Loren Brill, 28, founder and CEO, Sweet Loren's
Three months out of college, Brill was diagnosed with stage 2 Hodgkin's lymphoma. Facing six months of chemo, she moved home to New York City and plunged into baking, a lifelong hobby. Word of mouth about her creations took off, and in 2011, Brill, now healthy, launched Sweet Loren's, a line of all-natural, preservative-free cookie doughs and brownie batters.
