What we do
A product company with an engineer's discipline.
SwartBerg Studio designs and develops its own products, owns them outright, and supports them for the long term.
We keep experimenting
New app ideas are tried small and fast. The ones people want become products; the rest teach us something.
We keep improving
Products stay with us after release. We maintain them, support them and keep improving them for years.
How we build
Principles we do not trade away.
Clean architecture
Clear boundaries between domain, application and infrastructure, so systems stay easy to change years after launch.
Measured, not assumed
Automated tests, benchmarks and real numbers decide when something works. Optimism is not a test strategy.
Secure by default
Authentication, validation and privacy are designed in from the first commit, not bolted on before go-live.
Built to keep
Readable code, documented decisions and repeatable deployments, so a product can keep growing for years.
