‘Maruta Wachta’s team has deep knowledge about the specifics of the technology, media, and telecommunication sectors. My company delivers IT services and applications, so for us its crucial to have legal support (e.g. during formal contract negotiations) from a partner who understands what IT project methodology is, what are the key risks during system development, deployment, and maintenance. And on the other hand, a law firm has to understand sometimes very specific contracting rules that apply to the institutions of TMT sectors. We had a chance to cooperate with several law firms and the quality of services by Maruta Wachta was absolutely above the average.’
