Former Christie's co-chairman Loic Gouzer knows a thing or two about auctions. Instead of hosting big events, his new project, Fair Warning, is doing things one at a time. Specifically, it's auctioning off one piece of artwork every week, with the sale starting on Sundays at 5 pm ET. Its app is similarly simple, with the ability to explore the available lot, bid, and manage account details. Currently invite-only.
