Menlo Ventures raises $3B, largest in 50-year history, to back AI startups across all stages

Menlo's $3 billion raise marks a pivotal moment in how the venture firm allocates capital within AI. The dual-fund structure reflects a fundamental recognition that AI companies operate under different economic pressures than prior software generations—they require sustained, often massive capital injections to maintain hypergrowth and avoid being overtaken by competitors. Murphy's emphasis on moving from Phase 1 (undifferentiated model adoption) to Phase 2 (infrastructure and cost optimization in a multi-model world) suggests that Menlo sees the era of picking a single foundational model as closed; instead, enterprises will need specialized models and the infrastructure to manage them. This view informs the firm's expanded bets on infrastructure companies like Fireworks, Modal, and OpenRouter, alongside vertical-specific models like Chai Discovery and Skild.

Murphy also reveals an internal shift in investment discipline. Despite the abundance of capital flowing into AI, he notes that "many AI categories are overfunded, and there is a huge amount of speculation." Yet Menlo has responded not by pulling back but by doubling down selectively on what it judges to be the clearest winners—a strategy validated by its early, multi-round backing of Anthropic. The firm's willingness to deploy $100 million-plus into companies like Lovable and Suno signals confidence that the winners of this cycle will compound at "unprecedented rates," justifying both the concentration of capital and the higher valuations those companies command. This approach implicitly accepts that most AI startups will not survive the consolidation Murphy predicts.
