logo: I’m pretty sure it’s a custom job - the shape of the “o” isn’t really something any self-respecting font designer would do. But it works ok as a logo, as it’s pretty much all geometrically constructed letterforms.

rest of site: I haven’t compared it against samples, but I get a strong vibe of Chalet, fairly heavily modified. Could be one of a number of other similar sans serifs, or (possibly) a completely custom job, though.
