Moti Shniberg shuffles through the lobby of the trendy Manhattan building where his company is based to a quiet corner table. A boyish 41-year-old with red hair and a soft Israeli accent, he’s slightly out of place among the dressy-casual office workers who weren’t yet in high school when he launched the Artist Pension Trust, which may hold the largest private collection of contemporary art on the planet.

“Look around,” Shniberg says, gesturing to the walls. “You see all the art there? All of these are APT artists.” And who created the video installation in the corner? “I’m not sure,” says Shniberg, half sheepish, half defiant. “We have so many artists.”
