Meet the Keel Team

Operators turned builders, on a mission to give every business the software it deserves.

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 that shipped 50,000 medicines to 600,000 customers daily, scaling the business to $130m in annual revenue. That hands-on experience in a highly regulated, fast-moving environment gave them a deep understanding of what operators actually need: flexible tools they truly own and can iterate on quickly. In 2024, Keel raised $6m in seed funding from Earlybird and LocalGlobe to bring this vision to businesses everywhere. Today, Keel powers operations teams at companies including Bravely, HIVED, Klira, and Egg.
