I've put my money on lettering on this forum before, where it was actually a font. But this looks like (illustrator/vector drawing app) lettering. In case you are looking for a font with similar qualities (interlocking figures, geometric, light, sans serif) ITC Avant Garde is the godfather. You may also like Sharp Sans No. 2 or Bague Sans.
Here's a sample of Avant Garde with alternate A's, spelling PAPAPOLO.
