The firm said AI’s expansion into reasoning, coding and workplace automation is increasing demand across the broader physical supply chain, including power, cooling and data transmission. a16z also expanded its fifth growth fund from $6.75 billion to $8.5 billion after raising an additional $1.75 billion. The firm plans to strengthen its Growth Platform with recruiting, global networks, media, sales and marketing, and pricing support. Its Seoul office, opened in June, will serve as a hub for helping portfolio companies enter South Korea and wider Asian markets, while a16z identifies opportunities with Korean companies.
