Trajectory Completes $15M Series A at $115M Valuation, Led by Former DeepMind Researchers

According to Beating, Trajectory, a continual learning platform founded by former researchers from Google DeepMind, Apple, OpenAI and Meta, completed a $15 million Series A funding round at a $115 million post-money valuation. The round was led by Conviction, with participation from Bessemer Venture Partners, Radical VC and BoxGroup. Google Chief Scientist Jeff Dean and Stanford Professor Fei-Fei Li participated as individual investors.

The platform addresses a key gap in AI development by converting user corrections, retries and feedback into training signals for real-time model updates. Trajectory integrates with observability platforms like LangSmith to capture agent execution traces and user telemetry data, automatically converting these into standardized formats for fine-tuning and evaluation. The company has partnered with AI-native agent platforms including Decagon, Clay and Harvey.
