Custom software
SaaS products, client portals, payments, websites and internal tools. We build from scratch or migrate from what you have. We fix the price after the brief and hand the code over to you.
Status: In production: a booking platform for psychologists for a company in Czechia (development ongoing), a custom CRM for an electronics store chain and a lending pipeline for a non-bank lender.
The problem
- Off-the-shelf builders can't handle your logic: payments, roles, calendars, special rules.
- The previous contractor disappeared or the project dragged on, and you need the product now.
- The site runs on an old CMS, it's slow and breaks with every update, and a move feels risky because you could lose search traffic.
- You have no tech team of your own, but architecture decisions have to be made now.
Prototype and price first, then code.
You see the key screens and the price before development starts.

Who owns the code?
You do. We hand over the code and documentation. The repository, accounts and domains can be on your side from day one.
Will you take over someone else's project or an old one?
Yes. We start with an audit: what exists, what works, what breaks. We've already moved a site off an old CMS while keeping its page URLs, and built a site from a design tool export.
How do you test?
Automated tests on every change, a separate staging environment, and releases to production only after checks there. We review every screen on desktop and mobile.
Do you work with companies in the EU?
Yes. One of our clients in production is a company from Czechia. We work under a contract, with payment in foreign currency to a European bank account.
What happens after launch?
Support by agreement: monitoring, fixes, new modules. Or we hand everything over to your team with documentation.
