Family office
intelligence from every holding to the next decision.
One private operating layer connecting portfolio data, source documents, historical reviews, commentary, and actions—across listed shares, private stakes, funds, overseas capital, crypto, and cash.
What changed
this month?
Movement, context, source, and next action—held together.
The family already owns the data. It just doesn't yet own the intelligence between it.
Past values get overwritten. Context lives in someone's head.
Broker statements, fund notices, valuations, and updates live apart.
Commentary, owners, due dates, and follow-through detach from the number.
Your portfolio, designed like a product.
Desktop for the review table. Mobile for the family. Same source-traceable layer, framed the way Apple frames its best work — representative interface, not client data.
MacBook view — representative interface · not client data
iPhone view — same layer, thumb-ready
The monthly review, ready while the month still matters. Not after the hunt.
Every month, answer the same four questions in one place: what changed, why it changed, what needs checking, and what happens next.
One view of the month.
Representative data · values are illustrative, not client information.
Every holding belongs together. Not every holding behaves the same.
Zosma preserves each asset class's logic—then brings the family back to one reviewable portfolio.

Ask your portfolio. Get the paper behind the answer.
A private financial AI built from the family's own portfolio data, source records, and past reviews—not a generic model guessing from the outside.
Three items need attention.
Two private stakes need their valuations re-checked. Cash is down from last month, and one company update is late. Each item is linked to its underlying record.
Start with this month. Build the family's operating layer over time.
The first useful system is the monthly review you already run. Screening, tax, Tally, and compliance can join the same private foundation later.

Your data never leaves you.
Family capital is the most sensitive data there is. Zosma runs where you choose — on-prem, VPC, or Mumbai private cloud. Open, auditable models. Zero training on your data. Zero resale.
Private deployment — inside your perimeter, not ours
At-rest and in-transit encryption, role-based access, and a complete audit trail. Your team controls who sees which holding — down to the line item. No backdoor, no shadow copy.
Open models you can audit
Built on open weights (Llama, Qwen, Mistral variants) — not a black-box API. Inspect prompts, weights, and every source citation. Self-hosted and version-pinned so the same question gives the same answer tomorrow.
Nothing shared. Nothing sold. Ever.
No data leaves for training. No telemetry to a global platform. Every answer links back to the workbook or statement it came from — because trust is a citation, not a claim.
