Having strong user intuition, good design is table stakes for successful products.

At @duolingo, here’s how we make this process repeatable and scalable: 🧵 Image Each quarter, we run over 500 A/B tests.

Every single one of them follows this process:

1. Form a hypothesis

2. Quickly iterate on the best ideas

3. Get the key learnings and next steps

4. Rinse and repeat Image

Macbook Air + Code Server + Coder on VPS or

Macbook + @github Codespaces + Copilot
