For the CFO, controller and CIO

The answer is in the spreadsheet. So is the problem.

Every answer comes back with the rows behind it, yours to defend.

IGNITIONWhat is our idle cash costing us?
$397K
a year of forgone return on cash no reserve, call or bill has a claim on, at the hurdle
WARNING$33.0M in cash; $21.8M of it is already spoken for: the $6.0M reserve, $12.0M of capital calls and dated bills, and cash owners pass to the entities they fund. $11.2M is idle, $397K a year short of the 6% hurdle after what each account already earns; $8.7M of it has no recorded claim on it, the rest is the foundation's, for grants. Counting cash against the reserve alone says $1.3M: that treats cash the funds will call as idle.

The week you have now

Where the week goes.

The tie-out: Do the systems agree?

Two exports, side by side, by hand.

The question: “Quick one”

Simple to ask. A day to answer.

The deadline: The filing nobody owned

One calendar, living in three inboxes.

The audit: “Where did this number come from?”

A tab, referencing an export from March.

The week after

The questions, answered before you open anything.

Month-end, every night

Your three systems, tied out before you open anything.

Built and tested end to end. It switches on per entity the day you connect it.

CheckAgainstTolerance
Open bills in Bill.comAccounts-payable account in Intacct$1.00 or 0.5%
Portfolio value ex cash in AddeparInvestment accounts in Intacct$100 or 1% when the books are carried at market; otherwise reported as the unrecorded mark
Cash held at custodians, in AddeparCash accounts in Intacct$100 or 0.5%, informational

So the guarantee starts after your first successful tie-out, not at signature.

Asked by controllers
Does it replace our reporting platform?

No. It reads from it. Sage Intacct, Bill.com and Addepar connect directly, one entity to one set of books, and are tied out to each other every night; Addepar, Black Diamond, Orion, Tamarac and your custodians are read from the exports you already produce. Direct bank and custodian connections are built and switch on per family, and the exported book is the one your auditor already follows. You keep the systems of record; ParetoAlpha answers questions across all of them and checks that they agree.

How does it handle the positions the platform gets wrong?

FORTRESS classifies every position by the downside it shares, records the rationale, and logs your corrections. A framework that cannot find a position, a benchmark or a document says so rather than estimating around it. Your override is recorded with your name and the date.

Can our auditor follow it?

Yes. Every answer shows the rows, filters and policy figures that produced it, and any action the system prepares is staged and approved by a named person, with the approval logged. The source chain is the point.

What does month-end look like afterwards?

The tie-out you do by hand is already done. Every night, per entity: open payables in Bill.com against the AP account in Intacct, Addepar's value against the investment accounts, custodied cash against the ledger, each with the tolerance written down and every break explained with both figures and its likely cause. The five frameworks run against the new book every week. The consolidated questions the principal asks at quarter end are already answered, with the data set attached.

Why trust a new platform with the family's record?

Because nothing here asks for your trust first. Before you send us anything you get a sealed proof of your own filed book. The controls are checked by machine on a schedule and published with their last result. The guarantees are enforced by writing one line. And the first ten founding clients pay nothing for ninety days, then keep their price for thirty-six months.

What does it deliberately not do?

It does not estimate what a public filing returned. The cohort work is holdings facts only: how many names carry a book, what share sits in the ten largest, what was added and let go. Returns would need a market-data licence we do not hold. A number we cannot check does not go on a page. It does not need a live feed to start. The book loads from the exports your custodian, platform or accountant already produces, which is also the version your auditor can follow. Direct bank and custodian connections are built and switch on per client. It brings no index data with it. Comparisons run against the series the client licenses or supplies. The series in the demo are invented, labelled as invented, and the system refuses to attach them to a real client's report. It will not give you an opinion. It computes and records. The hurdle, the reserve, the benchmark and the buckets are the client's and its advisers'; the decision is the trustees' or the principals'. Nothing here is investment advice. It will not guess. Until the figures an answer rests on are on the ledger with a source and an approver, it names the missing input and waits. Once your policy numbers are signed, it answers, and the answer can be checked.

How much of my time does onboarding take?

About two hours across the four steps that are yours: the profile, the NDA and order form, the entity list (usually with your CPA), and two calls. Custodian paperwork is ours to chase.
