The full story
Gamma grew steadily to 60K users over about 2.5 years. Then we added AI, and over the following 2.5 years grew to 70M users. Now at $100M ARR.
The AI Inflection
Pre-AI, we were a good tool. Post-AI, we became viral. AI integration 100x'd our growth.
Profitable from Start
We've been profitable for 2+ years. No need for VC cash burn. Sustainable growth.
Relaunching Works
We announced the AI relaunch directly on Twitter with a simple "Launching today" post. Major feature launches deserve their own marketing moments.
- Pre-AI users: 60K in 8 months
- Post-AI: +60K in 1 week
- Current ARR: $100M
- Valuation: $2.1B
