About Mergus GmbH – Your Partner in Vienna's 1st District

Mergus GmbH at Am Gestade 3, 1010 Vienna: more than 20 years of business consulting experience, transparent company data and personal service for founders and companies – in English and German.

Who we are

Mergus GmbH is a Viennese company for office services, business addresses and virtual office solutions, based at Am Gestade 3 in the heart of Vienna's 1st district. We provide founders and established companies with what they need to appear professional from day one: a serviceable business address, reliable mail handling, a Viennese phone number, a meeting room for important appointments – and consulting that speaks the language of business.

Our company is registered in Austria: commercial register (Firmenbuch) number FN 415372t at the Commercial Court of Vienna, VAT ID ATU68675757. The managing director of Mergus GmbH is Dipl.-Ing. (FH) Ivica Ilic.

Our story

Mergus grew out of more than 20 years of experience in business consulting. Over those years, one observation kept repeating itself: promising founders fail not because of their idea, but because of the administrative hurdles around it – a registered address, official mail, a professional telephone presence, the right legal form. These details decide whether a company is taken seriously by authorities, banks and clients.

That is why we created a service that removes exactly these hurdles: a genuine, serviceable address at Am Gestade 3, mail acceptance with digital scanning, telephone answering under the company's own name and a meeting room for the moments that matter. What began as consulting support has become a complete virtual office – operated by the same team that advises our clients personally.

What we stand for

  • Transparency: clear prices, no setup fees, no hidden costs – and our own company data published openly
  • Legal certainty: a serviceable address (ladungsfähige Adresse) that works for the commercial register, official mail (RSb) and the legal notice
  • Personal service: short paths, on-site support and consulting in English and German
  • Reliability: every letter, every call and every appointment is handled with care and documented

These principles are not marketing for us – they are the reason clients stay with us for years and recommend us to their partners.

Why District 1?

Vienna's 1st district is Austria's most prestigious business address – the home of banks, law firms and internationally active companies. For our clients, a 1010 address signals credibility and established standing, whether they are a start-up in their first year or an international group opening their Viennese office.

We practise what we offer: Mergus GmbH is based at Am Gestade 3 ourselves, between Schwedenplatz and Hoher Markt. We document this location transparently – and we remain personally available to you on site.

For our own daily work, the district also brings practical advantages that benefit our clients: notaries, tax advisers and authorities are within walking distance, which shortens the paths for company formations, contract appointments and official procedures.
