Andreessen Horowitz Raises $1.1B for AI’s Physical Infrastructure, From Chips to Robotics

The first hardware-specific vehicle in the firm’s portfolio turns an existing AI investment program into a dedicated mandate spanning compute, power, facilities and physical machines.

Andreessen Horowitz has raised one-point-one billion dollars for the physical infrastructure that AI needs to grow, creating its first hardware-specific investment vehicle, called the Machine Age Fund. The mandate runs from chips and memory to data centers, power equipment, edge devices, appliances, and robots. The underlying argument is simple: AI capacity is not limited to processors. Large clusters also need networking to move data between chips, storage for huge datasets, cooling, transformers, and facilities designed for dense computing. The firm’s general partners David George and Erik Torenberg describe this as a physical rebuilding of computing infrastructure for AI. The fund is organized around three layers. First, compute and data movement: chips, memory, storage, and networking. Second, facility systems, including data centers and power infrastructure. Third, physical AI products, such as edge hardware, smart-home appliances, and robots. This builds on more than six infrastructure investments already made by the firm, including Heron Power, data-center builder Volta Infrastructure Holdings, and chipmaker Unconventional. Heron makes solid-state data-center transformers that reduce electricity to a usable distribution voltage. Alongside capital, the firm says it will provide recruiting, marketing, and go-to-market support. Its partners argue that hardware suppliers’ usual twenty-to-thirty-percent annual growth may fall short of demand they estimate requires triple-digit growth. The key constraint is whether the broader hardware supply chain can scale as quickly as AI deployment requires.

Story brief

3 key points

Andreessen Horowitz has created a $1.1 billion fund for the hardware and facilities needed to expand AI, extending beyond processors into memory, networking, data centers, power systems, edge devices, appliances, and robots. The strategy reflects a capacity bottleneck: AI deployment depends on transformers, cooling, storage, and dense-compute facilities as much as chips. The firm says it has already backed more than...

  1. 01

    Heron Power, Volta Infrastructure Holdings, and Unconventional are among a16z’s named infrastructure investments.

  2. 02

    The fund spans three layers: compute and data movement, facility systems, and physical AI products.

  3. 03

    a16z says hardware suppliers’ typical 20%–30% annual growth may not meet AI-driven demand, which it estimates requires triple-digit growth.

Andreessen Horowitz has raised a $1.1 billion Machine Age Fund for the physical systems behind AI. Its first vehicle specifically focused on hardware infrastructure places chips, data centers, power equipment and robotics inside one investment mandate.

The fund is built around a practical constraint on AI capacity: compute requires more than processors. AI clusters need networking to connect processors, storage to move large datasets, and cooling, power infrastructure and data-center designs that can support dense computing environments. General Partners David George and Erik Torenberg characterize that work as a physical rebuilding of computing infrastructure for AI.

From the data center to devices

The mandate extends from central infrastructure to hardware closer to where AI is used. It covers chips, memory, storage, networking, data centers and power systems, alongside edge AI hardware, smart-home appliances and robots. That breadth puts facility equipment and physical AI products under the same fund.

Three investment layers

  • Compute and data movement: chips, memory, storage and networking equipment.
  • Facility systems: data centers and power infrastructure.
  • Physical AI products: edge hardware, smart-home appliances and robots.

An investment thesis already taking shape

The firm’s named infrastructure portfolio companies include Heron Power, data-center builder Volta Infrastructure Holdings and chipmaker Unconventional. Heron makes data-center transformers, which reduce electricity to a voltage suitable for distribution. The company says its systems use power-management chips in a solid-state design rather than the metal coil used in standard transformers.

Capital is only one part of the buildout

Andreessen Horowitz plans to pair its capital with go-to-market, recruiting and marketing support for hardware portfolio companies. Its partners have argued that hardware suppliers are accustomed to 20% to 30% annual growth, while saying triple-digit growth is needed to catch up with demand. That assessment is the firm’s own market view, but it explains why the mandate reaches beyond chip design into the suppliers around it.

The move comes as venture firms raise more AI-focused capital. Kleiner Perkins raised $3.5 billion across two funds in March, including one for early-stage AI startups. Andreessen Horowitz’s distinction is its dedicated focus on the equipment and facilities that support AI systems.
