About Us
A software company since 2018
WIARA DAAS EOOD (WIARA) was founded on 30 November 2018 in Plovdiv, Bulgaria (VAT BG205417373). For more than seven years we have built custom software — web and mobile applications, cloud infrastructure on AWS, integrations and automation — for clients in Europe, the United States and Asia.
The DigitalProductPassport platform is our product since 2025: the first complete Bulgarian solution for the Digital Product Passport, published in eleven languages, prepared for the EU registry (we work in its test environment and the production connection is being built) and demo passports shown on national television. We are certified to ISO/IEC 27001:2022, a member of the Ruse Chamber of Commerce and Industry, and we publish partnership offers through the Enterprise Europe Network.
The DPP is new to everyone — the regulations date from 2024–2026. The company behind the platform is not.
WIARA is a Bulgarian company dedicated to implementing innovative digital solutions in support of sustainable development and business modernization.
We believe that technology is the key to a more transparent and competitive economy, and we work to help businesses stay one step ahead.
The proof of our professionalism is our certification under the international information security standard ISO/IEC 27001:2022 (Reg. No. BG2026030401). It confirms that we manage information security to an internationally recognised standard, with independent verification.

Today, from Bulgaria, WIARA is making its biggest bet with an innovative Digital Product Passport (DPP) platform, turning EU regulations into a powerful tool for industrial transparency and sustainability. His vision is to build an environment for top talent that creates smarter, more agile companies — where technology amplifies human potential instead of replacing it.

You can reach us directly or through your local EEN partner.

Seven employees, scaling with contractors on larger projects. Small enough that you will speak to the people who build the thing, which is the point rather than an apology. The three you are most likely to deal with are on this page, with what they actually do.
