📝 EPISODE DESCRIPTION

Grant Lee is the co-founder of Gamma, the AI-powered presentation tool that’s one of the hottest and most interesting AI startups in the world right now. They’re valued at over $2 billion, and they hit $100 million ARR in just over two years, with a lean team of just around 30 people. Unlike many fast-growing AI startups, Gamma has been profitable for most of its history, has not raised significant funding, and they built a massive business in a category most investors dismissed. In fact, one investor told Grant his idea was “the dumbest idea he had ever heard.” *We discuss:*

1. How Gamma found product-market fit by rethinking their onboarding
2. Their process for building a “word-of-mouth machine”
3. How they leveraged more than 1,000 micro-influencers instead of big names
4. Why focusing on the “first 30 seconds” transformed their business
5. Their approach to pricing that led to profitability within months
6. How Grant thinks about building a durable “GPT wrapper” business
