Market data and research subscriptions
Entitlement inventories, exchange declarations, user-level allocation and the contract terms that govern them.
Market data →Built for financial services
Nexus One connects every vendor contract to the services bought under it, the applications those services feed, and the people who actually use them — so duplicate entitlements, unmanaged renewals and out-of-profile allocations become visible before the invoice arrives.
The gap
Your purchase workflow governs what gets bought. Almost nothing governs what happens next — and none of the following trips an approval step.
Licences stay allocated to people who have moved desk, changed role, or left. They renew because no one is asked to confirm they are still needed.
Regions and business units sign separately with entities that share a parent. Without resolved vendor identity, the overlap is invisible.
Geographic restrictions, derived-data rights, tiered pricing and notice periods sit in signed documents nobody reads until an audit.
Month-on-month changes get investigated by hand, weeks after the fact, from spreadsheets assembled out of several systems.
What Nexus One does
Inventory tools hold vendors and contracts. Contract tools read clauses. Software tools map applications to users. Nexus One holds the whole chain in a single traversable graph, which is what makes the questions above answerable.
Every record is a node with real edges between them. Start at a vendor and walk down to the individuals consuming it, or start at a person and walk back up to the agreement that permits it.
Master agreements, schedules, order forms and side letters are classified, grouped into families and parsed into structured terms under the W3C ODRL schema. Each extracted field keeps a link to the sentence it came from and a confidence score.
Deterministic checks run without a model call — expiry dates, duplicate assignments, required fields. Model-assisted checks handle the ones needing interpretation. Rules are saved, scheduled, versioned and re-run.
Anything below the confidence threshold enters a review queue rather than flowing downstream. Vendor matches, extracted terms and rule findings all carry an audit trail of who accepted what.
When a vendor appears in adverse media, the alert arrives attached to your exposure — the contracts it governs, the services and applications that depend on it, the people consuming them, and how much of the estate sits behind that one parent group. The monitoring is commodity. The linkage is not.
Clause extraction alone is close to commodity in 2026. The value here is what the extracted term is connected to. All four capabilities →
Where it applies
Agreements that span regions and legal entities, rights that are conditional rather than absolute, overlapping multi-year schedules, and vendor identities that fragment across a dozen names. Whichever category the spend sits in, that is the hard part.
Entitlement inventories, exchange declarations, user-level allocation and the contract terms that govern them.
Market data →The same graph applied to application licensing, renewals and departmental allocation — where the contract terms are simpler but the sprawl is wider.
Technology spend →Telecoms, professional services and wider indirect categories use the same data model. We would rather prove two domains properly than list six.
Deployment
Nexus One deploys into your own Azure or AWS environment. Reasoning runs against a local model to limit exposure, updates are pulled by you rather than pushed to you, and your operational data stays inside the region you nominate.

A short note is enough to start — the rough scale and shape of the spend, the systems you use today, and what prompted you to look now. We will come back with a straight answer about whether Nexus One fits.
Platform
Nexus One ingests contracts, spend records, service inventories and user data, resolves them into one connected model, and runs a repeatable set of checks over it. Every finding traces back to the record — and the clause — it came from.
Layer 1 — identity
Nothing downstream is trustworthy while the same supplier exists five times under five spellings. Vendor resolution is the first thing Nexus One does and the thing everything else depends on.
Raw vendor strings are normalised, "known as" names are mapped, and near-duplicates are surfaced for confirmation rather than merged silently.
Legal entities are rolled up to their parent, so spend concentrated across four subsidiaries reads as one relationship at negotiation time.
Optional PermID enrichment links internal records to an external identifier, with low-confidence matches routed to review and stale-data controls on lookups.
Layer 2 — contracts
Contract families are assembled automatically: master agreements with their schedules, order forms and side letters grouped under one governing document, with overlapping multi-year terms tracked side by side rather than overwriting each other.
Layer 3 — consumption
Contracts connect down to the services bought under them, the applications those services feed, and the individuals and cost centres consuming them. That chain is what turns an inventory into an answer.
Category and data-content classification, delivery mechanism, latency, pricing and currency, geographic restrictions, and the governance and licensing fields attached to each line.
Which applications consume which services, and which applications depend on each other — so the impact of dropping or renegotiating a service is visible before the decision.
Service lines mapped to people, teams, divisions and cost codes, giving allocation and concentration rather than a single firm-wide total.
Select, expand, focus and filter across vendors, contracts, services, applications, people and divisions. Start anywhere and traverse in either direction.
