At Online School № 1, I own the Core Product revenue retention strategy, from analytics through churn experiments. I identified a churn driver in a two-actor subscription model and statistically validated a projection of 37% YoY revenue churn reduction across 50% of the base.
I built the experimentation pipeline and retention analytics foundation from scratch. A/B tests increased completed-task DAU by 88% among new cohorts and engagement by 10% across cohorts.
Previously, as Product Owner of a business unit at Online School № 1, I sustained 1.5× YoY revenue growth for two consecutive years and grew LTV/CAC 5×. I also founded and launched Spanish Language Online School, reaching break-even within 2.5 months.
