From Side Hustle to Success: Three Women Share Their Journey to Building Multimillion-Dollar Businesses

Discover the inspiring stories and advice of three women who turned their side hustles into thriving multimillion-dollar businesses.

In today’s economy, where financial stability is uncertain, side hustles have become a lifeline for many Gen Zers and millennials. A recent survey from LendingTree revealed that over half of these young adults have a side hustle, with 80% citing the need for extra cash as the driving force behind their entrepreneurial endeavors. From driving for rideshare services to teaching courses online, there is a wide range of opportunities for those looking to diversify their income streams or pursue full-time entrepreneurship.

While some side hustlers achieve great success and surpass their full-time job salaries, others may start with modest returns but possess an entrepreneurial spirit that propels them to commit fully. With the right strategy and mindset, these businesses can also become highly profitable, even reaching six- or seven-figure monthly revenues.

In this article, we delve into the stories of three remarkable women who transformed their side hustles into thriving multimillion-dollar businesses. Katherine Watercutter, founder and CEO of activewear brand Gold Hinge; Julie Berninger, co-founder of e-printables curriculum Gold City Ventures; and Danielle Cohen-Shohet, founder and CEO of booking and payments platform GlossGenius, share their journeys and offer valuable advice for business success.

Julie Berninger: Gold City Ventures

She opened an Etsy shop focused on the bachelorette party niche and eventually co-founded Gold City Ventures, an online course business that teaches entrepreneurs how to find success on the platform. Berninger left her 9-5 job when her side ventures generated enough income to replace her salary.

Danielle Cohen-Shohet: GlossGenius

Danielle Cohen-Shohet’s entrepreneurial journey began in college when she did freelance makeup from her dorm room. Alongside her twin sister, she also ventured into the world of digital receipts and payments.

Today, GlossGenius is valued at over $510 million.

Cohen-Shohet’s advice: “Be fearless, surround yourself with like-minded people, and never take no for an answer. Having a strong support system and thought partner can be invaluable in building a successful business.”
