Hi there, I’m Graham, CEO of GrowthBook. Thanks for signing up! Our goal is to help you ship features faster and run trustworthy experiments. Here’s the fastest path to your first win: Install the SDK → Pick your language (JavaScript, Python, React plus 20 more languages and frameworks) Create a feature flag → Click Features, then Add Feature. Start with something simple like new-checkout-flow. Add the flag to your code → The SDK docs show you exactly how See it work → Change the flag’s value in GrowthBook and verify your app responds That’s the core loop. Once you’ve got a flag working, you can layer on targeting rules, percentage rollouts, and full A/B tests. I’d love to see what you build. Join our Slack community to share your progress.
