Tristar AI
Tristar AI puts a pair of eyes on the factory floor that never blink. The Boston-based company builds AI-powered smart cameras and enterprise software that watch production lines in real time, recognize what human workers are doing, and flag defects or skipped steps the instant they happen - before a bad part ships or a machine goes down. Founded in 2022 by a team out of MIT, Harvard, and UT Austin, Tristar serves precision manufacturers in plastics, automotive, and chemicals, promising 95-99% defect-detection accuracy and deployment in about two weeks.
Salem Karani
Salem Karani is the co-founder, CEO and CTO of Tristar AI, a Boston-based startup building an AI-native computer vision platform for real-time quality monitoring and human-machine interaction on factory floors. Raised inside his family's plastic film manufacturing business, he turned a childhood spent around production lines into a company that helps manufacturers cut scrap, reduce waste, and improve uptime. Tristar's models read human motion at a kinematic level, letting them drop into new factories without retraining. The company raised a $3.15M seed in June 2024 led by Las Olas Venture Capital and TenOneTen Ventures.
