We used to run the Friday Free Fonts series of posts in the past but finding free fonts are not that easy. We understand the level of work necessary to design a font and good work is not always free.
Kallan & Co, Paul Russell, Brett King and Hannu Koho share a beautiful typeface design project on their Behance profile. The font created is called AppD Sans and it was designed in conjunction with the rebrand of AppDynamics by Cisco.
They also worked with Göran Söderström from Letters From Sweden on the type design and the result is truly beautiful. I personally love the details and the typography applications.
