Talking AI Tech Applications, Founder Mindset, and the Scale of Entrepreneurship | A Conversation with Xiaoyu Wang of Castbox

In 2016, Castbox launched and entered the overseas mobile podcast market, filling a gap and reaching 30 million registered users at its peak — topping the charts among third-party podcast apps.

After 2018, Spotify poured heavy investment into podcasts, and Castbox faced commercialization challenges and market pressure. Founder Xiaoyu Wang led her team through a difficult exploration, ultimately achieving a breakthrough by pivoting to a matrix strategy and developing a range of entertainment-related products. Today, this former Google engineer — a Peking University psychology graduate with years of development experience — is following her entrepreneurial path, leading a company with over 50 products and more than 50 million monthly active users worldwide.

As a surfer of the internet entrepreneurship era, Wang and her team actively track AI technology developments and have launched several AI-native products. She has her own unique perspective on how to build a great AI product in an internet environment. In this episode, we invited Monica, Investment Vice President at ZhenFund, and Xiaoyu Wang, Founder and CEO of Castbox, to discuss the unconventional thinking behind her entrepreneurial journey — her mindset as a founder and her philosophy on company structure — as well as the changes and challenges encountered while actively integrating AI into the business.
