“One of the best design studios in the design game. Period. Do yourself a favor – fire your designer, and hire these guys.”
“Sergey and the team at Tresor.tech are excellent. Their UI/UX design work is easily the best I’ve found anywhere. Even after testing a handful of other designers over the years, I can confidently say their work is exceptionally strong. I would enthusiastically work with them again for future projects & I’d highly recommend them to anyone”
“Sergey and his team successfully completed a very complex project for us. They have delivered a professional design of International quality as well as nuanced programming for our platform. We also had significant delays with content from our client and he was also very patient with this. We will certainly be using him again in the future.”

We had some changes mid-way through which he accommodated to make sure what we wanted was up to spec and he also provided valuable input from his experience and expertise.

Fixed-scope work runs from $4,500 for a focused piece up to $27,000+ for a full product build. Ongoing work runs on monthly plans from $2,490. Roles, states and billing rules move the number, page count does not.
How long does it take?
A marketing site is 2 to 3 weeks. A product with onboarding, dashboards and billing is 2 to 4 months from first wireframe to launch. Design systems are delivered in stages, so your team can start using the first components early.
Can you build a design system our own team can run?
That is the point of building one. Components with states and rules, tokens, and documentation written for the person who joins after us. If the system needs us in the room to be used, it is not finished.
Can you redesign a live product without churning users?
Staged rollout, one surface at a time, keeping the paths people already know. We watch drop-off between stages rather than shipping a new product overnight and finding out from support tickets.
Can you work alongside our own engineers?
One of our most common setups. Plenty of teams have solid backend and no design competence in-house. We come in design-led, hand off production-ready specs, and take frontend only if your team is stretched.
What about onboarding and activation?
Where most SaaS loses the trial. Empty states, the first useful action, sample data, and the moment the product proves itself — designed deliberately rather than left as whatever the signup form leads to.
