You've almost certainly heard of Mark Zuckerberg, Jeff Bezos, and Elon Musk.

But have you heard of Patrick Collison, David Zalik, or Lucy Peng?

As I'm sure you know, the first group of men were startup founders who went on to become tech billionaires. What you may not know is the second group of people have also joined the tech billionaires club.

We're taking a look at some of that club's new members. To compile this list, we pulled from Forbes wealth rankings and the Bloomberg Billionaires index. To narrow it down, we limited it to people who have made the bulk of their wealth in the past three years.

Combined, these nine men and women have a net worth in the trillions of dollars, come from different countries and continents, and have companies in a range of tech industry sectors. Here are nine of the newest tech billionaires:

Frank Wang, CEO of DJI Technology

Age: 37

Net Worth: $3.2 Billion

Company: Chinese drone maker DJI Technology

Position: Founder, CEO

Wang's company, DJI Technology, has been selling drones since before they were cool. Now, though, they're big business. Between 2016 and 2020, the total amount spent on the robotic aircraft will total $100 billion, Goldman Sachs has estimated. DJI's sales accounted for some 70% of the consumer and commercial portions of the drone market last year, according to Goldman Sachs.

Wang started DJI in 2006 out of his dorm room at Hong Kong University of Science and Technology, and his company was one of the first to market a ready-to-fly drone that actually flew. He's been riding the industry's wave ever since and became Asia's youngest tech billionaire in 2017.

Jan Koum, CEO of WhatsApp

Age: 41

Net Worth: $9.7 billion

Company: Messaging app developer WhatsApp

Position: CEO, Cofounder

Koum moved from Ukraine to Mountain View, California, with his mother when he was 16 and taught himself computer technology in high school. He grew up poor, living off food stamps, before landing a job as an engineer at Yahoo. After leaving Yahoo and spending time in South America, he applied for a job at Facebook but was rejected.

Koum and his cofounder Brian Acton then launched WhatsApp. The app started as a service that allowed users to share their status updates with friends but soon morphed into the messaging service it is today.

In 2014, WhatsApp caught the attention of Facebook CEO Mark Zuckerberg. Koum and Zuckerberg talked shop for two years before Facebook offered to buy WhatsApp in 2014 for $22 billion in cash and stock. As Facebook's stock value rose, so did Koum's net worth.
