Is there some name to this style? I'm seeing it more often these days, but just can't nail it down to a framework or so...

I see a mix of flat and material design, but I'm not sure it has a name like Brutalist does. One should probably come up soon given how nice it is. I really like the Rubik font here.

Replacing borders with drop shadows seems to work out great - plus light background with some really delicious colors. Reminds me of Stripe design.

I agree. I'm using a similar design in a current pet project (http://www.niche.fm), it's fun. I still need to update the old lightpink + #181818 modules, though. :)

Yeah, the design is really great! The only thing that slightly (as slightly as one can imagine) put me off are the sharp corners on the "Side project collective" box, while everywhere else are those nice round corners. It may be just me, though, just my two cents.
