecosystem success. This includes designing measurement frameworks, incentive models, and cross-functional processes that scale community impact without proportional resource increases.
