Product-led growth thrives on data and experimentation, but most case studies focus on tech giants like Meta or Spotify, where scale enables rapid, statistically significant testing. Startups, by contrast, often lack that luxury. At Soundstripe, they've pioneered a data-informed, hypothesis-driven PLG approach that delivers real impact without massive user volume. In this talk, our speaker will share practical frameworks, key learnings, and unexpected advantages of building a high-velocity experimentation culture in a startup environment - and how larger organisations can adopt these agile, scrappy methods to fuel growth.
