Castra Capital

Compute / Capital advisory & special situations

Compute is physical.
Capital must
understand it.

We connect compute assets, capital, and operators—helping projects become financeable and preparing to keep productive infrastructure running when capital structures break.

A claim on a GPU is only useful if the GPU can stay powered, connected, and earning.

Understand the asset. Structure the financing. Preserve the ability to operate.

01 / The approach

One operating perspective.
Two distinct mandates.

AI infrastructure combines fast-moving hardware with long-lived financing and physical dependencies. Our approach starts with what the asset can earn, who controls it, and what survives a change of ownership.

Capital advisory

Make the project
financeable.

Help lenders and asset owners evaluate compute economics, assemble the financing and operating counterparties, and structure a claim that can be understood and monitored.

  • Asset and cash-flow diligence
  • Financing structure and counterparty coordination
  • Collateral, site, and operating-readiness assessment

Financing providers commit capital directly. Castra’s advisory role does not require warehousing loans, guaranteeing repayment, or providing a committed takeout.

Castra Compute I / Special situations

Invest when the
basis makes sense.

We are raising separately committed capital to pursue discounted compute claims, recapitalizations, and operating assets when financing stress creates an attractive entry point.

  • Discounted secured claims and rescue financing
  • Restructuring and access to the operating asset
  • Utilization, recontracting, and disciplined exits

Fund investments are separately underwritten. An advisory engagement creates no obligation for the fund to finance a project or purchase its debt.

02 / Underwrite the whole asset

The chips are
only the beginning.

Hardware value, site access, power, and customer revenue belong in the same underwriting conversation. Explore the four dependencies.

Asset identity & recoverability

Know what you own.
Know what it can earn.

Generation, configuration, utilization, and support determine the economics. A serial-level asset registry and a clear security interest connect the financial claim to the physical fleet.

Evaluate
Fleet configuration, useful life, rental economics, resale basis, and vendor support.
Prepare
Asset identification, credentials, maintenance records, and a path to possession.

03 / Across the financing cycle

Prepare early.
Deploy selectively.

Good preparation improves the financing today and the choices available tomorrow. Investment entry depends on price, enforceable rights, and a credible operating path.

  1. 01

    Structure

    Understand the fleet economics. Align the financing with contracts and physical dependencies.

  2. 02

    Monitor

    Follow utilization, contract roll-offs, collateral value, and the capacity to service debt.

  3. 03

    Recapitalize

    Evaluate discounted purchases, rescue capital, and restructuring when the entry terms justify it.

  4. 04

    Operate

    Secure the site and an operating partner. Keep the fleet productive, recontract, and realize value.

Distress is a potential entry point—not a requirement to invest. Capital remains subject to independent underwriting and investment discipline.

04 / Connect with Castra

Assets. Capital.
Operating capability.
