AI covenant monitoring for private credit: how a Ryz pod built it

A walkthrough of how a senior Ryz AI pod built covenant monitoring for a private credit lender: what it reads, how it calculates, and where analysts stay in control.

AI covenant monitoring for private credit reads each credit agreement and its amendments, turns the financial covenants and defined terms into structured rules, then checks every compliance certificate and set of borrower financials against those rules and shows the credit team the headroom, with a source for every number. This guide describes how a Ryz AI pod built that system for a private credit lender: the problem, the architecture and the analyst workflow. The client is confidential and we do not publish figures for this project, so there are no performance numbers here, only how it works.

The problem the lender brought us

Private credit portfolios are built from bespoke agreements. Two loans to similar borrowers can define EBITDA differently, cap add-backs differently, step their ratio thresholds down on different schedules and grant different cure rights. Each quarter, borrowers send a compliance certificate and financial statements, and an analyst has to:

That work is careful reading more than arithmetic, and it scales with the number of borrowers, not with the size of the team. The lender wanted analysts spending their time on judgment, not on locating the same clause in a different agreement again and again.

What the pod built

A pod for this kind of build pairs a tech lead with engineers covering extraction and evals, ingestion and the rules engine, and the review screens, all working on the lender's team in its cloud and repos. The system has five parts.

1. Credit agreement extraction

Agreements, amendments and waivers are parsed with layout preserved, so section numbers, tables and cross-references survive. A model extracts each financial covenant (for example a maximum total net debt to EBITDA ratio, a minimum fixed charge coverage ratio, a minimum liquidity test or a capital expenditure limit), its threshold schedule, test dates, testing period, the defined terms it uses and any cure rights. Every extracted field stores the page and clause it came from.

2. A versioned covenant record

Amendments are the hardest part. The system keeps a version history per facility: the original term, each amendment that changed it, and the effective date. When an analyst opens a borrower, they see the covenant as it reads today and every change that led there, each linked to the source document. Analysts approve the extracted record before it is used for testing, and corrections go back into the evaluation set.

3. Compliance certificate and financials intake

Quarterly packages arrive as PDFs and spreadsheets in many layouts. The pipeline classifies each file, extracts the borrower's reported covenant calculations and the underlying line items, and maps them to the definitions in that borrower's agreement. Ingestion is idempotent, so a re-sent package does not create a second test result.

4. Independent recalculation and headroom

The rules engine is ordinary code, not a model. Given the approved covenant record and the extracted financials, it recalculates each test, applies add-back caps where the agreement defines them, compares the result to the borrower's own calculation and computes headroom against the threshold for that test date. Any gap between the borrower's number and the recalculated number is flagged with both workings shown side by side.

5. The analyst review queue

Analysts work from a queue sorted by risk: tight headroom, a calculation mismatch, a missed reporting deadline or a definition the model was unsure about. Each item shows the value, its source, the model's confidence and the history of who approved or corrected it. The system drafts the headroom summary for the portfolio review, and the analyst edits and signs it.

The split matters: models read and extract, code calculates, people approve. A model never decides whether a borrower is in compliance. It proposes the terms; the analyst approves them; the rules engine tests them.

Where covenant AI goes wrong, and how the pod handled it

How it connects to the rest of the credit workflow

Covenant monitoring rarely stands alone. The same document foundation supports borrowing-base certificate automation for asset-based facilities and underwriting document processing at origination, where the agreement terms are first negotiated. Reusing the parsing, retrieval, eval harness and review screen means the second workflow is mostly new rules and new tests, not a new platform. The broader pattern is described on our financial services AI engineering page and, for agent-style workflows, AI agent development for financial services.

What a build like this costs with Ryz

Typical Ryz cost is $7,000 to $15,000 per engineer per month, with leads from $15,000, quoted per team. A pilot pod of a tech lead and two senior engineers starts at $35,000 per month ($15,000+ plus 2 × $10,000 to $15,000). A full pod of about seven senior engineers starts at $75,000 per month. Project cost is team size × months × monthly rate. You meet the named engineers before the engagement starts, engineers can start in under two weeks once you say go, and the pod works on your team, in your cloud and repos, reporting to your leads, as one accountable team.

When this is not the right approach

If you monitor only a few facilities and the agreements are highly standardized, a spreadsheet template and a careful analyst may be enough. If you would rather license a packaged portfolio monitoring platform than build in your own stack, a platform vendor fits better. Building pays off when agreements are bespoke, the portfolio is growing, and you want the extracted terms and test history in your own data platform.

FAQ

What is AI covenant monitoring?

It is a system that extracts financial and reporting covenants from credit agreements, checks each borrower's compliance certificate and financials against them, and shows headroom and exceptions to the credit team. Models read the documents; deterministic code does the math; analysts approve.

Does AI covenant monitoring replace credit analysts?

No. It removes the searching, reading and re-keying. Analysts still approve the extracted terms, review exceptions and make every credit call.

How does the system handle amendments and waivers?

Each facility keeps a version history of every covenant with effective dates and links to the amending document, so testing always uses the terms in force on the test date.

Can it run in our own cloud?

Yes. A Ryz pod builds in your AWS or Azure accounts and repos, calls models through endpoints you approve, and keeps agreements, borrower files and results in your environment. You own all code and IP.

How much does it cost to build?

Cost is team size × months × monthly rate. Ryz engineers typically cost $7,000 to $15,000 per month each; a three-person pilot pod starts at $35,000 per month.
