GageList is a cloud-based calibration management software platform developed to simplify and modernize the way organizations manage gage and tool calibration. It was created by Espresso Moon, a Houston-based custom software development firm known for building lean, scalable solutions for industrial clients. GageList is headquartered in Houston, Texas, and operates globally through its web-based platform and mobile apps.
GageList was founded in 2004 as a response to the limitations of traditional calibration software, which often required expensive seat licenses and complex installations. The founding team at Espresso Moon, including certified quality engineers and strategic designers, developed GageList as the first browser-based gage management platform. Since its launch, GageList has grown steadily, onboarding thousands of users across industries such as aerospace, manufacturing, healthcare, and energy.
The platform’s growth has been driven by its simplicity, affordability, and ability to scale without technical or financial barriers. GageList has become a trusted solution for both Fortune 500 companies and small businesses seeking efficient calibration management.
GageList is a privately held company, and there is no public record of external venture funding or valuation figures. It operates under the umbrella of Espresso Moon, which has funded and supported its development internally. The company’s sustainable growth model and low-cost structure suggest a focus on organic expansion rather than aggressive capital investment.
