Klout Font

Klout was a website and mobile app that used social media analytics to rank users according to their online social influence. It was shut down by its parent company Lithium Technologies in 2018.

It is likely that the Eurostile Bold font was used for the website's logo. Eurostile is a square sans serif typeface created by Aldo Novarese in 1962. Additional information about the font can be viewed here.
