Andreessen Horowitz has expanded its fifth Growth fund to $8.5 billion, adding $1.75 billion in fresh capital just days after unveiling a separate $1.1 billion fund dedicated to AI hardware and infrastructure — a one-two punch that underscores how much money venture firms are funneling toward the sector's biggest bets.
The Growth fund, which launched in January with $6.75 billion, invests in companies further along than the typical venture-backed startup and counts Anduril, Coinbase, Cursor, Databricks, Figma, OpenAI, SpaceX, Stripe, Waymo and Wiz among its roughly 100 portfolio companies built up over seven years. The expansion was announced in a post co-authored by general partners David George and Raghu Raghuram, who lead the firm's growth and infrastructure investing.
"Companies are reaching the growth stage faster and gobbling up more cash at higher valuations than ever," George wrote, pointing to the pace at which AI-era startups are scaling revenue and headcount well before they would traditionally have sought growth-stage capital.
Second Fund in a Week
The announcement came just three days after a16z unveiled its new "Machine Age Fund," a $1.1 billion vehicle aimed at the physical buildout of AI — chips, memory, networking equipment, data storage, power and robotics. General partners Ben Horowitz, Martin Casado, Raghu Raghuram, David Ulevitch and David George are named on that fund, which is built on the thesis that the binding constraint on AI progress has shifted from model quality to the physical capacity to build and power the machines that run it.
Together, the back-to-back raises extend a run that began in January, when the firm announced roughly $15 billion in new commitments across its fund lineup — its largest single haul to date — bringing total assets under management to more than $90 billion. The Growth practice alone now oversees more than $24 billion across five fund vintages.
The pace mirrors a broader surge in venture capital this year. Global startup investment hit a record $297 billion in the first quarter alone, more than double the prior quarter's total, as AI-focused rounds have grown larger and closed faster. For a16z, expanding two funds within the same week signals a bet that the capital intensity of AI — from model training to the data centers and chips underneath it — still has room to grow before it levels off.
