Inc. Mag­a­zine pro­files 18 entrepreneurs/CEOs, all of whom are under 30.

This gen­er­a­tion, at nearly 80 mil­lion strong, is poised to be the largest, the most edu­cated, and the most diverse in Amer­i­can his­tory. That gives its mem­bers spe­cial insight into the largest, the most edu­cated, and the most diverse mar­ket in his­tory. They are also fear­less about tech­nol­ogy. The kids of the ‘80s grew up with com­put­ers; the kids of the ‘90s can’t recall (and shrink from imag­in­ing) life before the Inter­net. And they are ide­al­is­tic and opti­mistic — traits that influ­ence their per­cep­tions of business.

Mil­len­nial entre­pre­neurs are a breed apart from those who came before. The ways in which they start com­pa­nies — and the com­pa­nies they start — reflect those distinctions.
