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.
Developer-loved issue tracker with keyboard-first interface and local-sync speed; $52M Sequoia-backed competing with Jira for engineering teams that prioritize developer experience over feature breadth.
About
Linear is a San Francisco-based project management and issue tracking platform built for software development teams — providing sprint planning, issue tracking, roadmaps, bug tracking, and project management with a keyboard-first interface engineered for speed and simplicity. Founded in 2019 by Jori Lallo, Tuomas Artman, and Karri Saarinen (former Coinbase and Airbnb engineers) and backed by Sequoia Capital, Accel Partners, and other investors with $52 million raised, Linear has become the preferred issue tracker for growth-stage technology companies who consider Jira bloated and slow.
