## Summary

May 2025: $100M Series C at $1.1B valuation (unicorn status) led by Iconiq Growth; Processing 1 trillion events/day; Customers: OpenAI, Microsoft, Figma, Notion, Bloomberg, Grammarly, EA; 100K+ features released

## Company Overview

Statsig is an experimentation and product observability platform founded in 2020 and headquartered in Bellevue, Washington. The company was founded by ex-Facebook engineers who built and scaled Meta's internal experimentation infrastructure, and launched Statsig to make enterprise-grade A/B testing and feature flagging accessible to companies of all sizes. Its core technical differentiator is a high-throughput event pipeline built to process over one trillion events per day without compromising real-time latency.\n\nThe platform provides feature flags, A/B and multivariate experimentation, product analytics, session replay, and a built-in stats engine that surfaces statistically rigorous results without requiring a dedicated data science team. Statsig serves product, engineering, and growth teams who need to ship features safely, measure impact precisely, and learn from every deployment. Notable customers include OpenAI, Microsoft, Figma, Notion, and Brex — organizations that run experiments at massive scale and require infrastructure-grade reliability.\n\nIn May 2025, Statsig raised a $100 million Series C led by Iconiq Growth at a $1.1 billion valuation, officially reaching unicorn status. This funding round validated Statsig's position as a category leader in experimentation platforms, competing with Optimizely, LaunchDarkly, and Amplitude. The company's ability to land and retain top-tier AI and software companies as design partners demonstrates that its infrastructure-grade reliability and analytics depth are compelling differentiators in an increasingly crowded product analytics market.

## Frequently Asked Questions

Statsig Statsig reaches $45M funding as modern feature flagging and product experimentation platform, following 2021 Vijaye Raji founding

### When was Statsig founded?
Statsig was founded in 2021 in San Francisco, California. Vijaye Raji, Tore Hanssen, and Daniel Loomb (ex-Facebook) founded Statsig in SF in 2021 with modern feature flagging and experimentation from Facebook infrastructure, raised $45M with warehouse-native approach.

### What are Statsig's major milestones?
Statsig's history includes several key milestones: 2021: Statsig Founded SF 2022: Series A $10M Funding 2023: Series B $45M Growth 2024: Modern Experimentation Leader

### What is Statsig's mission?
Statsig's mission is to Bring Facebook-scale experimentation platform to every company.

### Who founded Statsig?
Statsig was founded by Vijaye Raji. Facebook engineers who built experimentation infrastructure powering billions of experiments

### What products or services does Statsig offer?
Statsig Statsig reaches $45M funding as modern feature flagging and product experimentation platform, following 2021 Vijaye Raji founding

### What is Statsig's experimentation infrastructure and why is it distinctive?
Statsig's core technical differentiation is its high-throughput event pipeline — engineered by former Meta engineers who built Meta's internal experimentation system — capable of processing over one trillion events per day without introducing latency into the applications being measured. Most SaaS experimentation platforms struggle with scale: high event volumes create ingestion lag that makes real-time experiment results unreliable and forces companies to sample rather than measure 100% of traffic. Statsig's infrastructure eliminates these bottlenecks, enabling enterprise product teams to run statistically rigorous experiments on full traffic volumes even at the scale of millions of daily active users.

### What customers does Statsig serve and what use cases?
Statsig serves product, engineering, and growth teams at technology companies ranging from high-growth startups to public technology firms — including Notion, Brex, OpenAI, and Figma as publicly disclosed customers. The platform is used for A/B testing product changes (UI experiments, algorithm changes, pricing tests), progressive feature rollouts with real-time monitoring for safety metrics, product analytics to understand user behavior, and session replay to diagnose specific user experience issues. Statsig's broad capability set — combining feature flags, experimentation, analytics, and session replay in one platform — addresses the tool consolidation needs of engineering-led product teams who want to reduce the number of vendors they manage for experimentation workflows.
