Neurosymbolic agents · built for regulated finance

The back office that never guesses.

Nien runs operations with neurosymbolic agents that execute like software and answer like staff. Raw language models improvise; ours are not allowed to. Every action is planned in plain English, executed deterministically, logged to the line, and approved by your people. Nothing improvised. Nothing unexplained.

The uncomfortable part

Your in-house LLM pilot is going to fail.

Not because your team is weak. Because the architecture is wrong. A language model wired straight into operations is a probabilistic actor in a deterministic job, and it fails exactly where you can afford it least.

01

It gambles

An LLM samples its answers. Right 98% of the time sounds impressive until you do the arithmetic: that is roughly 800 wrong lines in a 41,000-row file, and the model cannot tell you which 800.

02

It cannot show its work

Ask it why twice and you will get two different answers. There is no replayable trail, and an audit that cannot be replayed is an audit you fail.

03

It demos well, then dies in production

The pilot works on clean samples. Production is messy exports, edge cases and drift, and confident wrong output looks exactly like clean output until the penalty letter arrives.

No amount of prompting fixes architecture. The fix is neurosymbolic.

The neurosymbolic answer

Probabilistic where it reads. Deterministic where it acts.

Language models are brilliant readers and unreliable actors. Nien is neurosymbolic: neural models read your documents and your intent, and a symbolic rules engine plans, checks and executes. The generative half never acts alone. What moves money, files returns, or touches a ledger runs the same way every single time.

01

Deterministic by design

Same input, same output, every run. Agents follow written procedures, and a strict symbolic engine verifies every neural reading before anything is committed. Zero improvisation in the money path.

02

Everything in writing

Every step lands in a plain-English ledger: what was done, why, from which source document, under whose approval. Your auditor reads it like a diary, and can replay any run and get the identical result.

03

Knows when to stop

Anything ambiguous halts and escalates to your maker-checker with the evidence attached. Humans approve, agents execute, and override is a design principle, not a support ticket.

Capability

What good looks like, without the adjectives.

Reads anything

Bank files, spreadsheets, portals, scanned paper, forty-column exports with merged cells. If your team can read it, the agents can, and they read all of it, not a sample.

Reconciles at any scale

Millions of rows tied out line by line. The fraction that refuses to match is surfaced with its reasons attached, not buried in a tab called FINAL_v7.

Never misses a deadline

Cutoffs, calendars and filing windows are first-class objects in every procedure. The agents work the clock so your team stops working weekends.

Remembers everything

Every exception your team resolves becomes a rule the system keeps. The back office gets sharper every week, and the knowledge stays when people move on.

Written in your language

Procedures live in plain English your ops lead can read, edit and approve. Changing a process is editing a paragraph, not raising a ticket and waiting a quarter.

Fits what you have

No rip-and-replace, no six-month integration. Agents work from the exports, inboxes and portals you already use, starting the week they arrive.

Regulated by default

Built to survive an audit, not just a demo.

We assume your regulator, your auditor and your board will read what our agents did. So we build as if they are already in the room.

A complete trail, always

Every action is logged to its source line and replayable deterministically. There is no such thing as an unexplained entry.

Maker-checker, native

Approvals flow through your chain of command, inside your policies. The system enforces four eyes; it never becomes the second pair.

Your data stays home

Hosted in India, logs retained and inspectable, evidence exportable on demand. Residency is the default, not an enterprise add-on.

Vendor-audit ready

Audit rights, inspection access, exit and secure-purge plans are our standard paper, not a negotiation. Bring your outsourcing checklist.

The human part

It ships with an engineer.

Every deployment comes with a forward-deployed engineer who installs the agents, hardens them on your quirks, and stays accountable for the outcome.

A named human with a response commitment, not a support portal. And everything they build for you becomes product, which is why the system keeps getting better without getting more expensive.

Next step

See it run on your own files.

Bring one messy export and one deadline. We will show you the rest.
