Wonjun Jeong is the co-founder and CEO of Supermove, a San Francisco software company that replaces the paper contracts and typewriters still common in the moving industry with a single cloud platform for sales, dispatch, scheduling, signatures, payments, and payroll. A UC Berkeley computer science graduate who wrote code at Facebook and Pinterest, he started Supermove in 2019 after moving 21 times and watching movers scratch his credit card number into a paper form with a fingernail. The company raised an $18 million Series A led by Andreessen Horowitz in 2022 and works with more than 100 moving and storage firms.
Pinterest is a visual discovery and inspiration platform where people find and save ideas for projects and interests, from recipes and home decor to fashion and travel. Founded in 2010 and headquartered in San Francisco, it lets users organize images called Pins into themed collections called boards, and increasingly acts as a shopping-and-discovery engine powered by visual search and AI. Publicly traded on the NYSE, Pinterest reached roughly 631 million monthly active users and $4.2 billion in 2025 revenue, earning nearly all of that from advertising.

Connie Chan is a venture capitalist and technology writer who spent 12 years at Andreessen Horowitz (a16z), becoming the firm's first-ever internally promoted General Partner in 2018. Known as 'Silicon Valley's China Whisperer,' she made her mark by translating Asian tech trends - super apps, social commerce, livestream shopping - into investment theses before Western founders even knew the terms. Her 2015 WeChat essay won the New York Times Sidney Award and predicted the app-consolidation wave that would reshape mobile over the following decade. She backed Pinterest early, championed Lime before scooters were cool, and holds board seats at Whatnot, KoBold Metals, and Cider. In January 2024, after 12 years at a16z, she stepped back from GP duties to pursue a new Asia-focused venture.
