Decision-grade data, responsibly applied.

Governed lakehouses, model ops, and responsible AI — built for enterprises that need provenance, not promises. We design the platform, ship the models, and operate both with lineage, bias monitoring and human-in-the-loop controls.

What's inside

Six interlocking capabilities, one governed spine.

Every Data & AI engagement bundles the platform, the models and the governance — because models without lineage are liabilities, and lineage without models is a dashboard.

D·01

Data platform

Medallion lakehouse with lineage, catalog and policy enforcement — the foundation under everything downstream.

  • Bronze / Silver / Gold with contracts
  • Unity Catalog / Purview / Atlan
  • Row-level policy & tag-based access
D·02

Analytics & BI

Semantic layers, governed metrics, and self-serve BI — so every number on the CEO's dashboard traces back to a trusted source.

  • Metric layer (dbt / Cube / Looker ML)
  • Embedded analytics for clients
  • Board-grade data products
D·03

MLOps

Model training, deployment, monitoring and drift detection — the boring infrastructure that turns notebooks into reliable capability.

  • Feature stores + training registries
  • Champion/challenger + shadow eval
  • Drift, bias & quality monitoring
D·04

Generative AI

RAG, fine-tuning and agent systems with retrieval grounded in your catalog — not a wrapper on a public endpoint.

  • Retrieval on your governed corpus
  • Eval harnesses + red-team
  • Human-in-the-loop & policy gates
D·05

Responsible AI

Bias testing, explainability, policy gates and clear appeal pathways for humans affected by model decisions.

  • NIST AI RMF + EU AI Act alignment
  • Model cards & impact assessments
  • Human override + appeal workflows
D·06

Data mesh

Domain-aligned ownership with central platform governance — federated, interoperable, and socio-technically realistic.

  • Domain team enablement + golden paths
  • Interoperable data products
  • Central platform + federated teams
How we engage

Four phases — from "can we trust this number?" to trusted capability.

Every data program runs on the same spine: build trust first, then models, then agents. We don't ship LLMs on a spreadsheet.

Phase 01 · 2 wk

Assess

Data estate audit, use-case shortlist, and a responsible-AI risk screen. Outputs a sequenced roadmap with a "do nothing" option on the cover page.

Deliverable · Roadmap + RAI risk register
Phase 02 · 4–8 wk

Platform

Stand up the lakehouse, catalog, lineage and access-policy spine. Ship the first trusted data products in production, not in a staging bucket.

Deliverable · Governed platform + 3 data products
Phase 03 · 8–16 wk

Models & agents

Ship the first two production models — with eval harnesses, monitoring and appeal pathways — and the RAG system grounded in your catalog.

Deliverable · 2+ models live, with model cards
Phase 04 · continuous

Operate

MLOps, drift monitoring, governance reviews and responsible-AI committee support — fully managed or co-managed with your analytics team.

Deliverable · 24/7 ops + monthly RAI report

Technology

Platform-agnostic, governance-opinionated.

We pick data stacks by residency, data gravity and team readiness — and hold every choice to the same lineage and policy bar.

Featured engagement

A global bank — 4,200 models, governed across 14 jurisdictions.

A top-20 global bank engaged us to rebuild its model-governance backbone — moving from fragmented notebooks to a centralized, jurisdictional registry with policy gates baked into deployment.

Top-20 global bank · 14 jurisdictions
"We can now show our regulators, in under fifteen minutes, exactly which model made which decision and what data it used. That alone justified the program."
Chief Data & Analytics Officer Top-20 global bank
CASE 09 · Model governance · 9 months

From 4,200 scattered notebooks to a single governed registry.

We stood up the registry, migrated the top 400 models under lineage, automated model cards, and delivered regulator-ready evidence packs on a button press.

Frequently asked

What data & AI leaders ask before signing.

Do you prefer Databricks or Snowflake? +

Neither religiously. We staff certified engineers on both, and pick by data gravity, existing licensing, team readiness and residency. We'll tell you honestly when the choice doesn't matter.

How do you approach generative AI? +

RAG-first, grounded in your governed catalog, with eval harnesses and human-in-the-loop controls before any agent touches a production workflow. We decline "wrap an LLM over prod" asks.

Where does model governance live? +

In a centralized registry with automated model cards, policy gates in CI/CD, and drift monitoring bound to business-owner alerts. Governance is a platform feature, not a quarterly audit ritual.

What about data residency? +

We build for jurisdictional residency from day one. Our reference architectures keep PII in-region, with cross-region work limited to tokenized aggregates under explicit agreements.

Can you align to EU AI Act & NIST AI RMF? +

Yes. Our responsible-AI framework is an active mapping of both, refreshed every quarter as secondary legislation lands. Every deployed model has a model card, a risk tier, and a defined appeal pathway.

Do you hand off to our team? +

Absolutely — and it's in the SOW. Every engagement includes a pairing window and a handover packet. Many clients co-manage long-term, with our team staying on MLOps while theirs owns modeling.

Adjacent practices

What we'll often pair with Data & AI.

Data doesn't travel alone. Most programs bundle at least one of the below, staffed by the same senior team.

Start a conversation

Turn data into decision-grade capability — responsibly.

Share a brief, a regulatory deadline, or a model that's worrying you. A senior partner responds within one business day with a calibrated engagement shape.

What you'll get back
  • Calibrated roadmap + RAI risk screen
  • Named principal on the follow-up — not a BD rep
  • Three references in your regulatory vertical
  • NDA, MSA and governance-charter sheet on day one
