CQUELLE

Updated in August, 2026

CQUELLE GmbH builds software for companies that need more than a template: healthcare platforms, fintech systems, edtech products, and internal enterprise tools. The company sits in Hamburg (Amtsgericht Hamburg, HRB 159619, founded October 2019), and its engineers work from Poland, Romania, and Ukraine, which keeps delivery inside European time zones and European data protection law at 60 to 70 percent below Western European in-house cost. Most engagements take one of three shapes: building a product from scratch, placing a dedicated team that works under the client's management, or modernizing a system that has outgrown its architecture. The stack behind most of that work is .NET on the server and React in the browser, with PostgreSQL or SQL Server underneath, on Azure or AWS. A few things clients notice. Dedicated teams are typically assembled in 2 to 4 weeks. The founder reviews architecture and still commits code. AI tools are used as accelerators, and code goes through engineer review before it ships. CQUELLE also builds its own products. Timeplanned, an app for independent teachers that handles lesson scheduling and month-end payment tracking, runs in production and is operated entirely in-house.
