sans serif in pentagram project

trying to figure out the type in pentagrams identity for grant thornton. the 'a' reminds me of universe while the 'g'seems a bit more like avenir or gotham.

oops i mean gotham, not gothic

Sounds like it's custom: "The logo also features a custom-drawn wordmark designed in collaboration with type specialists Dalton Maag."

Also, no "e" in Univers.

If you're a fan of the 'a' check out Neuzeit S.
