Welcome to the 247th episode of the Inc. Uncensored podcast, hosted by Inc.'s executive director of editorial, Jon Fine.

First, senior writer Christine Lagorio-Chafkin breaks down the latest twist in the entrepreneurial journey of Bumble founder Whitney Wolfe Herd. She's taking over as CEO of MagicLab, which owns Bumble and three other dating apps: Badoo, Chappy, and Lumen. Herd, who is known for her women's empowerment efforts, has her work cut out for her--Badoo has allegedly been struggling with a toxic, sexist workplace culture.

Next, staff reporter Guadalupe Gonzalez delves into the food delivery wars between Grubhub, DoorDash, Postmates, Uber Eats, and countless other entrants. Grubhub is the only profitable company of the bunch, and its competitors have large cash reserves thanks to a huge recent influx of VC funding. Eventually, though, that bubble may have to burst.

Finally, I discuss the rise of TikTok as a major social media platform in the U.S.--and why Silicon Valley's giants are having so much trouble defeating it. TikTok is owned by Bytedance, a Chinese tech giant that specializes in artificial intelligence and machine learning. Because of the company's vast resources, the traditional crush-the-upstart playbook--copy, acquire, and discredit--isn't working for Facebook, Google, and the rest.
