The Team Behind Keel

Operators who built and scaled real eCommerce fulfilment at pace.

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. Together, they built custom software that handled 50,000 medicine shipments to 600,000 customers daily and scaled the business to £130m in annual revenue. Having experienced first-hand how inflexible legacy systems hold UK businesses back, they built the platform they wished had existed. Headquartered in Altrincham, Cheshire, and backed by £6m in seed funding from Earlybird and LocalGlobe, Keel is on a mission to empower operators across the UK and beyond with flexible, powerful tools they truly own. Their customers—including Bravely, HIVED, Klira, and Egg—are proof that modern eCommerce operations deserve better than spreadsheets and outdated ERPs.
