Case Study: Bluesky scales to 25 million users with Statsig

Bluesky reaches 25 million users in record time with Statsig

Bluesky, an open social network, faced the challenge of building and scaling its product to compete with established incumbents while maintaining a small team. To build a data-driven culture, they turned to Statsig's platform, initially leveraging its product analytics to measure user engagement and track core metrics.

Using Statsig's product analytics, feature flags, and experimentation tools, Bluesky was able to prioritize growth efforts, run over 30 A/B tests, and control mobile releases confidently despite app store delays. This solution enabled them to quickly respond to market changes and validate product decisions. The results included efficiently scaling to 25 million users and a measurable 30% reduction in development stress, as noted by their CTO. Statsig provided the unified platform necessary for this rapid growth.
