A seasoned engineering leader who previously ran engineering and product at Alegeus Technologies, Singh co-founded CodeRabbit in 2023 alongside CEO Harjot Gill. In under two years, the company grew to $40M ARR, 8,000+ paying customers, 2 million repositories, and a $550 million valuation after raising a $60M Series B in September 2025. Based in San Francisco, Singh focuses on operations and product strategy, driving the mission to make AI-powered code review the industry standard.
