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.
