The problem

Most of the stack does one thing well. The rest is spreadsheets.

Legacy consolidation runs on banking-era rails built for RIAs. The decade-old challengers still need point tools, a data team and a basis-point fee to get a clean quarterly out the door.

Why Atrean

Not an old stack with AI bolted on.

What family offices inherited

Consolidation built a decade or more ago, much of it on banking software for RIAs. Each system does one thing well, so the office bolts on a pacing workbook, a document tool, a data room and a spreadsheet to close the gaps, and pays basis points for the privilege.

What we built instead

One book built from the GP’s paper and the custodian’s statement, a deterministic pacing engine underneath and an entitlement-gated query layer on top. Designed with the CIO of a working family office and parity-tested against their IC workbook.

Engagement

Live in days. Priced flat.

A flat annual fee, priced on the software, not your AUM. A strong vintage year doesn’t reprice the stack, and a lean office isn’t priced out of institutional tooling.

Security

Built like the balance sheet it protects.

Every family’s book held apart from every other, end to end. Clears a bank vendor-risk review or a family’s outside counsel without a remediation plan.
