Ronak Malde is Co-Founder and CEO of Trajectory, a research lab and product company building the platform for continual learning so AI models keep improving from real product usage. He is based in San Francisco.

Ronak earned a master's degree in Computer Science at Stanford with an AI concentration, where he met his future co-founders Michael Elabd and Arjun Karanam. He then helped ship Windsurf and trained its agentic coding model SWE-1 at Codeium, before joining Google DeepMind to work on Antigravity and Gemini 3.

Ronak believes real user interactions reveal the challenges of deployed agents better than curated benchmarks, and he argues the era of frozen software is ending. He was named to the 2025 Exceptional 100 list and left Google DeepMind to build Trajectory.

Trajectory exited stealth in May 2026 with a $15M seed round and has since raised a Sequoia-led Series A, bringing total funding to about $60M. Investors include NVIDIA, Bessemer Venture Partners, and Bain Capital Ventures.

Trajectory works with companies including Clay, Decagon, Harvey, Rogo, and Mercor, and launched its self-serve post-training platform on November 2, 2026. Its research includes Continual Grading and the GS1 algorithm, helping fields like law and medicine build custom models.
