A small studio with a narrow focus.

Grafena Dev is a product studio based in Batam, Indonesia. We build our own products and look after them for the long run, rather than taking on client projects.

We pick problems we can see up close: a cashier losing a sale because the Wi-Fi dropped, a stall owner reconciling revenue share by hand at midnight, a streak app that treats a rest day as a failure. Then we build the calm, careful version.

Every product we make is designed to work offline where it matters, to be clear about what it costs, and to keep your data as close to you as possible.
