Gamma Tech Inc.

Maker of Gamma, an AI tool that generates presentations, documents, and websites from text prompts, automating layout, formatting, and design.

Gamma was founded in late 2020 in San Francisco by Grant Lee (CEO), Jon Noronha (Chief Product Officer), and James Fox (CTO); the product publicly launched in 2022. Gamma uses generative AI to create presentations, documents, one-page websites, and social content from a prompt or outline, automating slide layout and design. The company reported being profitable for over two years while scaling past $100M in ARR and roughly 70 million users, with more than 400 million pieces of content generated as of late 2025. Gamma raised a $7M seed round in October 2021, a $12M Series A led by Accel in 2024, and a $68M Series B led by Andreessen Horowitz in November 2025 that valued the company at $2.1 billion, achieved with a lean team of well under 100 employees.
