Why Traditional A/B Testing Falls Short

Too Slow

Weeks to months for results. By then, the opportunity's gone.

Too Expensive

$20k-50k all-in organizational cost per failed test. Engineering time, PM time, analytics, QA, opportunity cost—when 70% fail, that's expensive waste.

Too 'Dumb'

Only measures average uplift. Can't tell you why it failed or how to fix it.

FacetLab simulates outcomes before launch

Test your experiments with virtual customers powered by reinforcement learning. Get accurate predictions in hours, not weeks—before spending a dollar on real traffic.
