Jane Siebels' Green Cay Asset Management is known for short selling unethical companies in an effort to bring about change. Meanwhile, to find companies with values that she'd like to support, Siebels dives deep, finding organizations that other impact investors might overlook and, through an innovative online contest, crowd-sourcing in-depth research by local analysts to get at what's happening on the ground.

At Green Cay, Jane Siebels’ top priority is making money for her clients, but she’s also eager to influence corporate ethics. “By telling companies that we’re shorting them, that’s the key,” she says. “That’s where we effect social change."
