Company Overview
About Split.io
Split.io is a San Francisco-based feature management and software experimentation platform — acquired by Harness in May 2024 for an undisclosed amount, having raised $110 million in total pre-acquisition funding from Lightspeed Venture Partners, Accel Partners, and Harmony Partners — providing engineering teams, product managers, and data scientists with feature flag infrastructure, progressive delivery, A/B testing, and feature impact measurement tools that enable software teams to safely release features to targeted user segments, run controlled experiments, and measure feature impact on business metrics. Split reached $75 million in annual recurring revenue as of April 2025 under Harness ownership, serving enterprise software development teams who need controlled feature rollouts and experimentation alongside their CI/CD pipelines.
Business Model & Competitive Advantage
Split's feature management platform enables the 'dark launch' and 'canary release' deployment patterns that modern software teams use to separate code deployment from feature activation: instead of releasing a new feature to all users simultaneously (high risk if bugs exist), engineering teams deploy feature-flagged code to production (inactive by default), then use Split's SDK to activate the feature for 1% of users, monitor error rates and performance metrics, expand to 10%, 50%, and ultimately 100% — or roll back instantly without a code deployment if issues arise. The experimentation layer (statistical significance testing for A/B experiments) connects feature flag activations to business metric outcomes (conversion rates, revenue per user, session length) — enabling product teams to measure whether a new feature actually improves the metrics it was designed to improve, rather than shipping features based on intuition. The targeting rules (activating features for specific customer segments based on plan tier, geography, device type, or user attributes) enable personalized feature experiences without maintaining separate code branches.
Competitive Landscape 2025–2026
In 2025, Split.io (Harness) competes in the feature management, progressive delivery, and software experimentation market with LaunchDarkly (dominant feature management platform, $350M raised at $3B valuation), Statsig (feature flags and experimentation, $100M raised), and Optimizely (web experimentation and feature flags, acquired by Episerver) for enterprise engineering team feature management infrastructure. The Harness acquisition integrates Split's feature management into Harness' broader software delivery platform (CI/CD pipelines, cloud cost management, chaos engineering, security testing) — creating a unified software delivery intelligence platform where feature flags are part of the continuous delivery workflow rather than a standalone tool. LaunchDarkly's dominance in the enterprise feature flag category (the go-to-market category Split pioneered) creates the primary competitive dynamic. The 2025 strategy under Harness focuses on the Harness Feature Management integration with the Harness Pipeline for end-to-end feature delivery tracking, growing the Split experimentation statistical analysis capabilities, and cross-selling to Harness's existing CI/CD customer base.
