Past work

A workforce allocation dashboard for Airbus

When Airbus wound down its Beluga transport team, Laura built the tooling that re-allocated a 1,000-person organisation. Matching scripts compared every job profile in the group against every other by shared competencies and target level, so each role being retired came with a ranked shortlist of the roles its people could step into.

Salesforce reporting SPREAD AI's sales team actually uses

A reporting tool built on live Salesforce data, including a contact relationship map that sales users actually adopt. Records are continuously out-enriched through Clay and Apex automations, so the picture stays current without anyone re-keying data.

Founder-led.
One standard.

Zahlenwerk Studio is run by Laura Nogales De La Cruz and Lukas Beier from Berlin-Charlottenburg. No account managers, no hand-offs. You work directly with the founders, who scope, build, and take your product to market.

A process engineer and a designer with a go-to-market background: we cover the whole path from messy data to a product people actually use, and to the market it's built for.

Notes on what we build, and why.

EngineeringLive portfolio dashboards in Claude, from your own Zahlenwerk dataClaude can now build dashboards that fetch fresh data every time someone opens them. With the Zahlenwerk connector, that data can be your portfolio. How it works, what we changed to support it, and what to know before you share one.DataA small model for routine questions, and where we stop itMost questions in a document pipeline are small. Jev answers them in about half a second, for teams that switch it on, and only decides when it is at least 0.9 sure. What it sees, where it runs, and what it is not allowed to do.PortfolioPlanning for unfunded commitments in a family officeUnfunded commitment is the number a family office's liquidity plan stands on, and in most spreadsheets it is wrong. How to calculate it properly, where it goes wrong, and how to plan for the calls still to come.
