I believe it's Avenir.

Well, they're cousins, at least:

Might be Avenir Next. And the designer could have customized it a bit (e.g. the terminals of the C).

Good call on the Avenir family. To be more specific on which font was customized though, it appears most likely to be Avenir Next Demi.

It's really close. The RUBI looks like Avenir Next with some very minor structural differences (the leg on the R starts farther out in the original and has a different angle, the curves of the U are flatter, the upper bowl on the B is shorter). What could cause that?

The CON, though, looks a lot more like Myriad than Avenir, with some alteration on the C.

Gotham Narrow, I’d say (with customised C).

I just had the same idea, only I just changed the C to Gotham and cut out a bit from it:

I don't have Gotham Narrow. :(
