About
Gamma is an AI presentation and content platform founded to replace the painful, design-constrained experience of traditional slide software with AI-native document creation. Built on the insight that most people spend more time fighting PowerPoint formatting than crafting compelling narratives, Gamma's AI generates polished, visually structured presentations, documents, and webpages from a prompt or outline — eliminating the blank-canvas problem that makes presentation creation a dreaded task.\n\nGamma's platform produces presentations, one-pagers, and web-friendly documents with consistent design, embedded media support, and real-time collaboration. Unlike traditional slide tools, Gamma outputs are responsive and shareable as links, making them more versatile for modern workflows where content is consumed on multiple devices. Users can generate a complete deck from a topic prompt, remix existing content, or use Gamma as an AI co-writer for business communications and thought leadership.\n\nGamma reached $100M ARR profitably with a lean 50-person team and 70 million users — a capital efficiency ratio that is exceptional even by startup standards. The company raised $68M in a Series B at a $2.1B valuation in November 2025. This combination of massive user scale, revenue profitability, and strong investor backing reflects Gamma's ability to serve both the consumer and professional markets for AI-generated content. Its trajectory positions it as a durable challenger to Google Slides and PowerPoint in an era when AI-native tools are rapidly displacing legacy productivity software.
