GrayMatter: AI-Based Robotics Company Raises $45 Million In Series B Funding

By Amit Chowdhry • Jun 24, 2024

GrayMatter Robotics, an AI-based robotics leader empowering humans with intelligent automation, announced $45 million in Series B funding. Wellington Management led the funding round, which also included NGP Capital, Euclidean Capital, Advance Venture Partners, SQN Venture Partners, and other existing investors 3M Ventures, B Capital, Bow Capital, Calibrate Ventures, OCA Ventures, and Swift Ventures.

The U.S. manufacturing industry is dealing with a growing backlog of unfilled orders due to a severe labor shortage. And many of these roles are hazardous and demand extensive training, leading to a critical gap of 3.8 million unfilled jobs. With about half of these manufacturers’ orders on hold waiting to be fulfilled, GrayMatter’s solutions are essential in addressing these challenges.

GrayMatter’s smart robotic cells are future-proofing high-variability manufacturers’ businesses by increasing productivity while enhancing quality consistency and reducing costs. They autonomously handle complex tasks like sanding, polishing, grinding, coating, and finishing – which are traditionally labor-intensive and ergonomically challenging jobs—enabling businesses to meet global demand while significantly improving the quality of life for shop-floor workers.

Founded in 2020 by SK Gupta, Ariyan Kabir, and Brual Shah, GrayMatter plans to use the new funding to actively hire a wide range of roles to meet customer demands, expand its Los Angeles headquarters, and accelerate the development and deployment of its next-generation AI-powered robotic solutions.

GrayMatter’s advancements continue to set new industry standards. For example, its proprietary GMR-AI technology enables robots to self-program and adapt to high-mix manufacturing environments, offering consistent quality and reducing cycle times.

In the past two years, GrayMatter Robotics deployed robots across North America in aerospace, defense, specialty vehicles, marine, recreation, and general manufacturing industries, processed over 7.5 million square feet of product surface area, and holds ten patents.

GrayMatter Robotics’ solutions work two to four times faster than manual operation, and training that usually takes six months for humans now only takes less than a day. And the robot helps businesses address sustainability goals, resulting in a 30% or more reduction in consumable waste and reduced energy consumption than traditional methods. Manufacturers have nearly uninterrupted operations with a system availability of 95% to 98%, and most of the contingencies can be resolved in under five minutes. The representative products includes Scan&Sand, Scan&Polish, Scan&Buff, and Scan&Grind.

GrayMatter Robotics’ solutions are used by a diverse range of industries, including aerospace & defense, specialty vehicles, maritime, metal fabrication, and consumer products. By offering turnkey solutions in a Robot-as-a-Service (RaaS) format, GrayMatter Robotics helps manufacturers improve productivity, enhance production capacity, and reduce costs associated with scrap, repair, and rework.
