You don't have to be in your fifties to make a difference. In fact, some of the most prolific founders today -- like inDinero's Jessica Mah -- have demonstrated wisdom beyond their years.
This week, LinkedIn revealed its first-ever list of "Next Wave" figures under the age of 35. The compilation of names includes founders, chief executives, and other professionals that the networking website deems to be game-changers in their respective industries.
To create the list, LinkedIn looked at its own data, such as a given candidate's profile views and engagement rates on the website. It also parsed hot news topics, and polled "LinkedIn Influencers" for their recommendations.
Significantly, as many as 80 percent of 150 individuals on the list did not attend an Ivy League school. Only 15 percent have an MBA degree.
Here's a quick look at some of the most notable names in entrepreneurship to make the list:
1. Parker Conrad, CEO and co-founder, Zenefits
Conrad, 35, helms a payroll company that's presently valued at $4.5 billion, with around 10,000 clients. Zenefits' free software is changing the way that businesses manage HR.
2. Louis Beryl, CEO and co-founder, Earnest
Earnest, a lending firm which offers to refinance student loans, has raised as much as $32 million in venture capital funding to date. Beryl, 34, started the company when he was initially unable to secure a student loan to attend Harvard Business School.
3. Jessica Mah, CEO and co-founder, inDinero
Mah's inDinero -- an accounting software firm that targets small businesses -- nearly went bankrupt just one year in. Here's how Mah, who started the company when she was 19, was able to turn things around, ultimately landing the cover of Inc.'s September 2015 issue.
