Testimonials

“GrowthBook gave us a modern experimentation and release platform that actually fits how Dropbox works. We can run analytics directly on our data lake, roll features out safely in stages, and support teams across different stacks without duplicating data or tooling.”

Alex Kalish
Engineering Manager, Dropbox

“Being able to turn a feature on and off with a flip of a switch 
is fantastic... That’s so much easier than having to do a deploy or a roll-back.”

John Resig
Chief Software Architect, Khan Academy

“People only see the wins, but there’s actually greater value in avoiding losses. We’ve stopped changes that could have cost millions.”

Merritt Aho
Digital Analytics Lead at Breeze Airways

“GrowthBook has changed the way we think about experiments... It allowed us to uplevel our code, speed up decision-making, and focus on what we do best.”

Diego Accame
Director of Engineering, Upstart

“Experimentation showed what customers actually do rather than what we assume they’ll do.”

Marek Maciusowicz
Head of Engineering, Treatwell

“We don’t need any code changes, we don’t need an app release. We just configure the new tests and launch right away.”

Filipa Batista
Product Manager, Lingokids

"We are always experimenting now. It’s a natural part of product development. This is due to GrowthBook and the ease of usage both in the UX and in the seamless integration with Snowflake/DWH."

Fredrik Jørgensen
Head of Insight, Retail Platform, Oda

"GrowthBook's results speak for themselves. Every time we do a test, we see benefits for our audiences and our partners. These posters are our one shot, and we wouldn't want to fly blind."

Senior Director
Head of Insight, TodayTix

“GrowthBook lets us build experiments exactly how we want. The ability to target based on culture and geography, as granular as needed, is a major win for us.”
