URL Redirects

Orchestrate seamless experiments across marketing touchpoints—without engaging your IT team.

Connect to Your Data

GrowthBook is warehouse native—it works with your data where it already lives, allowing you to maintain control and avoid vendor lock-in. We're integrated with all major SQL data sources, plus tools like Mixpanel and Google Analytics.

Build Out Your Metric Library

GrowthBook takes the sting out of migrating hundreds of metrics to your new experimentation platform. With GrowthBook, a couple of lines of SQL is all it takes to write a metric to your exact specifications.

Add Metrics Retroactively

GrowthBook allows you to add metrics to past experiments. Now you can capture new insights without running a new experiment.

Pat McGee
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."
Roger Pedroso
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."
Alexander Harmsen
CEO & Founder, Global Predictions
"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%!"
