Results, not hours.
Custom software by engineers you approve yourself.
CQUELLE is a bespoke software development company in Hamburg, building and modernizing software for HealthTech, FinTech and EdTech. No piece of work is bigger than 24 hours, and every result is shown at the next weekly demo.
Know where your project stands. Every week.
Most of our clients came to us after a project where the invoices kept arriving and the software did not. So every piece of work here is a story: one thing your users will be able to do, with what done means written down and approved by you before anyone starts. On demo day you see it working, and you accept it or send it back.
No story is bigger than 24 hours of work, so nothing hides for a month. Hours stay our internal arithmetic. What you see running is the result.
Bespoke software we delivered, from a donor platform to a flashcard app
Three worries we hear in almost every first call
Each answer is something you can check, in the contract or in the repository.
“I cannot judge the code myself.”
You do not have to. You approve every engineer in your own interview, and every piece of work is described in plain language before it starts. Nothing merges without code review and a green pipeline. The handbook we work by is public on GitHub, so you can hold us to it.
“The last agency went quiet after month two.”
You get access to the repositories and the board in week one, and a demo every week after that. Fixed-scope deliveries carry a 30-day warranty. When a date is at risk, you hear it before the estimate runs out, which is a rule in the handbook, not a courtesy.
“I do not want to build an IT department.”
A standing team of 2–10 engineers you interview, or a fixed scope with one price for a list you approved. Add people within 1–2 weeks, scale down with 30 days' notice. We also take over systems a previous vendor left behind, after a 5-day look at the code.
Boutique custom software development from Hamburg, for businesses where the rules are part of the product.
Four fields where audit trails and data residency matter as much as the screens. If yours is not here, ask.
HealthTech
Patient and practice software, from a veterinary platform rebuilt live to a blood-donation operator. GDPR by default, HIPAA where your market requires it.
FinTech and banking
Advisory and banking platforms where every decision has to be attributable, so the audit trail shapes the architecture before the first screen.
EdTech
Assessment and learning platforms, including an eAssessment system used in research studies in 60+ countries, with tens of thousands of test-takers per cycle.
Insurtech and public sector
Policy, claims and underwriting workflows where the complexity lives in the rules; public-sector requirements, where EU team locations and on-premise come first.
From the first call to the first code in your repository, in four weeks
The price appears in the second step, for a team and for a fixed scope alike.
| Week | What you get |
|---|---|
| Week 1 | A 30-minute call, then discovery Bring what you have, even a one-page idea. A discovery session on your product and architecture follows in the same week. |
| Weeks 2–3 | The proposal For a team: roles, seniority, the CVs and your interviews. For a fixed scope: the list of stories, each with written acceptance criteria, and one price for exactly that list. |
| Week 4 | First code ships The team works in your repositories and your tools (Jira, Azure DevOps or Linear), with a pipeline in place before the first story is done. From here on: a demo every week, and you accept each story within 5 business days. |
| After launch | Hosting, operate plan, or a handover Hosting in Frankfurt or in your own cloud, an operate plan if you want one, and a handover written for your own engineers if you do not. The code and the accounts are yours in both cases. |
What clients say
Rated 5.0 on Clutch across five reviews.
It's been a pleasure working with CQUELLE team. In an era where AI tools can do everything, it's hard to find people that can understand the business need and ask the right questions. A great profile for a startup where things are not perfectly square and a lot must be achieved.
They were very responsive and reactive both in the planning and execution of the project.
They demonstrated a remarkable ability to deliver items on time consistently.
Boutique on purpose
CQUELLE GmbH was founded in 2019 and has stayed small by choice. The engineers are mid to senior and work in pods of 2–5 with a named lead.

A larger team is assembled per engagement from the same pool, and you approve each member. How that works
When we are not the right fit
- You need a fifty-person program.
- We are boutique by choice: pods of 2–5 engineers, a few of them in parallel. A system integrator is the better call there.
- Your stack is not ours.
- We work in .NET, Python, React and Next.js, and we maintain Angular. For a PHP, Java or Ruby codebase there are better teams, and we will name a few.
- You need the team in your office every day.
- The contract is under German law and your contact is here in Germany; the engineers work from Poland, Estonia, Romania and Ukraine, in your hours and your tools. On-site meetings when they are needed.
- You want an open-ended bill by the hour and nothing written down.
- We can staff a team per role and month, but the work on the board is still stories with written acceptance criteria, so there is always something to hold us to.
The things people ask before they ask for a proposal
What does CQUELLE do?
Dedicated team or fixed scope: which one do I need?
Do I own the source code and the infrastructure?
How does CQUELLE use AI, and can we opt out?
What does it cost?
Where is CQUELLE based, and in which time zones do you work?
Thirty minutes with the founder
Bring the prototype or the system you already run, under NDA if you prefer. You leave with a recommended way of working together and the reasons for it. If we are not the right vendor, you hear that too, with a pointer to who might be. No team pitch and no rate in that call.
Or write below. We reply within 48 hours.
