Software, built stone on stone.
We design and build web and mobile products, automate the work around them, and keep both running. A small team, one stack we own end to end, in English and German.
Building Wohnster, a platform for landlords and tenants. Currently in development.
Taking on new projects from January 2027.
What we build
Six ways to work with us. Each comes with the stack we would use and a line on when it is the right fit.
Web product development
Customer portals, dashboards and internal tools in Next.js with a Kotlin or Node backend, built to be run and extended for years.
Mobile apps
iOS and Android apps that share the backend with your web product, so one login, one data model and one release process serve both.
MVP builds
A first version with real users in weeks, not quarters: the smallest product that answers your open question, on a foundation you keep.
Product partnership
We stay after launch: a fixed monthly capacity for features, maintenance, upgrades and the questions that only come up in production.
Compliance-aware delivery
GDPR, data residency and audit trails are designed in from the first sprint: EU hosting, role-based access with Keycloak, documented data flows.
AI-augmented delivery
How we work, not what we sell: AI tools draft, test and review alongside us, so a small team ships at the pace of a larger one, with every change still read by a person.
Automation as a service
The steps your team repeats every week between tools, spreadsheets and inboxes become small, monitored workflows. We build them, run them and hand you the dashboard.
Data that moves itself
Sync customers, invoices and tickets between your CRM, accounting and support tools, with a log of every change.
Reports on schedule
The Monday numbers assembled from your systems and delivered to the right people, before anyone opens a spreadsheet.
Approvals and notifications
Requests routed to the person who decides, reminders when they stall, and a record of who approved what.
A small team that owns the whole stack
What that means in practice, next to how a typical agency engagement runs.
- You talk to the people who write the code. No account layer in between.
- One stack we know end to end: Next.js, Kotlin, PostgreSQL, Keycloak, Docker, Cloudflare.
- Working software every two weeks, on a staging address you can open.
- The repository, the infrastructure and the documentation are yours from day one.
- AI tooling in our workflow, a person responsible for every line.
- Project managers relay your questions to a team you rarely meet.
- Whatever stack the available developers happen to know.
- Milestone demos months apart, with slides in between.
- Hand-over at the end, if it is in the contract.
- Headcount as the answer to every deadline.
