05Frequently asked questions

Frequently asked questions

Web or mobile app for a startup?

A web app is usually faster to launch and change. Mobile makes sense when usage happens mostly on the go.

Do I own the code?

Yes. The code and data are yours, which matters to investors and your future team.

Can you help prioritise features?

Yes, that is the point of scoping: keep the essentials and postpone the rest.

How long to launch?

We aim for a live first version in six to eight weeks for an MVP, and three months at most.

Does your startup need its product?

Tell us your idea and we'll suggest the first version to build.
