FAQ

Questions about websites and apps

Can you take over my current website?

Yes, if we can get the access. We keep existing page addresses or set up redirects, so you don’t lose your search rankings.

What happens after launch?

You edit your texts yourself. For changes and maintenance, support starts at €290/month, with no minimum term.

Do you use WordPress?

Rarely. We prefer static sites, faster and safer, with no plugins to update. If WordPress is a must for you, we discuss it during the diagnostic.

Do you build mobile apps?

We build web apps that work on mobile, without going through app stores. That covers most internal needs.
