Looking for the font of this lawfirm: http://www.lppvlaw.ch/?lg=en 

It is posted as image so my font-detector add on can not find it. 

Can anyone help me find out witch font it is?

Here is close looking font, not exact but close: http://www.myfonts.com/fonts/kostic/roc-grotesk/wide-medium/

The fonts the law firm use are called Blond and Blondine by Aurèle Sack. 

I assume those are custom designs not available to the public. You might ask the designer for more information: http://www.aurelesack.com/

They look like the yet unreleased LL Grey.

Other than the aforementioned Roc Grotesk, also Bureau Grot shares some similarities.

It has been used by others, specifically the Institute of Contemporary Art at the University of Pennsylvania:

Thank you 🙂
