Who are we?

Strategy, design and software under one roof.

We have worked with national brands since 2021. From brand identity to websites, from e-commerce to custom business software, the same team designs and builds every digital piece of the brand. After launch, we keep measuring with real data and keep growing.

FAQ

Frequently Asked Questions

How long does a project take?

It depends on the scope. A corporate website usually goes live in 4 to 8 weeks; e-commerce and custom software projects can take longer. We set the schedule together in our first meeting and keep you updated at every stage.

How much does a project cost?

We have no fixed package prices; the scope and your expectations set the price. Once we understand what you need, we send you a clear quote and timeline.

Our budget is limited. Can we still work together?

We work with everyone from new brands to national ones. If you share your budget openly, we will find the right starting point together and split the project into phases if needed.

Do you outsource any work?

No. Our own team handles everything, including design, software, SEO and content. That keeps quality, communication and the schedule in one place.

What services do you offer?

Websites, e-commerce, custom business software, brand identity, SEO, advertising and social media management. We also take care of maintenance and updates for live sites.

What are your payment terms?

For most projects, 50% is paid upfront when the project is approved and the remaining 50% before delivery. For large or long-term projects, we can split payments into stages.

How often do we meet during the project?

As often as you need. At the end of each stage we review progress together and get your feedback, so you never have to ask "where are we?"

Can we set up a phone or online call?

Of course. Just write to us with times that suit you, and we will plan a phone or online call.
