The Team Behind Keel

Operators who built for 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 at Echo, the founders built and operated custom software that shipped 50,000 medicines to 600,000 customers daily, scaling the business to $130 million in annual revenue. They experienced first-hand how off-the-shelf tools buckle under real operational complexity, particularly in highly regulated environments where precision and auditability aren't optional. That experience became Keel's founding principle: operators everywhere deserve flexible, powerful software they truly own. In 2024, Keel raised $6 million in seed funding from leading European investors Earlybird and LocalGlobe, and continues to build the modern ERP alternative for fast-moving teams.
