The new fund is 14% larger than Bain Capital Ventures' previous $1.4 billion vehicle, announced three years ago. From the $1.6 billion pool, the venture division of private equity firm Bain Capital intends to invest in 30 to 40 companies, primarily at the seed through Series B stages.

BCV says it will use the fresh funds to back startups primarily focused on AI, joining other venture investors in directing capital toward the sector. The firm believes artificial general intelligence, which it defines as agents performing many tasks as well as humans can, has already arrived. It expects the next wave of startups not only to harness that power but also to build the infrastructure needed to make it run efficiently.

Partner Kevin Zhang said the main themes for what BCV calls the post-AGI era include infrastructure, healthcare, physical AI and security. He said the firm aims to fund compute infrastructure until intelligence becomes "too cheap to meter," meaning the cost of running AI drops to nearly zero. As one example, he pointed to BCV portfolio company Crusoe, a data center developer reportedly valued at $30 billion and viewed as a near-term IPO candidate. BCV originally led Crusoe's Series A in 2019, when the company focused on crypto mining.

BCV wants to focus on healthcare because it believes the sector may be vastly transformed by AI. Security has recently become a matter of national debate after AI agents went rogue during training, and BCV sees significant potential in that space. Among the firm's notable investments in these areas are Loyal, a longevity startup aimed at pets, and Dream, an AI-powered defender of national infrastructure.

According to Zhang, BCV stands apart from other venture firms because of its affiliation with Bain Capital, which provides deep expertise and financial products across credit, real estate, insurance and private equity. "BCV can support founders not just with equity capital, but with debt facilities, infrastructure partnerships, and real-economy relationships," he said.

Unlike most venture firms, where a single partner champions a deal, BCV's partners often team up in pairs or trios to back a specific investment, Zhang said. "We need to have enough mind space and time to really be thoughtful partners to every team we work with," he said.
