Just came across Lofty via Angellist and downloaded the iOS app. Interesting idea targeting stuff that's "too expensive for eBay, but not expensive enough for Sotheby's".
I found Lofty on angel.co, tried it out. Bought a painting for a great price. Had some minor customer service issue but the company was super responsive and helpful and worked it out. I'm a fan.
