Whether you're managing products across multiple warehouses, handling lot and expiry tracking, or automating reorder points based on demand, Keel models the system around your exact operations—not the other way around.

Built by founders who shipped 50,000 medicines daily to 600,000 customers—Keel's infrastructure is engineered for serious operational scale.
Operators who built enterprise-grade software from scratch and created Keel so you don't have to.
Keel was founded in 2021 by three former executives—CEO, CTO, and CPO—from Echo, Europe's fastest-growing online pharmacy, later acquired by Pharmacy2U. At Echo, they built the custom software that powered daily shipments of 50,000 medicines to 600,000 customers, scaling the business to $130m annual revenue. They experienced first-hand how legacy tools couldn't keep up and off-the-shelf software created more problems than it solved. Based in Altrincham, Cheshire, Keel was built to give every operator the same competitive advantage those custom tools provided at Echo—without needing a large development team. In 2024, Keel raised $6m in seed funding from Earlybird and LocalGlobe, backing their mission to empower operations teams everywhere with flexible, powerful software they truly own.
Several tools offer Shopify integrations, including TradeGecko, Cin7, and Linnworks—but these are off-the-shelf products with fixed workflows. Keel builds custom inventory management software with a tailored Shopify API integration, meaning your stock levels, orders, and returns sync in real time exactly the way your operations require, with no workarounds or feature gaps.
