Product experimentation
What is Product experimentation?
Product experimentation uses bounded tests and predefined evidence to reduce uncertainty about customer behavior, outcomes or technical feasibility.
Usability observation, controlled comparisons and feasibility rehearsals answer different questions. Match the method to the uncertainty.
Record the hypothesis, guardrails, observation plan and decision before reviewing results. An ambiguous outcome is not proof of effectiveness.

- Synthetic usersSynthetic users are AI-simulated personas used to generate and rank hypotheses about how real customers might react, before real-user testing confirms them.
- AI evaluationsAI evaluations are repeatable tests of a model or agent workflow against defined tasks, acceptance criteria, and observable failure categories.
Field notes covering Product experimentation
- When Building Gets Cheap, Product Judgment Gets ExpensiveClaude Code expands the space of possible products. The differentiator is no longer a convincing specification—it is choosing, testing and shipping the right experience.
- The Best Product Decision Might Be a Smaller BetWhen the evidence is thin, conviction is not a substitute for a learning plan. A practical framework for reversible decisions, meaningful experiments, and stopping rules.
- Synthetic Customers: Test the Funnel Before AI Traffic Finds ItBrowser agents can pressure-test a journey before launch. Here is where synthetic users find real friction — and where plausible simulations become expensive theater.
