Top takeaways from our favorite conversations
Build composite metrics (e.g., CPQI) to align finance, engineering, and data science around shared outcomes.
The biggest thing that gets a team testing is to just do it. Stop designing the perfect experiment and get something simple live to take away the mystery.
Share losses as openly as wins. Wins build credibility, and losses build the psychological safety a testing culture runs on.
When you struggle to land a result, lead with the story of what the customer did, then bring the numbers.
A feature that fails early in a flow can succeed later; placement and timing often matter more than the idea itself.
Win rate matters less than learnings per test — DoorDash ships company-wide experiment summaries (win or lose) that the CEO actively reads and responds to, creating cultural accountability around testing rigor.
Simplification has a limit. Removing too much can strip away the cues and context buyers actually need to decide.
Democratize experimentation with a centralized platform and self-serve tooling; reset baselines regularly.
Close every losing test with two questions: did it work for a granular segment, and is the idea worth further investment?
Documenting experiments in a centralized Wiki creates a growth flywheel: Fanatics' Wiki feeds their roadmap with iterations on already-built features, reducing tech dependency and accelerating velocity.
One centralized team of about 40 people tests every major change to Home Depot's $25B online business, serving 40–50 business teams with consistent hypothesis and analysis standards.
Massey's first test removed navigation from UPS's shipping checkout flow and delivered $35 million in incremental revenue—proving e-commerce best practices apply even when customers think "this is just a tool, not e-commerce."
Scale experimentation with AI: use Cursor desktop/cloud agents for parallel builds and visual QA; orchestrate docs/analysis via Claude; automate cleanups and reporting.
DoorDash's price experiment proved price by itself doesn't predict orders. Different customers want different things at different times, which pushed the team toward personalization.
Shift from MVP to MVT: list leap-of-faith assumptions and design minimum viable tests before you build.
Test metrics before you test features — usage time could signal engagement or just mean your product takes too long to do its job.
Separate your two experimentation modes: high-volume CRO chases many small wins, while big uncertain bets deserve multiple shots to de-risk.
