成立一年的初创公司Trajectory融资4500万美元，估值达3亿美元，目标是让非技术专家也能训练AI模型。
Trajectory, founded in 2023, closed a $45M round valuing the company at $300M. Its platform enables domain experts — not ML engineers — to train and fine-tune models using intuitive interfaces and proprietary data, with early traction among mid-market enterprises. This signals strong investor appetite for infrastructure that shifts AI development leftward into business teams. For early-stage AI app founders, this is a clear signal: avoid over-investing in foundational model R&D. Instead, prioritize integration with accessible training layers — especially those supporting private deployment, auditability, and rapid iteration on domain-specific feedback. Speed-to-value now hinges less on model size and more on how quickly a sales manager can adjust prompts, label edge cases, and ship an updated workflow — all within existing IT governance. Building atop such platforms cuts time-to-MVP from months to days, while dramatically lowering hiring and compute overhead.
