Is 1 year to choose an experimentation tool overkill? Khan Academy says no. Dr. Kelli Hill, Head of Data at Khan Academy, shared how they thought about it. After 2.5 years rebuilding their entire backend and porting a million lines of code from Python to Go, throwing away their data investment on the wrong tool wasn't an option. The consideration: build, buy, or open source. They had a long document analyzing every option. Where they landed was GrowthBook. The reason wasn't feature checkboxes. It was that GrowthBook plugged directly into everything they'd already built. Existing data warehouse. Existing pipelines. Existing metrics. According to Dr. Kelli Hill, Head of Data at Khan Academy, "Everything just worked." And critically, it didn't slow down their site for a million daily active users. Khan Academy was smart about their data long before they had an experimentation platform. GrowthBook was the tool that finally let them use it. #experimentation #abtesting #productmanagement
