The 30 companies (and their young founders) on our 2017 list have been pulled and prodded, picked at, and pondered.
And still they stand — thanks in large part to novel business models, in-demand products and services, and revenue to back them up.
Indeed, these young firms represent the best of what this next generation has to offer.
But they have a long way to go. After all, every big business was small once.
Here, we pulled together some of the best advice from this year's 30 Under 30 judges, who include: Real estate mogul and Shark Tank co-host Barbara Corcoran, XPrize's Peter Diamandis, Honest Tea co-founder Seth Goldman, and Uncharted Play founder (and 30 Under 30 alum) Jessica O. Matthews.
