Tristar AI raises $12.4 million for real-time AI quality inspection on factory lines

Tristar AI, which makes AI vision software that spots defects on manufacturing lines as products move through them, has raised $12.4 million in a Series A led by Isogon Ventures, according to a press release. Capgemini's venture fund managed by ISAI, NextView Ventures and TenOneTen were among eight other investors.

Unlike rule-based machine vision, Tristar's models adapt to different products, defect types and changing conditions on the line, and link product quality to machine performance and operator activity. The system works with the cameras, controllers and factory software plants already have. Tristar says it runs on more than 500 production lines in North America and Europe, with customers including large suppliers to Toyota, Honda and Mercedes, and that live deployments detect 95% to 99% of defects and usually pay for themselves in about four months.

The company says it grew more than fourfold in the past year. The money goes into its vision and edge platform, new manufacturing sectors and teams for multi-site rollouts.
