Custom Licensing

The revenue-share-based model suits games but it might be harder to pick by the other industries. To overcome this, we offer custom licensing options that can be suited for a specific client. This includes options for per-seat licensing (paid monthly/yearly) or a flat fee (eg. per project). The actual price depends, for instance on the development team size or the target users of the product (eg. in-house tool, 3rd-party client, SAS, etc.). If you’re interested in custom licensing options feel free to contact us.
