The challenge

Reaching the data was the bottleneck.

Our client is a multinational manufacturing organization that runs finance across a portfolio of brands and multiple ERPs, with all of it flowing into an enterprise data warehouse. The people were capable and the data was good. Getting clean answers out of it was the constraint.

Every new report was an IT build measured in weeks. Month-end close leaned on manual, sample-based reconciliation that consumed hours each cycle. The team’s capacity was spent on the work between the systems, which left little room for the analysis that actually moves cash.

The goal was simple: turn a question into a trustworthy answer in minutes, not weeks.

What stood in the way

What we built

Your data warehouse, now in Claude.

We connected Claude directly to the company’s enterprise data warehouse and taught it the business. It carries the warehouse’s structure and the company’s own definitions — the brands, entities, and chart of accounts — so a plain-English question returns a branded report that reconciles to the company’s existing BI, dollar for dollar.

The connection is read-only and runs inside the company’s own cloud environment, under its own controls. Anyone on the finance team can ask for a report in plain language and have it in minutes. What used to require an IT ticket and a wait of weeks now takes a sentence.

How it works
  • Ask in plain English — no SQL, no report spec
  • Claude queries the warehouse directly, read-only
  • Answers come back branded and reconciled to your BI
  • A new report takes minutes, not an IT build
How it stays safe
  • Runs inside the company’s own cloud environment
  • Read-only access, controlled by the company’s IT
  • Every figure checked with deterministic math
  • An independent review before a number is trusted

Then we made sure it didn’t stay ours. A three-day onsite bootcamp and weekly working sessions put the building in the hands of the company’s own finance and IT teams.

What the first two weeks produced.

Hands-on enablement began with a three-day bootcamp. Within two weeks, the team was running real work on what they had built.

Day 2 of training
Live
First automations shipped.

By the second day, the team had built and demoed its first working automations against the live warehouse.

End of week 1
~1 FTE
The capacity, built.

By the end of bootcamp week, the automations behind roughly a full-time person of capacity were built and demoed.

Week 2
Daily
Running the business.

The automations were on schedule and in daily use across AP and AR, with the team building the next ones on their own.

New capabilities

What the team couldn’t do before.

Some of the return doesn’t show up as hours saved. It shows up as things the team simply couldn’t do before.

What’s next

Agents run the work, with people in the loop.

The foundation is live and the client’s team is building on it. The next phase changes who drives the routine work.

Each step keeps a person in control and leaves the capability inside the company.
