GelSight

GelSight is a tactile sensing and optical metrology company that develops high-resolution sensors for 3D surface analysis and robotic touch applications. The company's technology uses a proprietary elastomeric gel that enables capturing surface geometry of any material at the micron level, combined with AI and software frameworks that produce 3D images suitable for quantitative analysis. Unlike scanning electron microscopy, GelSight's technology works with any surface without requiring specialized sample preparation. The product portfolio includes GelSight Modulus and Modulus HR for bench-top metrology, GelSight Mobile and GelSight Mobile Shock Protected for handheld field inspection, GelSight Max for high-precision applications, and GelSight Mini, a tactile sensor for robotics applications. Metrology applications include hole diameter measurement, scratch and defect measurement, fastener flushness inspection, XYZ dimensional measurements, weld inspection, pit detection and corrosion analysis, surface roughness measurement, radius of curvature measurement, replica measurement with image transformation, shot peen analysis, and AI-based perceptual quality assessment. Robotics applications include realtime 3D sensing and pose estimation for robotic manipulation. GelSight serves industries including aerospace and defense, automotive, robotics, energy, forensics, additive manufacturing, research and academia, and chemical, providing both mobile metrology and tactile robotics solutions that bring human-like touch sensitivity to machines for surface texture detection, geometry measurement, and contact response. Founded in 2011 and headquartered in Waltham, Massachusetts, GelSight has raised $16.2M in Series B funding from investors including Anzu Partners, America's Seed Fund, Omega Funds, and Scout Ventures.