Layer 4 — controls
Checks are authored through a guided interface, saved, versioned, scheduled on ingest or overnight, and re-run. Deterministic validators handle anything that does not need judgement, so a date check never costs a model call. Model-assisted validators handle the rest.
| Group | Checks |
|---|---|
| Dates and renewals | Contract expiry, renewal warning windows, per-person licence expiry. |
| Value and taxonomy | Data-content taxonomy, geographic restriction compliance and completeness, contract versus summed service value, service price to contract value ratio, delivery mechanism taxonomy, regulatory data classification. |
| Data quality | Required fields present, service name and description quality, duplicate service names, duplicate service assignments per person, SLA field completeness, orphaned services, applications without a cost code, grammar and capitalisation. |
| Enrichment | Vendor catalogue taxonomy and description sync, vendor catalogue pricing checks, industry sector classification suggest-and-validate. |
Severity, scheduling and target entity are set per rule. Findings carry an audit trail of who reviewed and resolved them.
Layer 5 — reporting
Period cost per person, active service lines, position against the median for their own cost centre, and month-on-month movement.
Month-on-month change broken into added lines, dropped lines and price updates — so a rise is explained rather than investigated.
Services held by people whose role, department or location does not match the profile for that service, listed for manager review.
Where peers in the same taxonomy use a lower-cost equivalent, the alternative is surfaced with an estimated difference.
Peer comparison is between users inside your own cost centres. Nexus One does not publish or sell cross-firm pricing benchmarks.
Capabilities
Each page below answers one question a specific person asks, states plainly what the capability does not do, and prints to a single-page PDF you can send on.
Adverse media alerts attached to the contracts, services, applications and users they actually affect, with concentration by parent group.
“How much are we spending with this group in total?”Name normalisation, alias handling, duplicate detection and parent-to-child rollup, with uncertain matches stopped at a person.
“Which of these numbers can I take to the board?”Configurable, scheduled, versioned checks with a severity-ordered review queue and an audit trail on every resolution.
“What are we buying, in categories I can compare?”Consistent classification of services and vendors by data content, delivery, latency, restriction and sector, reviewed rather than imposed.
These are capabilities. The domain pages — market data and technology spend — describe what they add up to for a specific buyer.
Capability — vendor risk
Adverse media alerts are a commodity. Knowing that the vendor in the headline sits behind eleven contracts, three critical applications and 140 users — and renews in nine weeks — is not.
The question it answers“A supplier is in the news this morning. How exposed are we, and what do we have to decide this week?”
A monitored vendor list drawn from your own estate, alerts linked to the contracts, services, applications and users they affect, and a concentration view by parent group — reviewable, attributable and exportable.
Sits with the vendor risk, resilience or COO function as often as with procurement. The graph is the same one used for spend; only the question changes.

Why the timing matters
Since January 2025, EU financial entities have been required to maintain a register of their ICT third-party contractual arrangements, assess concentration risk before entering new arrangements, and ensure specific provisions appear in ICT contracts. The register is held at entity, sub-consolidated and consolidated level and submitted annually to the national competent authority. UK-only firms sit under the FCA and PRA outsourcing rules and the Critical Third Parties regime instead, and UK groups with EU-authorised entities are in scope for those entities.
Most of what those obligations ask for — provider identity and hierarchy, contract references and scope, service descriptions and locations, subcontractor relationships, criticality — is the same data Nexus One already holds in order to answer a spend question. Checking whether a required clause is actually present across a contract portfolio is a rule, not a project.
Nexus One · thenexusone.ai · Vendor risk
Capability — vendor resolution
Nothing downstream is trustworthy while the same supplier exists five times under five spellings. Vendor resolution is the first thing Nexus One does, and the thing every other answer depends on.
The question it answers“How much are we actually spending with this group, across every entity and every region?”
A canonical supplier list with parent and child relationships, spend and contract counts rolled up to group level, duplicate contracts and overlapping services surfaced as findings, and an audit trail on every match decision.
This is the layer that makes negotiation leverage, concentration risk and duplicate detection possible at all. It is also the least visible work in the product.
Nexus One · thenexusone.ai · One supplier, however many names it arrived under
Capability — data quality
A dashboard tells you what the data says. A control framework tells you whether the data is worth reading. Nexus One runs configurable, scheduled, versioned checks and shows you what failed.
The question it answers“Before I present this, what in it is incomplete, stale or contradictory?”
A live issue count across the estate, a queue ordered by severity, a per-record view of what failed and why, and a rule set you can version, review and re-run on demand.
Usually the first thing that earns trust internally, because it is checkable. It is also the honest answer to ‘how do we know the AI got it right’.
Nexus One · thenexusone.ai · Know which numbers you can take to the board, and which you cannot
Capability — classification
Peer comparison, substitute analysis and out-of-profile detection all rest on one thing: services classified consistently enough that two records can be judged against each other.
The question it answers“What are we actually buying, in categories I can compare across desks and regions?”
A consistently classified service catalogue, comparable across desks and regions, that makes peer benchmarking within your cost centres, substitute identification and out-of-profile detection possible.
