You don't need decades of experience to launch a company.

In fact, Millennial entrepreneurs are making a huge impact in various industries, including tech, consumer finance, fashion, and retail.

On Monday, Forbes published its fifth annual list of the most influential people under the age of 30, across 20 categories. The honorees were chosen by a star-studded panel of judges, including Jessica Alba and Tory Burch for retail and e-commerce, and Shonda Rhimes and Kelly Osbourne for Hollywood.

Famed investor Chris Sacca was the judge for the venture capital category, where the investor-turned-founder Rami Rahal was one to make the cut. 

Below, in no particular order, are the most notable entrepreneurs from the list:
