The Idea: CJ MacDonald had already had one successful exit. In 2012, he co-founded Gyft, a digital gift card platform that let you store and send gift cards from your phone. First Data acquired it in 2014. After a couple years in corporate, CJ got the itch again. He noticed something broken: traditional banks treated teenagers like an afterthought - ridiculous fees, confusing products, and zero financial education. Meanwhile, Gen Z was growing up digitally native with no banking option built for them. In 2018, CJ teamed up with Alexey Kalinichenko (ex-Google, ex-Square) to fix it. This was the beginning of Step.

The Execution:

• 2018: CJ and Alexey founded Step with a simple pitch - a fee-free bank account and Visa card for teens that helps them build credit before they turn 18.
• Sep 2020: Step launched publicly with endorsements from TikTok stars Charli D'Amelio and Addison Rae. Hit 500,000 users within two months.
• Dec 2020: Raised $50M Series B led by Coatue, with backing from Stripe and Will Smith's Dreamers VC.
• Apr 2021: Closed $100M Series C led by General Catalyst. Surpassed 1.5 million users. Stephen Curry and Jared Leto joined as investors.
• Oct 2022: Secured $300M in debt funding from TriplePoint Capital. Launched crypto investing for teens. Hit 3 million users.
• Mar 2023: Crossed 4 million accounts. Won Nasdaq's Fintech Trailblazer Contest. Launched stock investing with fractional shares starting at $1.
• Feb 2026: MrBeast's Beast Industries acquired Step, bringing its 7 million users and full fintech stack under the world's biggest creator brand.

The lesson? CJ built for a generation that legacy banks ignored. While traditional institutions saw teens as too small to matter, he saw them as the next generation of customers who'd remember who helped them first. When MrBeast - whose entire brand is built on connecting with young people - needed a fintech partner, Step was the obvious choice. Sometimes the best exit strategy is becoming indispensable to someone with 460 million subscribers.
