Employee-Owned Structure & Revenue Sharing

At Supono Holdings LTD, we operate under an employee-ownership model, meaning that every team member benefits directly from the company’s success. In addition to a competitive fixed salary, all employees participate in our revenue-sharing program, ensuring that contributions to the business are rewarded fairly and transparently.

We expect Flutter developers to ensure projects are completed and launched within 1 to 2 weeks from scratch. You may need to work with dummy APIs during API finalization to maintain progress and meet deadlines.

We value developers who can self-manage and adapt quickly to dynamic workflows. For instance, a typical request might be: “Build an app like this competitor.” If Figma designs are not yet complete, you should be able to identify key components and begin structuring the app to ensure efficient progress while waiting for finalized designs.
