Experimentation That Proves Real Incremental Lift
Test fewer, clearer hypotheses with disciplined holdouts and meaningful horizons. Use ghost holds for channels with spillover, and track guardrails—complaints, unsubscribes, and support load. Avoid pre/post traps by using randomized designs where feasible. A team discovered win-backs worked only after resolving a product bug, not before. Share your experimentation cadence and sample sizes, and we’ll help design tests that estimate long-term retention effects, not just instant clicks, so you can invest confidently and scale winners responsibly.
