Meet the millennial and Gen Z founders growing their startups, raising millions in funding, and using social media to turn their side hustles into seven-figure empires

• Insider's series Star, Rising highlights early-stage entrepreneurs who are gaining popularity.
• Insider has profiled founders all over the world who are innovating their respective industries.

The pandemic spurred a new wave of entrepreneurship, prompting people to start their own companies, and that doesn't seem to be slowing down.

The US saw 3.4 million new business applications in 2021, according to the US Census Bureau. That's in addition to the rise in hustle culture, as the gig economy grows and social media paves way for more virtual shops and accessible marketplaces. In particular, many millennials and Gen Zers are disrupting the industries they work in as they find their place in the protean landscape of entrepreneurship.

With so much change, it can often be hard to track the new innovators seeking to redefine the world around them. That's why Insider has started profiling them in its series Star, Rising, which explores how these entrepreneurs built their businesses, who they call mentors, and what advice they would give others looking to follow in their footsteps.

So far, the series has introduced Oladosu Teyibo, who is sourcing African talent for his software company to increase representation in tech, and Sharmadean Reid, who launched a female-centric financial news publication to educate the rising crop of entrepreneurs. Here are the 19 other burgeoning founders in Insider's Star, Rising series.

In 2019, Reid raised nearly £4 million ($5.5 million) in a funding round led by Index Ventures for BeautyStack and has since rebranded and expanded the platform into The Stack World's marketplace. That milestone made her one of 10 Black female entrepreneurs in the UK who's raised venture capital between 2009 and 2019.
