Bain Capital Ventures raises $1.6B fund to bet big on AI

Bain Capital Ventures (BCV), the venture arm of private equity firm Bain Capital, has raised a new $1.6 billion fund — 14% larger than the $1.4 billion fund it announced three years ago. Like many other venture investors, BCV says it will deploy the fresh capital primarily into startups building around AI.

The firm believes artificial general intelligence — which it defines as agents performing many tasks as well as humans can — has already arrived, and that the next wave of startups won’t just harness that capability but also build the infrastructure needed to run it efficiently. Partner Kevin Zhang said the most relevant themes in what the firm calls “the post-AGI era” are infrastructure, healthcare, physical AI, and security. BCV aims to keep funding compute infrastructure until intelligence becomes what the industry calls too cheap to meter — the point when the cost of running AI drops to nearly zero, Zhang said, pointing to portfolio company Crusoe, a data center developer reportedly valued at $30 billion and viewed as a near-term IPO candidate. BCV first led Crusoe’s Series A back in 2019, when the company was focused on crypto mining.

On healthcare, the firm believes the sector may be vastly transformed by AI. In security — a field Zhang said has become a matter of national debate after AI agents went rogue during training — BCV sees plenty of potential to bet on; its portfolio there includes Loyal, a longevity startup for pets, and Dream, an AI-powered defender of national infrastructure.

Zhang said BCV’s affiliation with Bain Capital sets it apart from other venture firms, giving it access to expertise and financial products spanning 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. From the new fund — the firm’s 11th — BCV plans to invest in 30 to 40 companies, primarily at the seed through Series B stages. Unlike most VC firms, where a single partner champions a deal, BCV partners often team up in pairs or trios to back a specific investment, a structure Zhang said gives the firm enough capacity to be thoughtful partners to every team it works with.

Why it matters

BCV’s bet that AGI has effectively arrived — and that the next opportunity lies in the infrastructure and vertical applications built on top of it — signals where a chunk of the next $1.6 billion in venture capital will flow, from compute to healthcare to security.
