The Team Behind Keel

Operators who built at scale—now building the platform they wished existed.

Keel was founded in 2021 by three former executives from Echo, Europe's fastest-growing online pharmacy, later acquired by Pharmacy2U. As CEO, CTO, and CPO, they built custom software to run operations shipping 50,000 medicines to 600,000 customers daily, scaling the business to $130 million in annual revenue. They experienced first-hand how legacy and off-the-shelf software couldn't keep pace—so they built Keel, the platform they wished had existed. Headquartered in Altrincham, Cheshire, Keel raised $6 million in seed funding in 2024 from leading European investors Earlybird and LocalGlobe. Today, Keel empowers fast-moving operations teams everywhere with flexible, powerful software tools they truly own.
