Built by Operators, for Operators

Meet the team behind Keel's purchasing and inventory implementations.

Keel was founded in 2021 by three former executives from Echo—Europe's fastest growing online pharmacy, later acquired by Pharmacy2U—where they served as CEO, CTO, and CPO. At Echo, they built custom software to manage the shipping of 50,000 medicines to 600,000 customers daily, scaling the business to $130 million in annual revenue. That first-hand experience of building operations software in a highly regulated environment—where off-the-shelf tools simply couldn't keep up—is the foundation of everything Keel does today. Headquartered in Altrincham, Cheshire, and backed by leading European investors Earlybird and LocalGlobe following a $6 million seed round in 2024, Keel is on a mission to empower operators everywhere with flexible, powerful tools they truly own.
