These nine stories, by the numbers.
Not projections. Documented results, measured against control groups.
Every case, documented.
What's inside every case study.
The research, not just the result
Every case opens with what we actually found — heatmaps, surveys, session recordings, and the psychological drivers behind each buying decision.
The tests that won — and lost
We publish the losers' ledger alongside the winners. A 52.6% win rate means roughly half of all tests fail, and the failures shape the roadmap.
The revenue math, shown in full
