Cheng-Wei Hu helped build NotebookLM at Google, then left the company before turning 30 to co-found Wondering with Angelica Kosasih. The startup turns complex subjects into personalized sequences of short lessons, visuals, podcasts, and exercises. Y Combinator lists Wondering in its Summer 2026 batch, with Hu as founder and CEO.
CommonWealth Magazine’s profile begins not with Google or Silicon Valley, but with Hu’s family in Taiwan. He tells the magazine that being born into his family felt like winning the lottery. He did not mean wealth or private-school access. His parents were civil servants, and he attended public schools. What he valued was their willingness to let him explore, as long as he accepted responsibility for his choices.
As a first-year student at National Taiwan University, Hu traveled to Chandigarh, India, as an education volunteer. He recalls walking nearly an hour to teach English in a classroom without running water or electricity. The students’ enthusiasm and progress convinced him that he wanted to help make learning accessible to anyone who wanted it.
That goal turned his career into a chain of prerequisites. Hu studied finance but taught himself computer engineering, earned a master’s degree at Cornell Tech, joined Google, and worked on NotebookLM. According to the profile, he also stopped actively consuming Taiwanese media and most Chinese-language social media while in college. He instead followed English-language publications, newsletters, podcasts, and international founders as he prepared for work in Silicon Valley.
Hu says Silicon Valley further changed how he approaches uncertainty. Founders are pushed to launch before their products feel ready so the market can expose their blind spots. He also learned to ask directly for conversations, relationships, and resources without treating rejection as a reason to stop.
The profile’s through line is not speed alone. Hu describes ambition as a sequence of choices made without waiting for certainty, followed by responsibility for whatever happens next. Wondering is the latest test of that principle, built by someone whose career has been organized around the question of how people learn.
