What Statsig does
Statsig is a product development platform that combines A/B testing, feature flagging, product analytics, session replay, web analytics, and infrastructure analytics in a unified stack for product and engineering teams. Founded in 2021 by Vijaye Raji, a former Meta engineering executive, and headquartered in Bellevue, Washington, the company distributes more than 30 open-source SDKs and serves customers across B2B SaaS, e-commerce, gaming, and AI-adjacent verticals. Its platform processes over 1 trillion events per day and tracks 2.5 billion monthly experiment subjects, supporting large enterprise customers including OpenAI, Microsoft, Atlassian, and Brex alongside a long tail of SMB and mid-market accounts.
The business model is usage-based with no per-seat fees and a generous free tier that funnels roughly 90% of new users into a free path, enabling land-and-expand growth into paid tiers as event volumes and feature-flag usage scale. Go-to-market combines self-serve developer adoption, an open-source SDK distribution strategy, a formal Partner Program launched in December 2025, and strategic alliances such as the Microsoft Azure AI Foundry launch partnership from November 2024. The product roadmap has layered AI-driven capabilities onto the core experimentation engine, including the Statsig MCP Server for AI-agent workflows, an AI Knowledge Graph, AI Experiment Summary, Contextual AI Descriptions, Statbot, and an AI Onboarding Wizard.
In May 2025, Statsig closed a $100M Series C at a $1.1B valuation, reaching unicorn status. In September 2025, OpenAI acquired the company for approximately $1.1B. Subsequently, in May 2026, Amplitude assumed the Statsig brand and approximately 320 customer accounts, with its CFO guiding to $5-7M in revenue contribution from those accounts in the near term.

Revenue model
- Subscription (Pro & Enterprise tiers): Pro tier is a recurring subscription at $150/month baseline; Enterprise tier is a recurring custom-priced subscription with event-based or experiment-based contracts, large volume discounts, and optional warehouse-native deployment.
- Usage-based metered events: Customers are billed for 'metered events' — exposures, log events, ingested metrics, and custom metrics — beyond the included monthly allotment. Overages on Pro tier are $0.05 per 1K events, included on the next month's bill.
- Freemium Developer tier: Free Developer tier with 2M events/month, unlimited flag/config checks, and 50,000 session replays/month. ~90% of customers reportedly start on this free tier (no credit card required), creating the top of a land-and-expand funnel.
- Enterprise contract-based deals: Custom multi-year contracts at enterprise scale, including event or experiment based pricing, warehouse-native deployment, SSO, RBAC, HIPAA eligibility (BAA required), priority support, and outgoing data integrations.
Pricing tiers
| Model | Billing | Price |
|---|---|---|
| Freemium | Monthly | Developer — Free tier for individual builders (2M events/month, 50K session replays, unlimited flag/config checks) |
| Hybrid | Monthly | Pro — $150/month for growing teams (5M events included, then $0.05 per 1K events overage) |
| Other | Multi-year contract | Enterprise — Custom pricing for large organizations with volume discounts and warehouse-native deployment |

Statsig product offering
Product offeringCore offering
Statsig provides a unified product development platform combining A/B experimentation, feature flagging, product analytics, session replay, web analytics, and infrastructure analytics in a single console. Customers integrate the platform via open-source SDKs or connect their data warehouse to run experiments, roll out features behind gates, and analyze user behavior across web and server environments.
Product overview
Statsig offers a unified modern product development platform delivered as a suite of tightly integrated modules rather than a single product. At the core of the offering is the Statsig platform combining Experimentation, Feature Flags, Product Analytics, Session Replay, Web Analytics, and Infra Analytics in one console — with shared data, metrics, and events flowing between modules so teams can move from understanding users (Analytics) to launching safely (Feature Flags) to measuring impact (Experimentation). Surrounding the core are complementary modules including the no-code Marketing Experiments Visual Editor (Sidecar) for marketing-site tests, Warehouse Native for running the entire platform inside the customer's data warehouse (Snowflake, BigQuery, Databricks, Redshift, Athena, Fabric), 30+ open-source SDKs, the Statsig MCP Server for AI-agent workflows, Statsig Lite (free experiment calculator), the Sample Size Calculator, and the Statsig Partner Program ecosystem. Acquired by OpenAI in September 2025 and now managed by Amplitude under a partnership, the platform is positioned as an end-to-end solution for product, engineering, and data teams to ship, measure, and learn.
