Hi, I'm Stephan. My work has 700K+ App Store ratings, a 4.5 score, multiple 'Award' wins, and reaches 20+ million people everyday.

"Why UX Bottlenecks?"

Most product teams are drowning in feature requests. Everyone has an opinion. Nobody can agree on priorities.

The real problem? You've lost sight of the critical paths — the 2-3 journeys that actually drive revenue and retention.

Those journeys have bottlenecks. Small friction points that seem minor but compound into massive losses: onboarding drop-off, support volume, silent churn.

I find those bottlenecks. I measure their impact. I tell you what to fix first.
