Fair Warning
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.
Kindred
Kindred is a members-only home-swapping network that turns primary residences into a credit-based travel platform. Founded in 2021 by Opendoor alums Justine Palefsky and Tasneem Amina, the San Francisco company has grown to nearly 300,000 members across 150+ cities and raised $125M in combined Series B/C in February 2026 to scale a 'third way' alternative to hotels and short-term rentals.
