About
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.

Grok 3, released in February 2025, achieved top scores on the AIME math reasoning benchmark and ARC-AGI test, briefly positioning xAI as a frontier model lab.
