The tools offered are comprehensive, customer support gets you what you need, and including additional userTargeting is easy to implement. It's exceptionally reliable at splitting traffic and sending data to our warehouse.

Deploying GrowthBook in AWS works really well and we are very happy with the platform and what it can provide. We also had the requirement to use multiple organisations so we can isolate different teams and projects which also works very well. We were able to run the GrowthBook UI and proxies in ECS and have them communicate well along with DocumentDB as the backend database, and EFS for persistent storage. We are still in the experimentation phase but so far everything we played with has worked well. The team is very helpful and provide good support over Slack. Given the project is open source, we found there was one feature we really needed but was not implemented yet. We were able to contribute to the project and add the feature we wanted which was merged and available in the next release (just a few weeks later).

Very smart solutions. Feels like the people who are coding GB, does know very well AB testing and it's challenges, and they come up with very useful features.