The least glamorous capability and the one everything else depends on. Without it, ‘cheaper alternative’ and ‘out of profile’ have no meaning.

Market data
Entitlements sit with people who have changed desk. The same exchange is contracted through four subsidiaries. Restrictions live in a PDF nobody opens until an audit. Nexus One was designed against this problem first.
Why this domain is hard
Cost attaches to named individuals and specific devices, not to a department line. Firm-level totals hide almost everything that matters.
One exchange group can appear as a dozen legal entities across regions. Without resolution, concentration and overlap are both invisible.
Geographic restrictions, display versus non-display use, derived-data creation and redistribution limits are all contractual conditions, not attributes.
Initial terms, renewal terms and successive multi-year schedules run concurrently. Flattening them loses the history you need at renewal.
What it produces
Every service line mapped to a named user, with their position against the median for their own cost centre and a flag where the service does not match their role, department or location.
Vendor entities resolved to their parent, contracts grouped by family, and duplicate service assignments across regions and business units surfaced as findings rather than left to be noticed.
Expiry and renewal windows tracked from the extracted contract terms, with auto-renewal clauses and notice periods carried through from the signed document.
Month-on-month change split into added lines, dropped lines and price updates, at firm, cost-centre and individual level.
Sizing it honestly
Published research puts procure-to-pay and post-signature leakage in a wide band of roughly two to eight per cent of contract value. We do not build business cases at the top of that range, or at the middle of it.
Our default target is 0.8 per cent of addressed spend — one-tenth of the upper bound — and every figure we put in front of you is derived at that level, against your own numbers, with the arithmetic shown.
Leakage ranges cited from published industry research. We will share the sources and their limitations rather than presenting them as our own findings.
Alongside what you already run
Most firms of any size already run a market data inventory or expense management platform, often with a managed service attached. Nexus One sits on top of it and keeps working with it.
What it adds is the layer those systems were not built for: contract terms structured to a standard and traceable to their clause, linked through services and applications down to the individual, and checked continuously by rules you control.
Technology spend
Application licensing, renewals and departmental allocation follow the same shape as market data: an agreement, the services bought under it, the systems they feed, and the people holding seats. The contract terms are simpler. The sprawl is wider.
What carries over
A software vendor is a vendor. A licence agreement is a contract family. A subscription tier is a service. A seat is a person. The graph does not care which category the spend sits in, which is why the second domain cost us a taxonomy rather than a rebuild.
Auto-renewal clauses, notice periods and expiry dates extracted from the agreements themselves, with the source clause attached to each date.
Vendors resolved to parents and services classified by function, so two products doing the same job across two business units become one finding.
Licences mapped to named holders and cost centres, with allocations that do not match a person's role or department flagged for review.
Where we focus
In a regulated firm, procurement is centralised and the estate is locked down. Discovering unknown applications matters less than governing the ones you have already signed for.
That is where Nexus One works: what the agreement actually permits, which entity it covers, when it renews, and whether the allocation still matches the person holding it — all traceable back to the clause it came from.
What the agreement permits, which legal entity it was signed with, what it obliges you to do, when it renews and on what notice — connected through the services and applications it covers to the individual holding the licence, inside an environment where the data does not leave your tenant.
A note on continuity
In August 2026 a well-established SaaS management platform announced it was shutting down, giving customers four days to export their application inventory, spend records and contracts before the service ended. That is a structural risk in any multi-tenant model, and it is not one you can diligence your way out of.
Nexus One runs inside your own cloud tenant. The graph, the extracted contract terms and the audit trail live in your infrastructure, in a database you control. If we disappear tomorrow, your data does not go anywhere.
Security & deployment
Nexus One is deployed as a single-tenant application inside your own Azure or AWS environment. This page is written for the people who will review it before a first meeting is agreed.
Architecture
The application and its graph database are deployed into your subscription, in the region you nominate. Your operational data is not pooled with any other client's.
Reasoning over contract text and spend records runs against a model inside your boundary. The rules engine uses deterministic logic and fuzzy matching first, so a large share of checks involve no model call at all.
New versions are pulled by you when you choose. There is no vendor-initiated push into your environment.
Read-only and administrative roles, with review and resolution actions attributed to the user who took them.
Configuration and credentials handled through platform-native secret management, with managed identity where the deployment pattern supports it.
Where internal documents and external reference material disagree, your signed documents are treated as the more authoritative source.
Vendor intelligence
Service taxonomies, vendor descriptions and classification data are assembled from publicly available and licensed sources, and from the procurement documents you provide. Enrichment is delivered to your environment as a catalogue and taxonomy update.
Due diligence
A security pack, our data processing agreement and a completed due diligence questionnaire are available on request, before any data is exchanged. If your team works from its own questionnaire, send it over and we will complete that instead.
Contact
A short note is enough to start. We will come back to you with a straight answer about whether Nexus One fits what you are dealing with.
