Nyx Foundry

Nyx Foundry

A fintech holding company. Software for finance operations that shows its work on every number and never touches your money.

Built in New York by a former debt-capital-markets banker. The agents draft and check the math. A person signs off before anything moves.

How it worksWhy the output can be trusted
01 / Deterministic core

No number comes from a model.

Every figure is computed by a tested core in exact decimal math (actual/360 day-count, half-up rounding), not generated by an LLM. Its golden tests pass to the cent before any client work runs.

02 / Cited extraction

Every claim carries its source.

Agents read the documents and must quote the exact language behind each value they pull. If a term is not stated, they say so. They extract and cite. They do not invent.

03 / Human ratifies

Nothing binding runs on its own.

Agents draft and flag; a person approves before anything is sent or acted on. The system finds the break. You decide what to do about it.

Read-only

Products reconcile, compute, and instruct. They never custody, move, or hold funds.

NDA first

No document moves before a mutual NDA. Delivery is an in-person hand-off or an expiring, access-logged secure link, never a plain email attachment.

No training, no retention

Documents are processed to extract terms, never stored to train a model. Anthropic is engaged as a Zero Data Retention subprocessor.

Processing audit log

Every run records that a document was processed: a timestamp, a SHA-256 fingerprint, and a result count. Never its content.

Nyx Foundry LLC is a software company. It is not a bank, is not FDIC-insured, does not take deposits, and does not hold or transmit customer funds. Nothing on this site is financial, investment, or legal advice.

Who runs thisOne person, reachable

Nyx Foundry is run by one person: a former debt-capital-markets banker, based in the Financial District, New York.

If you run a small credit fund, I will run this on one of your own loans, in person and under NDA, at no cost. You keep the report. Nothing is stored and nothing leaves with me.
