Portfolio

What a Layer H company looks like.

We are early and deliberately concentrated. Below are companies that define each layer we back. They are references for the kind of business that gets stronger as models improve, not current holdings.

Representative of the categories we back. Not current Layer H holdings.

Read how we invest
  • 01Vertical Intelligence

    Harvey

    End-to-end legal AI for law firms and corporate legal teams.

    Owns the workflow, the data, and the trust relationship a better model only deepens.

    Backed by the OpenAI Startup Fund and Sequoia; used across global law firms.

  • 02Physical AI

    Foxglove

    Data infrastructure and observability for robotics teams.

    The layer every autonomous program uses to record, replay and understand what its machines did, agnostic to which machine wins.

    Backed by Eclipse Ventures and Amplify Partners; used by robotics teams from early startups to NVIDIA and Amazon.

  • 03Agentic Commerce

    Skyfire

    Identity and payments for AI agents.

    Sits at the authorization and settlement layer every agent transaction must pass through.

    Backed by a16z CSX and Coinbase Ventures; a Visa Intelligent Commerce partner.

The bar

Three tests before we invest.

  1. Owns something the model cannot recreate

    Proprietary data, a system of record, a regulatory license, or the distribution. Not a prompt and a UI.

  2. Sits in one of the three layers

    Vertical Intelligence, Physical AI, or Agentic Commerce. If it does not, it is not for us.

  3. Gets stronger when the next model ships

    The single question. If a more capable model erases it, we pass, however good the traction looks.
