Reserved GPU and colo,
sourced, negotiated,
and closed.
We know who has it and who needs it.
We are an independent infrastructure desk. Not a marketplace. We run both sides of the book: sourcing capacity for the companies that need it, placing it for the operators that have it, and doing the work that gets a deal signed. We are paid only when a deal closes, and you will see the fee structure in writing before we introduce you to anyone.
"Think of us like a specialist recruiter for infrastructure. We know who has capacity and who needs it, we make the introduction, and then we do the unglamorous part that actually gets a deal signed: pricing, technical diligence, documents, and the follow-up nobody else chases. We are paid when it closes, and the fee structure is agreed in writing before any introduction. Our incentive is to find you the right deal, not the most expensive one. Provider identity disclosed on briefing."
Capacity on one side. Requirements on the other.
We represent clients sourcing capacity and operators placing it. Below is a live view of both sides of our book. Client requirements are anonymized, and operator identities are disclosed only on a briefing call.
Tell us what GPU capacity or
colo space you need.
We review your requirements same day, canvas our operator network within 24 hours, and deliver a shortlist with real pricing, not rate card, within 48 hours.

Marketplaces show you options.
We close your deal.
Infrastructure marketplace platforms aggregate providers and let you browse catalogs. But browsing options is not the same as having someone negotiate your contract. We source, structure, and close. A catalog lists options and steps back; we work the deal until it is signed.
| Marketplace (you compare & negotiate) | XIRR Advisors | |
|---|---|---|
| Works for | Platform revenue. Charges providers a listing fee, creating divided loyalties. | No platform economics to protect. Paid when your deal closes, not on volume. |
| What you get | Catalog browse and AI chatbot. Self-serve comparison across thousands of providers. | Curated shortlist in 48 hours, plus a human advisor negotiating your deal. |
| Pricing | Rate card or catalog pricing. What the provider lists publicly. | Negotiated pricing. What sophisticated clients actually pay. |
| Negotiation | Self-serve. You handle the MSA, SLA terms, and contract on your own. | Full MSA, SLA terms, expansion rights, exit clauses. We close it. |
| Cost to you | The marketplace charges providers, and its margin sits in the listed price. | Paid on close, structure disclosed up front. Full representation either way. |
Going direct costs you more
than our fee ever will.
Infrastructure providers optimize for their own margins. We optimize for yours.
| Going Direct | Through XIRR Advisors | |
|---|---|---|
| Who represents you | Provider's sales team or marketplace platform — both optimizing for their own interests | A desk that works the deal to close. Not a catalog. |
| Market access | One provider at a time, rate card pricing | Vetted operator network · Market-rate intelligence |
| Speed | 60–90 day RFP cycles | Qualified shortlist in 48 hours |
| Contract terms | Standard MSA, no flexibility | Negotiate SLA, expansion rights, exit clauses |
| Allocation access | Public availability only | Pre-market allocations via deep partner relationships |
| Your risk | You don't know what you don't know | Expert representation on your side |
| Cost to you | Full rate card + internal procurement overhead | Paid on close · Structure disclosed up front |
Nobody pays until it closes.
Here's exactly how it works.
XIRR Advisors operates on the same model as a specialist recruiter or a freight broker. We are paid on successful placement. On most engagements the operator pays at close. On some, where the work sits on the client side, the client does. Either way you see the structure in writing before we make an introduction. We work both sides of the market and we say so up front. It is why we can tell you in a day whether what you want exists at the price you want. Most of what we do is telling people what is not going to work.
This means our interests are aligned with yours. We only get paid if we find you the right deal and you sign. A bad recommendation means no fee and no repeat business.
We go deep on a vetted network rather than listing everyone. We know each operator's real capacity, real pricing and real constraints, so we can represent honestly what each one offers and point you at the right fit.

We canvass our network
We canvass our operator network simultaneously. You get a commercial-ready shortlist with real pricing, not rate card, within 48 hours.
We negotiate and close
We work the deal through MSA negotiation, SLA terms, pricing, and contract close. Paid on close, fee disclosed up front.
You will see the fee before you sign. XIRR Advisors operates like a specialist recruiter, the same model used by freight brokers, mortgage brokers, and insurance advisors worldwide. We run both sides of the book, we are paid on close, the structure is agreed in writing in advance, and our only incentive is getting the right deal signed.
Start Now →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.
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.
Capacity
We source, evaluate, and negotiate colocation capacity across the US and EU markets on behalf of frontier AI labs, AI scaleups, and Fortune 500 enterprises. Whether you need 50kW for a pilot cluster, 5MW for an AI training campus, or 10+ MW for a foundation model build, 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 clients are actually paying, not what's on the rate card.
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.
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.
Capacity
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.

Our Brokerage Services
XIRR Advisors provides GPU capacity brokerage and colocation brokerage for frontier AI labs, AI scaleups, Fortune 500 enterprises, and sovereign AI initiatives across North America and Europe. We source reserved H100, H200, B200, B300, GB200, GB300, and Vera Rubin GPU capacity through deep partnerships with vetted neocloud operators and bare metal providers. Our colocation brokerage covers Tier III data centers across major US and EU markets. We do not sell GPUs, servers or any other hardware: clients reserve GPU compute capacity from operators, or lease colocation space and power for hardware they own. We are paid on successful placement, and the fee structure is disclosed in writing before any introduction. We deliver a qualified shortlist within 48 hours of receiving your requirements and represent you through MSA negotiation and commercial close.
