Menlo Ventures $3 billion AI funds target seed through growth rounds

Menlo Ventures has raised $3 billion for two AI-focused funds, its largest fundraise in the firm’s 50-year history. The Menlo Ventures $3 billion AI funds give the firm vehicles for investments from seed through later growth rounds, at a time when partner Matt Murphy says the companies that emerge as leaders are separating faster and remaining private longer.

Menlo announced the capital on June 23 as it marked its 50th anniversary. Menlo Ventures XVII is intended for seed and Series A investments, while Menlo Inflection IV will invest at Series B and later, according to the firm and reporting by Crunchbase News.

The paired structure is the practical change. It gives Menlo the capacity to make an early bet and continue financing selected portfolio companies as their capital needs rise, rather than limiting its role to the first institutional round. For founders, the distinction between seed and Series A remains material, but Menlo is positioning the new funds to cover both those stages and subsequent growth financings.

What will Menlo Ventures’ $3 billion AI funds invest in?

Menlo says the funds will seek investments across AI infrastructure, frontier or foundation models, and AI-native applications for enterprise, healthcare and consumer markets. Those are stated mandates, not a list of transactions or allocations.

Murphy, who has been a Menlo partner since 2015, told Crunchbase News that AI businesses need more capital than earlier generations of software companies and are staying private for longer. He said the larger fund base allows Menlo to invest at company formation and early funding stages, then put more money behind companies that establish themselves as leaders.

That does not amount to a broad mandate to fund every AI category. Murphy said the firm has adopted a high-conviction approach for the right later-stage companies, while warning that many AI sectors are overfunded and subject to substantial speculation. His view is that a high bar is required even as some winners distinguish themselves quickly.

Why is Anthropic central to Menlo’s AI strategy?

Menlo’s record with Anthropic is the clearest backdrop to the new funds. The firm says it made its first Anthropic investment in 2023, led the company’s Series D a year later and has participated in every round since. Menlo describes that relationship as central to the broader AI strategy it is now extending across infrastructure and software.

Murphy also described an evolution in the AI market. In what he called its first phase, developers selected a model and began building. The next phase, in his framing, involves companies that have reached scale with AI and are seeking to optimize their spending and infrastructure choices. The available interview remarks do not specify which businesses will benefit from that shift.

The disclosed picture is therefore straightforward: $3 billion across an early-stage fund and a growth fund, aimed at the AI stack from models and infrastructure to applications. Whether Menlo can translate its Anthropic experience into further investments will depend on the selected companies it chooses to support in a market Murphy himself says has attracted considerable speculation.
