Software built
around numbers.

We are an independent studio designing and engineering software, from data infrastructure to the interface on top of it.

Zahlenwerk, literally “a work of numbers”. We take the data everyone else finds tedious and turn it into products people actually want to use.

Product engineering

Full-stack build

Full-stack development of data-heavy products: parsing pipelines, APIs, and interfaces that make complex data legible.

Product design

Interface & identity

Interfaces, identity, and typography for products where clarity is the feature. Designed and built by the same hands.

AI & data infrastructure

Data & MCP add-on

Document parsing, structured extraction, and MCP integrations that connect your data to Claude, ChatGPT, and whatever comes next.

Our products

Wealth Management by Zahlenwerk

Our own product, now in beta. One workspace for family offices and investment managers: every LP position, the books, the documents behind them, and an assistant that reaches your portfolio through Claude and ChatGPT.

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.

Two people.
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 two 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.

Laura Nogales De La Cruz

Co-founder · Process engineering & operations

Laura turns tangled operations into clean, repeatable systems. A process engineer with an M.Sc. in Digital Transformation, she maps the process, models the data, and makes sure what we ship holds up once real people and real numbers hit it.

Lukas Beier

Co-founder · Design & go-to-market

Lukas shapes how the product looks, reads, and reaches the people it's for, from the first pixel to launch. A communication designer with an MBA, he pairs craft with a growth and go-to-market instinct sharpened across venture, health, and AI.

About the studio

What does Zahlenwerk Studio do?

We are an independent software studio in Berlin. We design and build data-heavy products end to end, and we run our own finance software, Wealth Management by Zahlenwerk, for family offices and investment managers.

Who is behind Zahlenwerk?

Laura Nogales De La Cruz and Lukas Beier, a designer with a go-to-market background and a process engineer. The two of us scope, design and build every project ourselves, so there is no layer between you and the people writing the code.

Do you take on client projects?

Yes. We split our time between client work and our own product. Past work includes workforce tooling for a 1,000 person reorganisation at Airbus, sales reporting at SPREAD AI, and marketing sites you can edit by talking to them.

What is Wealth Management by Zahlenwerk?

Our own product: one workspace for LP investments, the books, and the documents behind them, with automatic report ingestion, structured extraction with a full audit trail, and an MCP server that connects a portfolio to Claude and ChatGPT. It is in beta.

Where are you based?

Berlin-Charlottenburg. We work with clients across Europe, and the site is available in English, German and Spanish.
