While many top-tier venture firms keep raising massively larger funds, Greylock Ventures, one of the oldest and most prestigious venture firms in Silicon Valley, is intentionally resisting the trend of ballooning fund sizes.

On Tuesday, the 61-year-old firm announced that it had raised a $1.5 billion 18th fund. The number is 50% higher than its previous $1 billion vehicle from 2023 and roughly matches the capital the firm raised across seed and flagship funds during the pandemic. Still, Greylock partner Saam Motamedi told TechCrunch that Greylock could have easily raised a “multiple” of that figure, suggesting the partnership decided restraint was the better path at a time when fund sizes across the industry keep climbing.

“Our mission is to be the most important partner to the most important entrepreneurs,” Motamedi said. The firm prides itself on introducing its portfolio companies to top engineers and potential customers, as it did for Baseten, an AI infrastructure startup that is now valued at $13 billion, after first investing in its Series A in 2022. But Motamedi said Greylock can offer that level of support only by keeping the number of companies it backs small.

The firm’s 10 partners make only one or two new investments each annually, a pace Motamedi said will result in roughly 25 portfolio companies from this fund.
