Fair Warning is a New York-based, members-only art auction platform founded in 2020 by Loic Gouzer, the former Chairman of Post-War and Contemporary Art at Christie's. Rather than staging sprawling sales, Fair Warning sells one carefully chosen lot at a time to a screened community of collectors through its mobile app, where bidding happens with a swipe. The company positions itself as a leaner, more transparent alternative to legacy auction houses, charging a flat 15% buyer's premium and building a catalogue around artists it has conviction about.

Kenneth Schlenker is a French-American serial entrepreneur and the founder and CEO of Opal, the #1 screen time and focus app on iOS. He first envisioned a focus app in 2008 while working at Google - it took him 11 years to actually build it. After founding art-tech company ArtList (acquired by artnet), launching Bird's Paris operations, and building a $10M ARR business with just 11 people, he also runs Open Scout, a weekly newsletter covering early-stage startups read by investors at Sequoia, YC, a16z, and Accel.
