Company profile
researched Aug 2026GrowthBook is a warehouse-native software platform combining three product areas: experimentation (A/B testing), feature flag management, and product analytics. Experimentation is positioned for data science and product teams running large numbers of rigorous tests, with a configurable statistical model and metrics defined in SQL directly against the customer's data warehouse. Feature flag management includes ramp schedules, guardrails, and automatic rollbacks, plus real-time debugging tools and automatic flag creation for new features. The product analytics component connects to product data for behavioral analysis and trend tracking, and includes an AI data analyst for natural-language questions.
The platform is delivered in two forms: GrowthBook Cloud, a hosted service with instant updates and lower maintenance, and Self-Hosted GrowthBook, which the company states offers the same features running entirely on the customer's own cloud or on premises. Integration is via lightweight SDKs — more than 24 are offered, spanning JavaScript, React, Vue, Node.js, Next.js/Vercel, Python, PHP, Ruby, Java, Kotlin (Android and JVM), Swift/iOS, Flutter, React Native, Roku, C#/.NET, Go, Rust, Elixir, edge runtimes such as Cloudflare Workers, Fastly Compute and Lambda@Edge, and OpenFeature-compatible packages. The company also exposes an MCP server and REST API intended for use by AI agents.
Business model
Software platform sold in a hosted cloud edition and a self-hosted edition, with published plans and pricing tiers and a free entry point ("Start for Free"); the codebase is described by the company as open source.
Traction
The company states it is used by more than 3,000 companies worldwide and that the platform serves over 1 trillion feature flag lookups per day. Published customer results include Dropbox at 3 billion feature evaluations daily, Breeze Airways citing over $1 million in incremental monthly revenue, TodayTix reporting up to a 24% page view lift, Khan Academy reporting a 6.1% correctness improvement in AI tutoring, Oda running over 400 experiments, Lingokids citing 3.5 million+ customers benefiting from tests, Fyxer growing from $1M to $35M ARR with paid conversion moving from 5% to 35%, Toom reporting a 95% uplift in loyalty card signups, and Floward reporting double-digit year-over-year revenue growth.
Latest developments
GrowthBook 5.0 was released, adding agent-oriented workflow capabilities, analytics running on the customer's warehouse, and broader team access to experimentation. Recent company publications include an analysis of why summing experiment wins overstates impact and an episode of The Edge Podcast on false negatives in product testing.
▸Full profile — market position, technology, go-to-market
Market position
Competes in experimentation and feature-flagging tooling, marketing itself against incumbent solutions on cost and on warehouse-native, open-source, self-hostable deployment, with adoption claimed across 3,000+ companies including large consumer and education brands.
Positions on warehouse-native data handling (metrics defined in SQL on the customer's warehouse rather than data held by the vendor), an open-source and self-hostable codebase for full infrastructure control, breadth of SDK coverage across server, client, mobile and edge, a flexible statistical model, and cost positioning described as comparable capability at roughly half the cost of alternatives.
Technology
Warehouse-native architecture in which experiment metrics are defined in SQL and computed against the customer's own data warehouse, paired with low-latency feature flag delivery and lightweight SDKs said to make zero network calls and be 50% smaller. Includes a statistical engine for experiment analysis, auto-rollbacks and ramp schedules for releases, an AI data analyst, and an MCP server plus REST API for agent integration.
Go-to-market
Self-serve free tier and downloadable self-hosted distribution alongside sales-assisted motions including booked demos and recurring live group demos led by a technical expert; developer-facing documentation, SDKs and open-source availability support bottom-up adoption, supplemented by published customer stories and a podcast.
Product teams, engineers, data teams, and product managers at companies running feature releases and experiments; named users include Dropbox, Breeze Airways, TodayTix, Khan Academy, Oda, Lingokids, Fyxer, Toom, and Floward.
