Venture investor 1 said Tuesday that it has raised $3 billion in new capital — the largest new raise in the firm’s 50-year history — to back AI-focused startups across enterprise, healthcare and consumer sectors.

“We made our first investment in Anthropic in 2023, when the company was pre-product, pre-revenue. By then, ChatGPT was a household name, and many believed the LLM race was already decided. We saw it differently,” the firm wrote in published Tuesday. “In and his founding team — arguably the most accomplished researchers in the field — we saw the rare mix of technical depth and clarity of purpose that defines a category leader. We were convinced there was room for another independent foundation model company, that Anthropic was the team to build it, and that an investment in Anthropic could anchor our broader AI strategy.”
The firm went on to lead Anthropic’s the following year.
“That early relationship gave us a rare vantage point on the model layer and on the infrastructure, workflows, and application opportunities forming around it,” the firm said this week.
Two new funds
The firm’s new capital is across two funds: , earmarked for seed and Series A startups, and , a growth fund for Series B and later startups that are “already pulling away from the pack and on their way to becoming the breakout names of the AI era.”
Along with Anthropic, other notable Menlo Ventures investments over the years include , , , and . Anthropic, which has filed plans for a 2026 IPO, would be the largest exit to date for one of its portfolio companies by far, with an expected IPO target of $1 trillion or more.
