Hey, this font is now being used on so many big name companies letters (this one is from google / 123Reg), and I've been trying to figure what the font is.

It looks identical to Corbel and Calibri, but it looks thiner. Can't seem to find a variations on these fonts which matches, any ideas?

Thanks.
