More A/B tests, shipped faster.
I'm a CRO and A/B testing consultant. I've run over 100 tests for inne, took Eduki from 5 to 120+ tests a quarter, and spent 11 years at trivago running hundreds more.

What Clients Say
"Before his help, we relied on developer-implemented tests which severely limited our testing velocity. We went from running a handful of tests to a robust testing calendar at both businesses."

Results, not promises
How I Work
How I ship tests faster
Run tests side by side
Several tests at once, not one after another. Why overlapping tests are safe.
Ship on clear signals
When a test can't reach full significance in time, I ship reversible changes on a clear direction and keep watching, so the site improves every month.
Done for you, or with your team
I run the whole program myself, or set up the tools and train your team to launch tests on their own. You choose, per project.
Every audit starts with claude-cro, my open-source CRO audit skill for Claude Code. Run it on your own site for free, or see the audit it made of this site.
