CQUELLE

Here's the GoodFirms "About your company" text:

CQUELLE is a boutique software development company based in Hamburg, Germany, founded by a developer with 20 years of engineering experience. We build dedicated development teams and custom software applications for mid-sized companies in regulated industries.

Our focus areas are EdTech, HealthTech, FinTech, and veterinary software — domains where compliance, data security, and deep technical understanding are non-negotiable. We work with clients across DACH, Europe, and the US who need a reliable European development partner, not a vendor rotating anonymous engineers through their codebase.

The core stack is .NET and React, supported by Docker, Azure, and modern CI/CD infrastructure. We integrate AI-assisted development tooling into our workflow under a formal internal usage policy — meaning faster delivery with clear boundaries around how client data is handled.

What sets CQUELLE apart is how we work. Every engagement starts with a technical founder who understands the problem before writing a line of code. We keep teams small and stable. Communication is direct — no layers of project managers between you and the people building your product.

Our portfolio includes community management platforms, industrial quality control systems, trucking logistics software, veterinary practice management, educational assessment platforms, and programmatic advertising technology.

For companies where getting it right the first time matters.
