GDPR-Compliant Software Development for EU Businesses
Teamseven builds custom software, SaaS platforms, and mobile apps for businesses across the European Union, data handling built around GDPR principles, hosted in the EU where you need it, and shaped around the data-protection standard your market actually demands. We designed and built Rezi24, a healthcare platform hosted on German data centres.
No commitment. Response within 24 hours.
Software we've built for EU and international clients
Why EU teams come to us
If one of these is your situation, this is how we handle it.
You need a partner that treats GDPR as architecture, not paperwork.
GDPR designed in from day one. Data minimisation, consent, right to erasure, audit trails, and EU data residency where it matters. We built Rezi24, a GDPR-compliant German healthcare SaaS running on German data centres.
A local agency rate makes the whole project unviable.
Senior engineers at a fraction of the local rate. CET overlap for standups and reviews, EUR invoicing, and the same professional standards. Fixed-price, scoped before we start.
Off-the-shelf software fits most of your process, and the rest is spreadsheets.
We build the platform that fits. Custom SaaS and operations software modelled on your real workflow, with EU payment and identity integrations.
A previous build stalled and the team is gone.
We audit, then take over delivery. A straight assessment of what is salvageable, then fixed-price phased recovery. See software project rescue.
Built by AI-native engineers, so AI is a feature ticket, not a rebuild
Every build we deliver for an EU client is architected so language-model features go into your data and workflow when you want them, GDPR-compliant and on EU infrastructure where it matters. We design the schema, APIs, and event streams for it from phase one. It is how we built our own products, Tully AI and Mebag.
In-app copilots, drafting, and summarisation wired into the product your team already uses, with humans in control.
RAG over your records, so a plain-language question returns a grounded answer.
Multi-step workflows wired into your systems, with guardrails, evals, and human approval on anything sensitive.
Shipped with prompt versioning, eval suites, and guardrails. See how we build AI →
Why EU businesses choose Teamseven
Custom software done right for the European market: data protection built in from the first line of code, EU hosting where you need it, and a team that treats compliance as architecture, not paperwork.
GDPR principles built in
Data minimisation, consent handling, right-to-erasure, audit trails, and EU data residency are handled according to your data-protection guidelines from day one, not retrofitted after a review. It's how we built Rezi24 for the German healthcare market.
CET-friendly working hours
We keep meaningful overlap with the European working day, morning stand-ups, sprint reviews, and same-day answers in real time, not on a delay. And we build multi-language interfaces (German, English, and more) where your product needs them.
EU hosting, offshore value
We deploy to EU-based cloud regions, including German data centres, so your data stays in the EU and is processed to EU standards. Senior-engineer quality at a fraction of a Western-European agency day rate, invoiced in EUR.
Software services for EU businesses
Every block is a service we deliver end to end for EU businesses, GDPR-aware and fixed-price, scoped before we start.
GDPR-Aware SaaS Development

Learn moreHow an EU build actually runs
The same track on every engagement. You always know which phase you're in and what unlocks the next one.
Scoping & data-protection review
A 30-minute working session in CET morning hours. We map the problem, the outcome, and which data-protection requirements apply, then send a fixed-price proposal, usually within two working days.
Kickoff & onboarding
A kickoff call with the engineers doing the work. Access and accounts set up in week one, a shared Slack channel, and an agreed weekly rhythm in CET-overlapping hours.
Design & GDPR architecture
Scope turned into screens, a data model, integration points, and hosting decisions, with data minimisation, consent, and EU residency designed in. You review and sign off before code starts.
Build & weekly review
Development in weekly cycles, twice-weekly written updates, and a working environment you can click through. Scope changes are documented and priced as they happen.
Launch on EU infrastructure
Production deployment to EU cloud regions, including German data centres where required, with CI/CD, monitoring, and error tracking. Full Git access and two months of free bug fixes.
Iterate or hand off
Most clients move to a monthly retainer for the next features, prioritised against real usage. You can also take the codebase fully in-house, or pause.
Built for Germany. Hosted in Germany.
A healthcare platform we designed and built around GDPR data-handling principles for the German market, our first EU engagement, delivered end to end.
Rezi24, Online Reception for German Doctors' Offices
Rezi24 gives German medical practices an online reception: patients book appointments 24/7, reception teams field far fewer routine calls, and everything runs on German data centres, built around GDPR and EU data-protection principles. Public practice website, patient booking, and a full provider dashboard, services, locations, treatments, patient management, and internal chat, in one connected platform.
Designed and built from scratch by Teamseven, and built to be run by a non-technical practice team. Launched at rezi24.de with a 5.0 rating verified by Trustindex. The platform is currently on hold while the client works on how it's marketed, the build and the data-protection approach behind it stand regardless.
Building software for the EU market?
30 minutes, in CET morning hours. We'll give you an honest read on the compliance and hosting approach before anyone quotes a number.
Book a scoping callThree ways to engage us
A founder with an idea, a business with a roadmap and no hands, and a team stuck with a stalled build need different things. Pick the one that sounds like you.
Fixed-Price Build
You know roughly what you need. We scope it, quote a fixed price and timeline, and build in stages with a working demo each week.
Fixed-price and MVP buildsYou have a team, not enough handsStaff Augmentation
You have engineers and a roadmap but need senior developers who built Rezi24 for the German market embedded in your team, in CET-overlapping hours.
IT staff augmentationYou inherited a stalled buildSoftware Project Rescue
A previous team is gone and the build stalled. We audit what exists and tell you honestly whether to extend, refactor, or rebuild.
Project rescue and modernizationCommon questions from EU clients
Do you build GDPR-compliant software?
Yes, we build data handling around GDPR principles from day one, not as an afterthought. Data minimisation, lawful basis and consent handling, right-to-erasure, audit trails, encryption in transit and at rest, and EU data residency where required are part of our standard delivery for EU clients. We built Rezi24, a healthcare platform for the German market hosted on German data centres, to those principles.
Can you host our software in the EU / in Germany?
Yes. We can deploy to EU-based cloud regions, including German data centres, so patient, customer, and user data stays within the EU and is processed to EU data-protection standards. For our German healthcare client Rezi24, hosting in Germany was a founding requirement, and we built the platform around it from day one.
Do you accept EUR payments?
Yes. We can invoice in EUR and accept international bank transfers with no conversion overhead for EU clients. We work with clients across the US, UK, Australia, and the EU.
How do you handle time zones and language for EU clients?
Pakistan is GMT+5, giving us meaningful overlap with the European working day, we start as the CET morning begins, so stand-ups, sprint reviews, and same-day responses work in real time rather than on a delay. Our team works in English, and we build multi-language interfaces (for example German and English on Rezi24) where a product needs them.
Can you build AI features into our software?
Yes, and we architect for it from the start. Our engineers are AI-native: LLM features, RAG over your own data, and agents that take actions all drop in as a feature ticket rather than a rewrite. When we build AI in, it ships with prompt versioning, eval suites, and guardrails, and data is handled to GDPR on EU infrastructure where it matters. It is the same approach we used for our own products, Tully AI and Mebag.
