Private AI Infrastructure · Immerline Infrastructure Inc.

AI is the product.
The infrastructure is the business.

Red Team Investments has run modular data centers since 2021 and put Xydo into operation in January 2026 — sovereign AI for organizations that cannot hand their data to someone else's cloud. The platform is built and in market. What scaling it takes is compute: GPUs bought, financed, powered and housed. CapStack Ventures Fund LLC is raising the capital to acquire and finance that infrastructure, through a joint venture between Red Team Investments and Immerline Infrastructure Inc.

Modeled total Class A MOIC
Modeled, not guaranteed
Pre-exit capital recovery depends on a full free-cash-flow sweep, subject to operating reserves, and server financing on modeled 60-month amortizing terms at 12%, with principal payments commencing in the third period. These terms require confirmation in the JV Operating Agreement and lender agreements.

Modeled figures reflect the Mid case of the RT Fund 2 JV CapStack Model v4.1, August 2026. They are forward-looking and not guaranteed; actual results will differ. Complete terms, assumptions and risk factors are set out in the offering documents.

Preferred dividend

The 12% cumulative preferred dividend accrues on invested capital from deployment and is payable quarterly when declared by the Immerline Board from legally available funds. Otherwise, it accrues until paid. The model assumes no distributions during the first seven months following initial deployment. Preferred dividend accrual stops when original capital is recovered. Payments are not guaranteed.

Modeled return

The modeled 6.07× multiple includes return of original capital, pre-exit distributions and exit proceeds. Returns are net of Co-Sponsor Class B equity but before the 1% Administrative Services Fee, Fund expenses, entity-level taxes and investor taxes. Figures reflect the modeled Mid case, not guaranteed results.

How distributions flow

A modeled distribution waterfall.

1
Return of capital

Class A receives priority return of original capital.

2
Accrued preferred

Class A receives priority payment of its accrued preferred dividend.

3
Post-recovery distributions

After capital and accrued preferred are recovered, the effective JV share flowing to Immerline is split between Class A and Class B under the disclosed waterfall.

4
Potential exit

Exit proceeds are distributed under the governing terms. Exit timing and occurrence are not guaranteed.

Qualification. JV debt service and operating reserves precede investor distributions. Preferred dividends require Board declaration and legally available funds. The model assumes no distributions during the first seven months. Preferred accrual stops at original-capital recovery. The diagram above is a model of waterfall order, not a guarantee of payment or of investor priority over lenders.
Return of capital

Capital modeled back before the exit — not at it.

Initial deployment
Deployment
Capital deploys into GPU hardware and the strategic equity position.
Modeled prior to month 36
Capital returned
All original capital modeled back to Class A from operations.
Following capital recovery
Preferred cleared
The 12% cumulative preferred modeled as fully paid. It stops accruing at capital recovery.
Modeled, and conditional. Pre-exit capital recovery is not guaranteed. It requires the joint venture to distribute its full free cash flow, subject to operating reserves, as its distribution policy — of which an effective 80% flows to the SPV during the recovery phase — and server debt on a 60-month amortizing schedule at 12% with principal commencing in the third period. Both must be confirmed in the RT Fund 2 Operating Agreement and the lender agreements before capital is deployed. Modeled timing reflects the Mid case of the model of record and will differ in practice.
The opportunity

Four layers of the AI stack, one company — in an industry where most competitors own exactly one.

01 — Vertically integrated


Eight years building integration and consulting, an orchestration platform, private cloud compute, and the data centers to put it in.

02 — Hardware plus equity


The JV combines GPU operations with an RTI equity position. Both depend on the same compute business and do not diversify one another. A downturn in compute demand could reduce operating cash flow and the value of the equity position together.

03 — Sponsors paid last


After JV debt service and operating reserves, Class A has priority over Class B distributions until original capital and the full accrued preferred dividend are recovered. Class B is management equity and receives no distributions until that recovery is complete.

QSBS targeted, not confirmed. Immerline Infrastructure Inc. is structured to pursue treatment under IRC §1202. Eligibility depends on entity-level requirements at Immerline and RT Fund 2, the Fund's holding period at disposition, and each investor's circumstances. Whether and how any exclusion passes through to Fund investors requires tax counsel opinion and CPA review. Under the modeled exit, a reduced exclusion would apply if the investment qualifies; full exclusion would require the complete statutory holding period. QSBS is a potential additional benefit, not a confirmed tax outcome. Investors should consult their own tax advisors.

Hardware lien protection

Immerline Infrastructure Inc. will hold a UCC-1 lien on the original GPU hardware upon perfection, a condition to deployment. On debt-financed expansion hardware, Immerline's claim is subordinate to the debt provider and covers only value above the outstanding debt. That remaining value may be limited or eliminated in a downside scenario.

Before you register

Key risks and conditions

Expansion financing

The growth model depends on additional GPU capacity financed beyond the initial hardware allocation. It contemplates approximately $92 million of debt principal. No lender is committed at this time, and debt service takes priority over investor distributions. Expansion GPU purchases or leases cannot close until acceptable financing is secured and committed, with unanimous approval of the RT Fund 2 Board of Managers. Modeled returns depend on these financing assumptions.

Conditions remain open

Independent valuation, QSBS review, additional customer-contract conversion, lien perfection and required JV Operating Agreement provisions remain subject to confirmation as described in the Individual Investment Disclosure.

Illiquidity and loss

No public market exists for Fund, SPV or JV interests. Investors must be prepared for an illiquid investment and the possible loss of their entire investment.
