LaunchDarkly Testimonial
" We have really enjoyed using LaunchDarkly and it has already been a boon for us -- allowing us to complete a major rebrand, slow-roll out features, turn off functionality if we hit bottlenecks, and generally allowed us to move faster with more confidence than we could have otherwise. "
- Josh Chu @ Upserve
   Director of Engineering
