AI Startup Trajectory Closes $45 Million Series A Funding Round

AI startup Trajectory has raised a $45 million Series A at a $300 million valuation, TechCrunch reported on November 3. Sequoia Capital led the round, with participation from Nvidia, Bessemer Venture Partners, and Bain Capital Ventures. Trajectory's platform collects feedback on how AI models perform in real-world applications and uses it to retrain open-source models for specialized tasks. Customers including legal AI firm Harvey and financial AI firm Rogo have already used the platform for post-training, and Trajectory is now opening it to the public. The raise signals continued investor appetite for AI infrastructure focused on model fine-tuning and evaluation. Watch for adoption metrics among enterprise clients and whether the public launch expands Trajectory's customer base beyond its initial users.
