FAQ

Common questions.

Didn’t find your answer? Write to us - we reply personally.

Why Grumium, and why the dragon?

Grumium is the star ξ Draconis in the constellation Draco, the Dragon. Ptolemy described it as the star on the dragon’s jaw, and the name comes from the Latin grunnum, “snout”. The Dragon coils around the north celestial pole and never sets — just as we take a product from the first idea to launch and beyond, and don’t disappear after release.

How much does a website or app cost?

It depends on scope, pages and integrations. After a short brief we send an estimate broken down by stage - no hidden costs.

How long does it take?

A landing page takes about 2-3 weeks, a website or store 4-8 weeks, an app from 8 weeks. We agree the exact plan during discovery.

What do you need from me to start?

Fill in the brief or write a few lines about your idea. Then a short call, and we come back with a plan, timeline and estimate.

Do you support the project after launch?

Yes. Updates, monitoring, fixes and new features - as agreed, in a format that suits you.

Who owns the code and design?

You do. After payment we hand over the repository, access and design files.

Do you work with clients abroad?

Yes, we work remotely in Ukrainian and English.
