LuminAID, the solar-powered light start-up that won our 2012 John Edwardson, '72, Social New Venture Challenge, is back on SharkTank. LuminAID cofounders Anna Stork and Andrea Srestha returned to ABC's hit show to offer viewers an update on their progress since they struck a deal with celebrity investor Mark Cuban on the show in February 2015. We won't spoil the surprises, but let's just say the future continues to be bright for this social venture (sorry, we couldn't resist!).
