We develop and operate our own digital products in real estate, automotive and infrastructure — and engineer custom systems for companies that need software to work reliably for years.

Figures as published on realitnibalicek.cz and irest.cz, November 2026.
Platforms we build, own and run every day — one established portal with a full toolset for real estate professionals, and three newer products built for international markets.
Enterprise applications, architecture and integrations, modernization and long-term operation — for companies that depend on their systems, delivered by the team that runs our own products.
Each product has its own brand, website and audience. Development, operation and long-term care stay with DALTEN.
Czech real estate portal
Property search for the public, listings for agencies and developers, and data around each property — location context, price history and valuations. On the market for more than 20 years.
Connected services iRest · REWEB · Agent websites · WebNem · RMIX MLS · Valuations
Market: Czech Republic · Language: Czech
European property search
One search across countries, with listings from all over Europe in the user’s own language.
Digital identity for cars
A permanent record of a car’s life — history, documents and photos that can pass to the next owner.
Infrastructure monitoring with context
Learns each server first — hardware, services, disks, storage and VMs — then watches only what matters.
Around RealityMIX we develop and operate a set of services for agents, agencies and developers. A property entered once in iRest is exported to portals and to the agency’s own website; agent websites are built from RealityMIX profiles; valuation reports draw on RealityMIX data.
Listings, clients, inquiries, teams, tasks and calendars in one system, with export to real estate portals and websites. Developed since 2007.
400+ agencies · export to up to 24 portals
Ready-made websites for real estate agencies with their RealityMIX listings, hosting and HTTPS — including a variant for development projects.
A personal website for each agent, generated from their RealityMIX profile with current listings, on the agent’s own domain.
A standalone website for a single property on its own domain, used for sales campaigns.
Sharing of public, private and pre-market listings between agents, so they can cooperate on deals.
Price reports for listing appointments built from RealityMIX data, plus web modules that collect valuation requests from property owners.
Realitní balíček brings these services together into a single offer for agents, agencies and developers.
We design, build and operate software for companies whose systems carry real business logic, real data and real users — and that need a partner who stays responsible long after launch.
We take on projects where engineering quality, long-term reliability and business value matter more than the lowest initial quote.
Applications and information systems designed around how your company actually works, not around a template.
Operational and business systems with complex logic, large amounts of data and many user roles.
Architecture design, APIs and integrations that connect applications, data sources and external services.
Taking over existing systems, stabilizing them, and developing and modernizing them step by step.
Deployment, monitoring and long-term operation of production environments — the same work we do every day for our own products.
We start with processes, data and constraints. Technology choices follow from them.
Performance, security, monitoring and maintainability are part of the design, not a later phase.
Our client systems have run for five to more than fifteen years. Long-term development is the normal case for us.
Clear trade-offs and honest timelines instead of promises made to win a tender.
We are not the right choice for low-budget brochure websites or one-off campaign microsites.
Typical stack in current projects: PHP · Symfony · relational databases · REST API · Linux · containers
Alongside our own products, we have built and run core systems for major real estate companies — each of them for many years. Our own products, operated daily, are the other half of that record.

DALTEN media is an independent Czech software company based in Prague, working for clients and users in the Czech Republic and abroad.
We have been on the market for more than 20 years. Since 2007 we have developed and operated our own real estate systems, and over the same years we built and ran internal systems for major real estate companies. Today we focus mainly on our own products — in real estate, automotive and infrastructure monitoring — while custom engineering remains a full part of what we do.
We work as a development team that owns its results: we design the system, build it, run it in production and keep improving it.
Describe the situation in a few sentences. We will get back to you and tell you honestly whether we are the right team for it.
