Most companies run experiments in a silo. The growth team knows what's working. The product team doesn't. The founders are guessing. Fyxer solved this with one Slack channel. From day one, Kameron Tanseli created #topic-experiments — a public channel where every experiment result, win, and loss was visible to the entire company. Every test that launched. Every result that came in. Wins and losses both, with context on why. The founders — Rich, Arch, and Matt — didn't need convincing. Once they saw the first wave of winners, they wanted it everywhere. Paid marketing started posting their results. The product team followed. Cursor now automatically generates product release docs that feed directly into the channel. It became the company's central nervous system for understanding what's working. The compounding effect was enormous: when everyone can see what's winning, the whole company develops better intuition about what to test next. Ideas come from everywhere. The best experiments aren't always the ones the growth team thinks of. This isn't just a nice-to-have. It's the organizational infrastructure that made 541 experiments across the company possible in a single year. Visibility drives velocity. Does your team have a single place where everyone can see what's being tested and what's working? 🎙️ Full episode + case study in the first comment 👇 #ExperimentationCulture #GrowthEngineering #ABTesting #ProductLedGrowth #Startups
