Fintech & Banking · Generative AI & RAG

Your policy library, answerable.

Retrieval over circulars, product terms and internal procedure — returning the clause, the revision date, and a link to the page it came from.

  • Retrieval pipelines
  • Fine-tuned domain models
  • Multimodal (text · image · voice)
  • Eval + guardrails

What we build

Generative AI & RAG for fintech, specifically.

  • 01

    Frontline policy assistant

    Branch and support staff ask in plain language and get the current clause with its effective date — plus an explicit warning when the retrieved revision has been superseded.

  • 02

    Product terms across a changing catalogue

    Fee schedules and eligibility rules change per product, region and vintage. Retrieval is scoped by those dimensions so a 2024 answer can't leak into a 2026 question.

  • 03

    Regulatory change triage

    New circulars are diffed against your existing procedure set, and the assistant drafts the list of documents that now contradict it for a compliance officer to confirm.

What we measure

  • Answer accuracy against a graded set drawn from your own documents
  • Citation correctness — does the linked passage support the claim
  • Refusal rate when retrieval is weak (a feature, not a fault)
  • Median time to find an answer, before and after

Instrumented in week one and reported weekly. These are the numbers the engagement is judged on — not a forecast of what they'll be.

Constraints

What has to be true in fintech.

  • 01

    Every answer needs a receipt

    We ground responses in your own documents and return the citation with the answer. If the retrieval finds nothing, the system says so instead of improvising — that refusal path is tested like any other feature.

  • 02

    Models never move money

    The LLM classifies, drafts and retrieves. Balance changes, limit increases and refunds run through your existing deterministic services behind an approval step, with the full prompt and decision written to an audit log.

  • 03

    Data residency is a build constraint, not a setting

    For RBI, PCI-DSS and SOC 2 scopes we deploy inside your VPC or account with zero data egress, and pick models — including open-weights — that can legally sit where your data sits.

How it runs

The Generative AI & RAG engagement, step by step.

  1. 1

    Data inventory

    What docs / databases / APIs / feeds matter? What's PII vs public? What changes daily vs quarterly? We map it before writing code.

  2. 2

    Retrieval architecture

    Hybrid (BM25 + vector) retrieval, chunking strategy, reranking, citations. Tuned for your domain not a generic benchmark.

  3. 3

    Eval suite

    Real-world question set with golden answers. Faithfulness, context precision, latency. So you know when changes ship a regression.

  4. 4

    Guardrails

    Prompt-injection defense, PII scrubbing, refusal patterns, output schemas. Especially critical for customer-facing deployments.

  5. 5

    Production + iterate

    Cost-effective inference (caching, fallback models), monitoring, weekly eval reports. Fine-tune when the data justifies it.

FAQ

RAG for banking and financial services: your questions.

  • Our documents contradict each other. What then?

    The system surfaces the conflict rather than picking a winner: both passages, both dates, and a flag. That surfacing is usually worth more than the answering — most libraries we index have contradictions nobody had noticed.

  • Can we keep customer data out of the model entirely?

    Yes, and for most policy use cases you should. The index holds documents, not customer records; where an answer needs account context we inject the specific fields at query time and drop them after, rather than embedding anything customer-identifiable.

  • Should I use RAG or fine-tuning?

    RAG for facts that change. Fine-tuning for style, format, or domain reasoning. Most production systems use both — and we'll tell you which mix is right after a 1-week discovery.

  • Can I use my own LLM (open-weights)?

    Yes. We work with Llama, Mistral, Qwen, and similar — useful for data residency, cost predictability, and air-gapped environments.
