We own what we operate
Most of our projects are not client work but our own businesses. We carry the investment, the risk and the day-to-day responsibility for keeping them running.
Quest Group a.s. — Prague, since 2001
For twenty-five years we have built products and companies — first for mobile operators, publishers and international brands, today mostly our own. The newest is ONE: a new restaurant concept where each location does one dish and perfects it.

How we work
Most of our projects are not client work but our own businesses. We carry the investment, the risk and the day-to-day responsibility for keeping them running.
Decisions are made by people who stake their own name and their own money. There is no layer between the decision and the work.
The same company, the same leadership and, since 2012, the same registered office. Financial statements are filed in the collection of deeds properly and on time.
What we've built
We have ridden every technology wave the same way: a small team around a specific product — build it, launch it, run it. Food is the next chapter, with the same approach.
2001

In 2001 we built the first mass-multiplayer mobile game on SMS for Eurotel (now O2) — more than 300,000 people played it. Four years of product work followed: mobile internet, photo services and content distribution in the days before the App Store.

When the iPhone and iPad changed media, we built native products for major German publishers: four paid apps for Rheinische Post, RP+ — one of the first iPad-only weeklies — and four apps for DIE ZEIT.

JudRobot tried bringing machine intelligence into legal practice before language models were ready for it. A year later we built a mortgage platform that cut the journey from scanned document to loan approval to ten minutes.

Ctrl AI gives corporate AI its rules: it connects a company's documents to language models so that every answer can be traced to its source. At the same time, investors from the United States are joining the group — and the path toward our own restaurants is opening.
2025–
Persistent story worlds for zoos, museums, science centres and heritage sites. Technology, cinematic craft and real places in one venture.
2026–
A new restaurant concept: each location does a single category of food, from fresh ingredients only, at a price held down by the simplicity of the operation. We are looking for a flagship location in Prague.

References and our own companies
Alongside our own ventures, we spent years building products and campaigns for major clients. Two of those brands are in food.
Internal software development
Systems for the internal operations of the country's largest quick-service chain. That is where we learned how food businesses plan shifts, manage stock and measure a location's performance.
Marketing
Marketing for an international coffee chain — a brand that has to work equally well in every single location.
Our own company — ctrlai.com
A US company owned by Quest Group. It builds the control layer between company documents and language models — every AI answer traceable to its source.
Product leadership, mobile internet
Nearly five years of product work through the transition from GSM to smartphones.
Native apps and publishing platforms
Five and a half years of digital transformation for a print publisher.
Native mobile apps
Four years building apps for one of Germany's most respected weeklies.
For landlords and partners
We are looking for a flagship space for the first ONE restaurant. Here is who you would be dealing with — and what you can verify about us before the first meeting.
Quest Group has been on the commercial register since 2001, has fully paid-up share capital of CZK 2,000,000 and financial statements for 2022, 2023 and 2024 duly filed in the collection of deeds. In twenty-five years it has never been in insolvency or liquidation.
We developed internal software for McDonald's Czech Republic and did marketing for Costa Coffee. We understand shifts, stock, food cost and location performance — we built those systems and communicated those brands.
We have property development behind us. Building works, equipment, ventilation, occupancy approvals and dealing with the authorities are nothing new to us. We enter a space with a design, not with improvisation.
The project is financed from our own resources. The group owns the US company Ctrl AI, Inc., and investors from the United States are joining the company — including partners with their own American restaurant experience.
We did not invent the short-menu restaurant. It has worked for years in Budapest, Zurich, London and California. We are bringing it to Prague with our own brand and our own operating system.
You deal directly with the chairman of the board — the person responsible for the project. No chain of intermediaries, no asset-free operating company founded a week before signing.

Do you have a space that could be ONE's flagship? Or would you like to walk through the concept in detail? We are glad to show the unit economics, the design for the space and the opening timeline.
