The Inc. team weighs the merits of a building a social mission into a company. Is it really best for the world—and especially for shareholders? They also discuss the origin and growth of one company that’s recently been lauded for giving back to the world: LuminAid, the maker of a solar-powered inflatable lantern useful in disaster-recovery. Also, the team talks with Ryan Frankel, the co-founder of VerbalizeIt, about how he executed the company’s sale to Smartling.
