Amber Atherton sold her startup to Discord and now backs seed-stage startups. Marissa Brooks jumped from being an executive assistant to director of development at CBS Studios in just a few years.  You might not have heard of the trio before now, but each is a rising star in their industry.  In recent months, Business Insider has highlighted those rising up the ranks and shaping change on Wall Street, in Silicon Valley, and in Hollywood. We’ve taken a look at Madison Avenue, the healthcare industry, and the real-estate business, too.  I always enjoy these profiles. I’ve long felt that companies don’t do things, people do. That innovative new project didn’t just happen. Someone made it happen. I’m fascinated to learn about the people behind the latest product launch, entry into a new market, or fresh initiative. It’s also true that often these younger executives are at the forefront of change. They aren’t just managing transformation from a distance, but they’re often the ones driving it or riding its wave. In that sense, these profiles can also offer a window into where an industry is headed. In 2024, Business Insider will continue to report on the people behind the business stories you’re most interested in, with a sharp focus on what’s new and where the world is headed.  I know a lot of you reading this are similarly pushing the world forward, by setting big goals, making plans to achieve them, and executing every day. I hope you’re able to achieve your ambitions, whatever they may be, in the year ahead. Thank you for reading, and Happy New Year!

The once-weekly injection was developed to treat type 2 diabetes, with a side effect of melting pounds off at a stunning rate.  In 2023, people began asking for the drug by name and speculating that celebrities were utilizing the shot, or similar drugs, like Wegovy or Mounjaro. Business Insider spoke with doctors and patients about the year spent obsessing over weight-loss drugs — and what the future could hold. Inside the rise of weight-loss drugs.

Nick Little for BI Searching for companionship on TikTok Cindi White, a 65-year-old retiree, was immediately enthralled when she first stumbled upon TikTok’s Live Matches in 2021. The popular battles have creators competing for likes and virtual gifts from their fans, who spend real money to send the virtual tokens.  Over the course of the next year and a half, White said she devoted as much as 50 hours a week to livestreams — and that she had spent more than $25,000 by the end of 2023.

According to a December 7 report from Bank of America, the 16 states that make up the region accounted for 39% of the entire US population as of 2022.  Newcomers to the area are entering a hot job market. Per BofA, the South has the highest job openings rate and the lowest unemployment rate of any region. It’s also seen the largest uptick in credit card spending. If these trends continue, economic and societal power could shift from coastal cities to southern hubs like Houston, Dallas, Nashville, and Miami. A new era of the American economy.
