Investment Thesis
Statsig provides tools that help product teams test new features, measure their impact, and decide what to roll out, building on the practice of A/B testing and feature experimentation. Founded in February 2021 by Vijaye Raji, a former Facebook engineering leader, the company brings Meta-style product development infrastructure to every team.
With $40 million in annual recurring revenue and over 140 employees, Statsig serves companies building products in the AI era. The platform provides feature flags, experiments, analytics, and session replay in a unified tool. Statsig was acquired by OpenAI in September 2025, underscoring the importance of experimentation infrastructure for AI-native product development.
Product teams ship features blindly because existing A/B testing and analytics tools are either too expensive, too slow, or too complex for most engineering teams to use consistently, leading to decisions based on gut feel rather than data.
Statsig provides a unified platform for feature flags, A/B testing, and product analytics at a price point and ease-of-use that makes experimentation accessible to every product team — not just Big Tech companies with dedicated data science orgs.
Used by Notion, Figma, Atlassian, Microsoft, and OpenAI for feature rollouts and experimentation; processing billions of events daily with a warehouse-native architecture that keeps data costs manageable.
Product-led growth demands data-driven iteration, but legacy tools (Optimizely, LaunchDarkly) are expensive and siloed; Statsig's all-in-one approach at modern pricing is winning the consolidation play.
