Knowledge systems, grounded in your data.

We build retrieval-augmented generation systems that answer from your proprietary corpora, cite their sources, and keep sensitive data inside your perimeter. The result is an institutional knowledge layer your teams can trust under scrutiny.

What we build

01

Grounded retrieval

Hybrid dense and lexical search with reranking, tuned to your corpus so answers rest on the most relevant evidence rather than the model's priors.

02

Citations by default

Every response links back to the source passages, paragraph and page, so reviewers can verify claims and the system withstands audit.

03

Knowledge graphs

Entity and relationship modelling over your domain, enabling multi-hop questions and semantic search that respects how your business is actually structured.

04

Data sovereignty

Embeddings, indexes, and inference run inside your perimeter, with document-level access controls enforced at query time. Nothing leaves your tenancy.

05

Hallucination control

Groundedness checks, answer-refusal when evidence is absent, and continuous evaluation against curated test sets keep fabrication out of production.

06

Production MLOps

Connectors to your document estate, automated re-indexing as content changes, and live monitoring of citation accuracy and answer quality.
