cohort retention analysis

Ilya Volodarsky explains how startups can use analytics to measure an MVP and assess product-market fit. He walks through a funnel of acquisition, retention, and monetization, then shows how to track signups, cohort retention, and revenue with event data and analytics tools. He recommends pairing dashboards and customer communication with rapid experiments, and describes a startup tool stack for analytics, usability, email, and data access. His central advice is to choose tools quickly, learn from customers, and change tools as the company’s needs evolve.
