What we do
A holding company with an engineer's discipline.
SwartBerg Studio is the parent company of the group. It develops the products, owns them outright, and holds the shares in the companies that grow out of them.
We keep experimenting
New app ideas are tried small and fast. The ones people want become products; the rest teach us something.
We hold the group
When a product grows into a company of its own, SwartBerg Studio holds the shares as the group's parent company.
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, or become a company of its own.
