In 1999, we win a tender for a private Eurotel website for Major Key Accounts with 3,000+ customers.

We venture into wap pages and we prepare a first mobile website for the Nokia 7110 phone. We take care of the mobile platform.


In 2002, we reap success in a tender for development of the page in a Java CMS. The design of the pages is provided by the Siegel and Gale agancy. Thanks to our CMS, we acquire the main page of and we start an era of tens of projects. Until today, we remember the Go Ježíšku Go signature tune.


Eurotel is responsible for a too large part of our profits, which frightens us. We look for another client. In 2004, we compete in a demanding tender for the Český Telecom website, with two tens of competitors. Our jNetPublish brings us victory again. We transform 3,000 PHP pages in two language versions.


We are happy to have two large clients. Yet Telefónica enters the Czech market. For us, this means Eurotel and Český Telecom rebranding.

Once again, we have a single partner. We work on a convergence of all solutions under Telefónica O2, which is a difficult test of both project management and software development, but we go for the kill as a Spanish bull.


We try the job a mover and move servers from Vidoule to Nagano.

We launch launch a new press center, which has been running in 02 until today.


We launch the first version of the 02 Extra loyalty program, a predecessor of today’s well-know Extra výhody (i.e. Extra Benefits).


We work on a successful program by the Nadace O2 (i.e. O2 Foundation), Think Big, which provides financial support to socially beneficial projects implemented by young people. The key part wasn’t frontend, but backend providing an intricate workflow for hundreds of programs.


We introduce website operations on IPv6. We launch a new website, on whose development we have been working in a 30-member team for 8 months. We use state-of-the-art technologies such as CSS 3, HTML 5 and we eliminate the need to use Flash. The website runs on the newest jNetPublish version and integrates many third party solutions (chat, forums, data from CRM/ERP, SSO). Two years later, we started to integrate with the ATG e-commerce platform. Although it was a project extremely demanding in the terms of coordination (inputs from several parties, integration testing, etc.), it was launched on time and at the required quality.


In a consortium with the Datart company and in a record-breaking time, we create a robust B2B portal for O2 corporate clients. On the portal, corporate clients can purchase phones, SIMs with tariffs and services, but also other products such as laptops, tablets, modems, accessories, etc. The portal also offers customer services, such as SIM transfers between different subjects, porting from other operators, claims, possibility to pay with loyalty points, and many other services. Thanks to this portal, O2 was able to replace outsourcing from partners who had provided these services before. For O2 clients this meant a processing change in the direction to full automatization. It is a solution with a lot of integration, its basic version is deployed in only 3 months nevertheless.

We introduce Adobe Search and Promote on Our online solution of O2 Extra Bonuses, the most successful loyalty program in the Czech Republic, enables customers to redeem benefits using webpages or a mobile application. The key technological but also competitive advantage is the fact the solution covers the possibility to redeem benefits using all online channels - SMS (key words), website, mobile website, mobile application.

The online solution of O2 Extra Benefits won the 1st place the Telecommunications and IT category of the Internet Effectiveness Awards competition. A year later, we celebrated success in the same category, this time with a successful implementation of the Soyka personalization tool.


In the O2 Extra Benefits program, we deploy our Soyka personalization tool, thanks to which you choose from benefits which are the most attractive for you and users similar to you.


We launch O2 Videotéka (i.e. O2 Video Library) and O2 TV Go (live broadcast of TV channels with a support for mobile devices). The project is demanding, due to integration with internal O2 systems and with the key platform of the Czech provider, which mediates content also for O2 TV and is therefore the license holder of all DRM-protected streamed material. Together, we face challenges and build a portal which provides services on several platforms (web pages, mobile web pages, smartphones, tablets). For development, the modern internet Play Framework has been used, together with the Scala programming language, which is used for building their solutions by the likes of Twitter or Foursquare. In the area of data storage, the portal uses MongoDB and Redis. Thus, the complete solution provides comfortable and fluent browsing through the movie movie catalog for everyone, even at high loads.

“Etnetera is a partner I can always turn to and rely on. When working on our projects, we really feel as if were a part of a single team. Through cooperation with them, not only our online business grows, but so do I. I hope to find once some more time to learn what else they can do for!”

Aleš Krejčí – Online Development Manager

Aside, we take on a small project, Phone booth adoption, where people can use personal messages to please their loved ones and help “Linka bezpečí” (i.e. Helpline) with a CZK 500 contributor.


Etnetera mobile developers successfully take the O2 Extra Benefits application under their wings (on the iOS, Android, and Windows Phone platforms) and the development revs up. By this step, we close the whole O2 Extra Benefits ecosystem, which includes a website, a mobile website, mobile applications, and B2B applications. Client can find all solutions and all professionals under a single roof. This way, they benefit from the synergy of tools and integrated communication.

“I don’t see Etnetera as a supplier, or an agency, but as a member of our team. A reliable, responsible, and stable member. One who’s an expert in their field and can manage all the work without the agency annoyances. One who always tries to help when help is needed.”
