Origins

When we were heading Growth at Twitter, we saw the power of copy changes. **When we tweaked a push notification from “Elon tweeted” to “Elon _just_ tweeted”, we gained 800K additional users.** We never underestimated the power of copy since that day. The company funded it as a big investment in the difficult years when Twitter’s growth was tanking. However, each change would take 3-6 months to pick, test, approve, and ship. We also didn’t know how to use those learnings systematically to prioritize the next copy change. We started building internal tools to automate this and gained 20% additional user growth. We stumbled upon similar problems and “vision docs” at Pinterest. We knew we were staring at money on the table. We quit our jobs to build [just words](https://justwords.ai).
