Principal Engineer, GoodDog
"GrowthBook checked all my boxes. The fact that it just queries our data warehouse means we can set up much more sophisticated metrics that are based on tables our data team has built with DBT instead of being tied to just querying raw event data."

Head of Software Engineering, Newfold
"Our LATAM team is really enjoying GrowthBook. We migrated all the feature toggles from Optimizely and everything is working fine."

"We've been using the product over the last month to run a few dozen tests and have already increased our overall funnel conversion by about 54%!"
