Michaela P.Coaching client from the tourism industry (translated from German)
Discretion is fundamental to the way I work. That's why many coaching clients remain unnamed, and what we discuss stays between us.
From global companies to startups
My clients range from international corporations such as voestalpine, Henkel and Ingram Micro, through public-sector organisations such as the City of Vienna and the State of Lower Austria, to startups and individuals preparing for the most important talk of their careers. What they all have in common: they didn’t just want to look good, they wanted to win people over.
I have spoken at the E-Day of the Austrian Economic Chamber, at the inno x network and at the Digital Didactics congress, among others. You’ll find all my talks on the keynotes page.

Frequently asked questions
Which companies has Michael Sinnhuber worked with?
More than 150, including voestalpine, Henkel, REWE, BILLA, Porsche Austria, DAIKIN, Ingram Micro, Bank Austria, Helvetia, Salzburg AG, Greiner Group, Böhler Edelstahl, SunExpress and the Hofburg Vienna. Public-sector clients and associations include the Austrian Health Insurance Fund (ÖGK), the City of Vienna, the State of Lower Austria, the Austrian Federal Ministry for European and International Affairs and the European Handball Federation.
Do you only work with large companies?
No. I work just as often with individuals, the self-employed and startups, for example before a pitch, a job interview or an important speech. Public speaking coaching is for you personally, the team workshop is for your company.
Is working with you confidential?
Yes, always. Discretion is fundamental to the way I work: what we discuss stays between us, without exception. The same applies to any documents, figures and internal information we work with.
