Trajectory, a San Francisco-based research and product lab focused on continual learning in AI, has been linked in an unverified report to new Sequoia Capital funding at a $300 million valuation, but no public confirmation supports that claim. The company's only confirmed financing is a $15 million seed round announced in June 2026 and led by Conviction, with participation from Bessemer Venture Partners, Radical VC, BoxGroup and angel investors including Jeff Dean and Fei-Fei Li. Trajectory is building technology designed to let AI models learn incrementally from new information instead of relying on full retraining cycles, an approach aimed at reducing the high cost of repeatedly retraining large models. A central challenge for continual learning is catastrophic forgetting, where systems lose previously learned information as they absorb new data. No confirmed details are publicly available on Trajectory's current valuation, Sequoia's involvement or the company's operational traction beyond the seed announcement.
