DAP Compiler

Plane 01

Classification. The DAP Standard.

One shared way of describing every holding, built around a single question: where does the money actually come from. Policy and research both use it, so a term means the same thing in both.

StatusIn use

Depends onNothing. Everything else is built on it.

Consumed byPolicy, Research, Attestation

Always trueNo holding is reduced to a single score.

Where the money comes from, not what it is called

Two holdings can sit in the same legal wrapper and make money in completely different ways. Two that look unrelated can make it the same way. The Standard sorts holdings on that basis, because that is the level at which exposure, concentration and mandate questions are actually asked.

No single score

A holding is described in layers, not collapsed into one number. A single score would throw away the detail that policy and research need, so we do not produce one.

Why it comes first

Because policy and research use the same definitions, nothing further down the line has to reconcile two versions of the same holding. Every record names the Standard alongside the policy version it applied.

Plane 02

Policy.

Your written policy becomes the working rules. Mandates, limits and exclusions turn into checks that run at the moment a decision is made, not in a review months later.

StatusIn use

Built onClassification

ProducesWorking rules that run at the moment of decision

Always trueA rule must be approved by a person before the system will use it.

Every rule carries its paperwork

Each rule records where it came from, which version it is, the date it takes effect and where it applies, and a person has to approve it before the system will use it. When two rules conflict, the system says so instead of quietly picking one.

What happens when a rule changes

The change is pulled out of the document, turned into working rules, and run alongside the live ones so the difference is visible before it counts. A named person signs it off, then it switches on. Until it is signed it does nothing. No software release, and no rewriting the document.

Where the rules actually run

Overture runs the day to day. It checks each decision against the rules, sends it where it needs to go, and writes the record. Antechamber is the sealed test area where anything new is tried before it touches live work. Both read the same rules rather than keeping their own copy.

Change states proposed · approved · in force · still reversible during the review window

Plane 03

Research. The Institutional Research Operating System.

Every measure has a dated version, so any number can be reproduced later. Ideas and assumptions are labelled proposed, approved or passed on. Nothing becomes final until a person approves it.

StatusIn use

Built onClassification

ProducesDated versions of every measure

Always trueA model can suggest. Only a person approves.

Ask any question as of any date

Every measure records the date it took effect, and every result records which versions produced it. You can ask a question as of a past date and get the answer as it stood then, so a figure published last year can be reproduced exactly.

Changes are visible as changes

When a measure is revised, older work does not quietly change meaning. The revision shows up as a revision. That is the difference between a research record and a spreadsheet.

Gaps are shown, not filled

If something has not been approved, it says so. If a number is missing, it says so. Nothing is filled in, smoothed over or guessed, because a gap is itself something a committee needs to see.

Object states proposed · approved · passed on

Plane 04

Attestation.

Every decision that matters is written into a signed record you can hand to someone else. They can check it on their own computer, with no access to our systems and no need to take our word for it.

StatusIn use

UsesApproved policy and approved measures

ProducesSigned decision records

Always trueOnly deterministic evaluation over ratified inputs may be attested.

What is in a record

The decision, the policy version, the exact clause, the versions of every measure used, who signed it and when. Records are linked to each other, so if anything is altered later it shows.

Why the check never varies

A record is only worth something if someone else can run it again and get the same answer. That is why the check is a fixed calculation over approved inputs, and why no AI model sits anywhere in this path.

It can run entirely inside your walls

The Compiler runs inside whatever boundary you set, disconnected from the internet if that is the requirement. The records and the tool that checks them travel as files, so nobody needs access to a service to verify anything.

Each record holds the decision · the policy version · the exact clause · the measure versions · who signed · when

Who we serve

Institutions that have to prove it.

Pensions and institutional asset owners. Alternative investment firms and asset managers. Family offices. Sovereign and large institutional allocators.

Pensions and institutional asset owners

The investment policy, including the rules that differ by jurisdiction and who is allowed to decide what, is checked at every allocation. The evidence is produced along the way, instead of being assembled after someone asks for it.

Alternative investment firms and asset managers

Each client's mandate becomes checks on that account, so a limit is caught while the order is being formed. Due diligence questions get answered from the record.

Family offices

Several entities and several managers under one policy, checked continuously, so quarter end is a review of the exceptions rather than a reconciliation.

Sovereign and large institutional allocators

The Compiler runs inside the boundary you set, with data residency and offline running built in rather than added on.

How institutions use it

What the institution holds afterwards.

Short examples. Each one ends with what the institution is left holding: a record it can prove.

CASE 01

Canadian pension plan

One investment policy, including the rules that differ by jurisdiction and the threshold above which the board must be told, turned into checks that run at every allocation.

Holds: a signed record for every allocation, naming the policy version and the exact clause behind it, which can be handed to the regulator without us being involved.

CASE 02

US family office

Several entities and several managers under one family policy, with exclusions and concentration limits checked as they go.

Holds: a running list of exceptions, by entity and by manager, that lines up with the policy version in force on the day of each trade.

CASE 03

Sovereign fund

A hard boundary, with the rules, the decision records and the full history staying inside it, and offline running supported by design.

Holds: a complete chain of records that never left the building and can be checked with no internet connection.

CASE 04

Asset manager

Each client's mandate becomes checks on that account, so the limit is there when the order is being formed.

Holds: proof, account by account, that every order was checked against the terms in force at the time, so a due diligence questionnaire is answered from the record.

About the founder

Brendan Sibeth.

Founder and managing partner of Dartmouth Advisory Partners, which he established in Toronto in January 2025. He spent roughly thirteen years in institutional investment technology and quantitative data analytics, in senior roles at MSCI Burgiss and SS&C GlobeOp, with earlier work at TD Bank and Green Street.

Why the firm is built this way

He has worked with the systems institutions already run, including BlackRock Aladdin, MSCI BarraOne, MSCI Total Plan, MSCI RiskMetrics and the SS&C suite. The Compiler is built to sit alongside that stack rather than replace it, and classification comes first because that is where most of the wasted reconciliation effort happens.

Readiness assessment, or direct engagement.

A fixed-scope review you can take to your board. It establishes where AI is already being used across the firm, approved or not, what an examiner would find today, and which workflows are worth doing first.

Direct engagement

One senior person owning your AI agenda, working inside your team, carrying the work from the first question through to a running system and then handing you the capability. The rules, the audit history and the setup are yours, in open formats, permanently. We take on a small number of clients at a time.
