About Devx

A Czech software company, Devx runs digital product projects end to end, from the first analysis to the support that follows launch. It says it works as a long-term partner for companies that want strong digital products, and that it holds ISO 27001 certification for its information security management system. Its team has its roots in Silesia, and the firm describes its developers as the engine behind its work.

A hidden partner for agencies, under their brands

For years Devx worked as a development partner behind European advertising agencies, delivering projects under the agencies' own brands. The firm describes this white-label model as a way to reach work that small technology agencies would not win alone, and says it keeps its teams current with new technology.

Platforms, apps and portals

Its portfolio includes web applications, from portals and management systems to data hubs, as well as Android and iOS apps. One is an information app for the Pardubice VI municipal district, which puts local information in one place for residents on their phones. Other projects include a platform for online psychotherapy, a platform for a housing cooperative, a policy portal for an international research institute, and an e-shop.

Certification, ongoing support and nonprofit work

The firm holds official partner status with an e-commerce platform and provides ongoing support and maintenance after launch. Its clients include a counselling and education organisation for helping professionals and seniors, and a nonprofit association that runs leisure and residential activities for children and young people with disabilities. The company says it is regularly recognised for the quality of its projects and for client satisfaction, and that it manages each project to high standards and certifications. Its site describes one service running from the first analysis to continuous support, with long-term partnership as the aim.
