Who This Helps
You're a founder operator who needs to make faster decisions with compact evidence. You're tired of debating which experiment to run next. The Data Reliability Leadership course is built for you.
Mini Case
Mei runs a 12-person startup. She spent 7 days last month arguing about whether to test a new onboarding flow or a pricing change. Her team had no shared definition of "active user." After defining a data contract for that metric, she ran one experiment in 3 days and saw a 12% lift in activation. No more guesswork.
Do This Now (5 Steps)
- Pick one metric your team debates most. Write down exactly how you define it.
- Share that definition with your co-founder or lead engineer. Ask if they agree.
- If they don't, write a one-page data contract. Include the metric name, source, and calculation.
- Use that contract to filter your experiment backlog. Only run tests that affect this metric.
- Run your next experiment. Measure the impact in 48 hours.
Avoid These Traps
- Don't define metrics in a meeting without writing them down. Definitions drift fast.
- Don't run an experiment without a data contract. You'll waste time debating results.
- Don't try to fix all metrics at once. Start with one.
- Don't skip the stakeholder narrative. If your team doesn't trust the number, the experiment doesn't matter.
- Don't wait for perfect data. A 90% reliable metric beats a perfect guess.
- Don't forget to celebrate small wins. A 12% lift is real progress.
- Don't run experiments on gut feel. Use the contract to prioritize.
- Don't ignore incidents. If your data breaks, fix it before the next experiment.
Your Win by Friday
By Friday, you'll have one data contract written, one experiment prioritized, and one clear result. You'll stop debating and start moving. That's the point of Data Reliability Leadership.
