Grounded position

History of our company dates back to 2007. In the beginning as CYBERTEC we designed websites for local and foreign customers. Then we expanded by adding services including server configuration, computer networks, and IT security. In 2011 we transformed into a limited liability company called “k12 sp. z o.o.” and entered the cloud computing branch. Presently we offer cloud software development and the services connected with high accessibility and data security.

Wide experience

We have wide experience in making web services for desktop and mobile platforms. From years we deal with web server configuration in regard to speed and safety. The synergy of the above elements merged with use of the latest technology enables us to develop software fulfilling the world highest standards. Thanks to experience in international projects we are able to finish the most complex undertaking .

Proven innovation

With the latest technologies and trends we choose what is best and use in our projects. This ensures that our solutions stay on top for a long time and are pleasurably to use. In k12 we use innovation everywhere, from project management methods, through hardware on which we work, to the technologies used. That innovation has been confirmed, our project matters24 won the competition for e-startup under the Innovative Economy 8.1 project financed by the EU.

Continuous development

We treat every project as a challenge and an opportunity to gain more skills and experience. In addition to developing websites for clients, we also create our own products. In 2013, we developed an app called iKancelaria24 enabling internet file sharing in law practices. In May 2014 we are going live with our new app called matters24 for law firm management in the Cloud. In 2015, we plan to enter the NewConnect, a Warsaw Stock Exchange public market for innovative companies.

Our software is characterized by functionality, speed, security and the esthetics.
