Apercu (officially known as “Aperçu”) is a grotesque sans-serif typeface released in 2010 by Colophon, an independent type foundry set up by UK-based studio The Entente. Colophon describes Apercu as an amalgamation of ITC Johnston, Gill Sans, Neuzeit and Franklin Gothic. The design is full of character and quirks and is easily distinguishable from other grotesques out there. Apercu is available in four weights — light, regular, medium and bold — each with matching italics.
If you are looking for an alternative to Apercu, I recommend checking out Circular and Larsseit. I think Freight Text would make a nice font combination paired with it.
