Statsig

Overview

Statsig is a modern product development platform that combines experimentation, feature management, product analytics, session replays, and web analytics into a single tool. Teams use it to test how each release — from features to AI-powered experiences — lands with customers, so they can protect trust and optimize at the speed of AI.

Trusted by thousands of companies from OpenAI to Series A startups, Statsig gives engineering, data science, and product management teams a unified workspace. It replaces expensive point solutions with one integrated platform backed by infrastructure processing over 1 trillion events per day with 99.99% uptime.

Key Benefits

• Brex data teams achieved a 50% reduction in time spent by data scientists and 20% cost savings from consolidating analytics and experimentation tools
• Ancestry increased experimentation velocity 9x from 70 to 600+ annual experiments and reached 3.5 million customers benefiting from personalization
• Notion grew from single-digit to hundreds of experiments per quarter, reaching a 30x improvement in experimentation velocity
• Lime decreased refunds by 20% and canceled trips by 5% using Statsig to measure the impact of every change
• Industry-leading 99.99% infrastructure uptime for API and Console with less than 1ms post-init evaluation latency

How It Works

You install one of Statsig's 30+ open-source SDKs in your app (supporting React, Node.js, Python, Swift, Android, Unity, and more) in just a few steps. You then create feature flags and experiments through the console, target specific user segments, and monitor results in real-time using dashboards, funnels, retention charts, and session replays that are linked to every flag and experiment.

Use Cases

• Data scientists at mid-market companies run Bayesian and frequentist experiments, holdouts, multi-arm bandit tests, and switchback tests without switching tools
• DevOps engineers manage percentage-based and automated scheduled rollouts with environment-based targeting and change review workflows
• Product managers analyze user journeys, conversion drivers, and behavioral cohorts to understand feature impact on core metrics
• Gaming companies run large-scale A/B tests on new game mechanics with near-zero latency SDK evaluation
• B2B SaaS teams consolidate product data, experimentation, and analytics into one platform to reduce tooling costs by up to 20%
• E-commerce businesses measure the impact of every change on refunds and cancellations through linked session replays and metric drilldowns
