Digital Infrastructure Advisory

The infrastructure
intelligence layer
for AI-era compute.

XIRR Advisors sources and structures US colocation capacity and reserved GPU capacity across North America and Europe — for enterprises, hyperscalers, and AI-native companies who need an edge in a constrained market.

"The companies winning the AI infrastructure race aren't the ones with the biggest budgets — they're the ones with better market intelligence and faster procurement cycles. That's what we provide."

Who We Are

Boutique advisory for the
compute-constrained.

XIRR Advisors operates at the intersection of infrastructure markets, procurement strategy, and financial discipline. We exist because sourcing GPU and colocation capacity at scale has become a high-stakes market problem — not just an engineering one.

Our name reflects our orientation: XIRR — the financial metric that captures the true return on capital deployed over irregular time intervals. We optimize that number for our clients.

Partner-alignedWe work with a curated network of preferred GPU and colocation partners. Our relationships are built on trust, performance, and repeat business — not one-off transactions.
Market-connectedDeep partnerships with top GPU providers and Tier III colo operators across North America and Europe.
Operationally experiencedHands-on experience in HPC procurement and colocation procurement — we've been on both sides of these contracts.
Speed-firstGPU windows close in days. Our process is engineered to compress sourcing cycles from months to weeks.
Our Practices

Two focused practices.
One clear objective.

We don't try to do everything. We go deep on the two most constrained, highest-stakes infrastructure categories in the AI economy right now.

01

We source, evaluate, and negotiate colocation capacity across the US market on behalf of enterprises and AI-native companies. Whether you need 50kW for a pilot cluster or 5MW for a full AI training campus, we run simultaneous outreach across our network of qualified operators and deliver a commercial-ready shortlist in days — not a 90-day RFP cycle.

We know which facilities have real GPU-density power available, which operators are flexible on MSA terms, and what rates sophisticated buyers are actually paying — not what's on the rate card.

Scope: Colocation engagements carry a minimum 5-year commitment.

Facility Sourcing & Shortlisting

Simultaneous canvass of our qualified US colo operator network, matched against your power, density, redundancy, latency, and compliance requirements. Qualified shortlist in days.

Power & Capacity Analysis

Critical power availability, PUE benchmarking, cooling infrastructure assessment, and stranded capacity identification. We model the true all-in cost per kW — including cross-connects, remote hands, and overhead — so you're not surprised post-contract.

MSA & Contract Negotiation

Representation through Master Service Agreement negotiation and commercial close. Colocation engagements carry a minimum 5-year commitment. We know what rates are achievable, which SLA terms are movable, and how to structure expansion rights, exit provisions, and escalation caps that protect your long-term position.

MSA / LOISLA TermsRate NegotiationExpansion RightsExit Provisions

We source and structure reserved GPU capacity commitments across North America and Europe — leveraging deep partnerships with top GPU providers to secure allocations that match your training and inference workload profiles, on terms that hold.

Reserved capacity is where pricing complexity, allocation risk, and contract structure have the greatest financial impact. Our exclusive focus on reserved — not spot, not on-demand — means we go deep on the economics and terms that determine your actual cost of compute.

Scope: Our GPU practice is reserved-capacity only. Minimum commitment is 6 months. Spot and on-demand optimization is a different discipline — and not ours.

Reserved Capacity Sourcing

Through deep partnerships with top GPU providers across North America and Europe, we source reserved commitments across the full NVIDIA architecture stack — from A100 through Vera Rubin. We identify and secure allocations before they reach the open market.

Contract Structuring & Close

Term sheet review, SLA negotiation, and commercial close on reserved GPU contracts. We structure commitments to preserve flexibility — burst rights, early termination windows, capacity upgrade paths — while locking in the rates and guarantees you need to plan confidently.
