Grant Lee: Building Gamma’s AI Presentation Company to 100 Million Users
•November 11, 2025

Summary
Grant Lee co‑founded Gamma in 2020 to reinvent presentations by making visual storytelling effortless for non‑designers, eventually scaling the AI‑powered platform to roughly 100 million users and approaching $100 million in annual recurring revenue. Early investor pushback—citing the dominance of incumbents like Microsoft and Google—spurred the team to embed growth into product strategy, leveraging AI to create a fundamentally different set of design primitives and interactive, mobile‑responsive decks. By marrying pre‑AI insights about flexible, multimedia‑rich content with later advances in generative models, Gamma introduced features such as collaborative workspaces, AI‑driven editing, and a one‑click interface that rivals traditional slide tools. The company now expands into enterprise use cases and next‑generation capabilities like avatar‑driven sales presentations.
Original Description
Grant Lee was told Gamma was "the worst idea ever heard" by an investor who hung up mid-Zoom—yet he built it to 100 million users and $100M ARR without spending a dollar on advertising.
While competitors hired aggressively, Grant's team of seven refused to grow, dedicating 25% of their tiny team to design and personally onboarding every influencer themselves.
They reveal how ignoring AI for their first two years, then orchestrating multiple models in ways the frontier labs can't replicate, let them steal the presentation market from Microsoft and Google—going from 60,000 signups in eight months to 50,000 per day.
