In their words

• "Dumbest idea I've heard" to $100M ARR: Inside the rise of Gamma Grant Lee co-founded Gamma, an AI presentation tool that reached $100M ARR in just over two years with a team of around 30. It is valued at over $2 billion, has been profitable for most of its history, and has not raised significant funding. Lee points to onboarding, word of mouth and micro-influencers as the drivers.
