We take the of your team.
Web applications, integrations and AI features, built the way you already work: extra developers inside your agency, a white-label team behind your brand, or a partner building your product with you.
01 · Inside your agency
We become part of your team.
More work than developers? We join your stand-ups, your repository and your process, with a named person and an agreed scope.
Brief us as an agency02 · Behind your brand
Your name in front. Our work behind it.
White label means exactly that. No Leveloper logo, no contact with your client unless you ask, delivered on your schedule.
Talk white label03 · Directly with you
Your idea, made solid.
A custom product, an internal tool or an integration no package covers. We start with technical discovery, ship a first version people can use, and keep running it after launch.

Before you write
What people usually ask first.
01How small can a first job be?
A scoped assignment with a written estimate. A few days of work is enough to see how we fit: a review, a bounded feature, a messy integration. We do not sell a retainer on the first conversation.
02Will my client know you are involved?
Only if you want them to. White label is the default: commits, tickets and chat under your agency name, no Leveloper branding anywhere, and no contact with your client unless you ask for it in writing.
03Who do I talk to during the project?
The people doing the work. Every assignment has a named developer who writes to you with status, questions and anything that needs a decision.
04How do you charge?
A written estimate before anything starts, then the assignment is billed as agreed. Agencies are invoiced directly; your client keeps the quote and the invoice they see from you.
05Where are you, and in which languages?
Hungary, in the EU. We work in English and Hungarian, in hours that overlap with Western Europe. Meeting times and availability are agreed before an assignment starts.
06What happens after launch?
Reviewed code and a written hand-over go to whoever works on it next. If you want us to stay, we take on maintenance and the next iterations.
Contact
Tell us what shape you’re in.
A rough idea is enough. You don't need a finished specification, and the first conversation costs nothing. A developer from the team reads your message and replies directly.
