Duolingo’s approach to experimentation: The Green Machine
A nice quote in Duolingo’s latest shareholder letter on the results from 2024:

2024 was an extraordinary year for Duolingo. People often ask me, “What’s the secret behind Duolingo’s success?” The truth is, there’s no secret—just our mission and a process. We call the process "The Green Machine." It’s our approach to experimentation, and it’s the engine behind everything we do, from product development to viral marketing. To see how we operate in more detail, I welcome you all to read the Duolingo Handbook, which we just published a few weeks ago. — Luis von Ahn (CEO and Co-Founder Duolingo)

💬 My Experimentation Career Journey

Today’s interview is with Margaret-Ann Seger, Head of Product at Statsig.

Do the thing! This is generic advice beyond just the experimentation industry, but in general I’m always impressed with candidates who find a scrappy way to get experience in the domain they’re applying to. Doing is always > talking.
