They are a subsidiary of Atlantic Media Group that are explicitly advertised as no pay walls, no registration, and no app downloads:

Atlantic Media is owned by David Bradley and Laurene Powell Jobs invested in The Atlantic recently (but I think all of the subsidiaries are still owned solely by Bradley).

Before he was in media, he founded and sold a few advisory companies that went public, where he made a few hundred million dollars. So I guess Quartz's business model is live off the largesse of very wealthy benefactors?
