Ask your portfolio anything
Ask your own data in plain language. It can record a call or build a dashboard. By default it asks before every change; in Auto it goes ahead, and every change is in the change log.

Zahlenwerk and the team behind it impressed us not only with the implementation of the software solution. Together, we were able to achieve extensive process optimizations within our team.
What people use it for
- Tracking capital callsTrack every capital call and distribution against the commitment it belongs to. Notices arrive by email, get parsed into records with the PDF attached, and the unfunded balance updates itself.
- Reading capital account statementsQuarterly capital account statements parsed into portfolio records (NAV, called, distributed, unfunded), with every figure linked back to the page it was read from, and low-confidence fields held for review.
- Private markets reportingReporting built for illiquid positions: fund LP interests, SPVs, direct holdings and secondaries, with IRR, TVPI and DPI computed from your own statements rather than copied from the GP's report.
- Consolidated reportingOne current picture across every entity, vehicle and bank: liquid and illiquid positions, per-entity books, multi-currency consolidation, and a figure you can drill from the group total down to the document.
- Computing IRR, TVPI and DPIPortfolio performance computed from the calls you funded and the distributions you received: IRR, TVPI, DPI and RVPI, per position and consolidated, with the cashflows behind every figure.
Your numbers, one prompt away
Wealth Management by Zahlenwerk ships with an MCP server, so Claude and ChatGPT can read your portfolio directly. Ask for exposure, reconcile a call, or draft the quarterly update, all grounded in your real data.

ChatGPTQuestions we get asked
What is Wealth Management by Zahlenwerk?
It is one workspace for a firm's LP investments, the books behind them, and the documents they came from. Statements are ingested by email, parsed into structured records, and turned into positions, performance and reporting you can query. It is currently in beta.
Who is it built for?
Family offices running several entities and many manager relationships, and investment managers with funds, SPVs and direct holdings. Both cases share the same problem: the numbers, the documents and the books live in different places.
Which documents can it read?
Three are parsed into records today: capital account statements, capital call notices and investor reports, from PDF, Word or Excel. Every extracted figure stays traceable to the page it came from, and low-confidence extractions wait in a review queue until a person signs off. Another twenty-nine types (K-1s, LPAs, SPV updates, grant letters) are recognised and stored, but not yet parsed. We add extractors one at a time, and we would rather tell you which is which.
How do documents get into the system?
Forward them to your team's private drop-address, or upload them directly. A forwarding rule in your mail client or a shared inbox like reports@firm.com sends them on automatically. Only mail from senders on your accepted list is imported, only PDF attachments are read, and an AI filter keeps payslips, invoices and other unrelated mail out.
Which performance metrics does it calculate?
IRR, TVPI and DPI per position and rolled up, with capital calls, distributions, multi-currency FX and fund roll-ups behind every figure. Each number can be traced back to the statements it was derived from.
Does it connect to Claude and ChatGPT?
Yes. It ships with a built-in MCP server with proper OAuth, so Claude and ChatGPT can query your portfolio directly. There is also an internal assistant grounded in your own data. By default it asks before every write; switch a chat to Auto and it makes changes in the app without asking, while anything that leaves the app still asks.
Does it replace our bookkeeping?
It keeps a full set of books per legal entity, on your own chart of accounts if you have one: bank statements, coding, manual journal entries, loans and interest, then reports and a tax-advisor package for your accountant. Receipts can go to DATEV by email. It is a file handover, not a live DATEV or Xero integration.
How do we get access?
Access is by request while the product is in beta. Tell us about your firm and we will get in touch.

Notes on what we build, and why.
Live 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.A 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.Planning 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.
