About me

A product owner who owns the whole problem.

Hi, I'm Esteban. I decide what to build, then test whether it worked.

I start with research to understand what people actually need, then design, ship and test the solution together with engineering and data. Onboarding, pricing, design or a new feature: every idea becomes an experiment we can measure, so decisions rest on evidence, not hunches.

I care about the business as much as the people who use the product, and my job is finding the solution that works for both, with more engagement and better retention to show for it.

    20+ consumer subscription apps. 100+ A/B tests on onboarding, paywalls, offers, pricing and push notifications, with winning ideas rolled out and re-tested across the portfolio, new subscription plans that more than doubled revenue per user in an A/B test, and retention and LTV built into how every test is judged. Event tracking, UX audits and PRDs, side by side with design, ASO, user acquisition and engineering. See the paywall experiments
