Counterparty Onboarding

An engagement is either set up to be done right or it is not, and onboarding is where that is decided. The firm treats it as a discipline — orderly, documented, and compliant before any sensitive data moves.

Counterparty Onboarding is how an institution becomes an active counterparty of the firm — the documentation, the vetting, and the steps that take an engagement from agreed to operational. The firm runs it as a discipline, not a formality: contracts and registrations handled properly, mutual diligence done, and the compliance gates set in the right places — including a Business Associate Agreement in place before any protected data moves. The point is an engagement that is sound from the first day, for both parties.

THE PRINCIPLE

Onboarding is where an engagement is made sound.

The terms of an engagement, the protections around its data, and the diligence each party owes the other are not paperwork to clear on the way to the work — they are the work's foundation. The firm treats onboarding accordingly: as the stage where an engagement is set up to be compliant, documented, and sound before anyone relies on it. Done properly, it is invisible later. Done poorly, it is where the problems start.

Set up to be done right.

An engagement carries whatever was built into it at the start. The firm builds in the protections, the documentation, and the diligence — before the work, not after.

THE PROCESS

From agreed to operational.

Engagement terms.
The agreement that defines scope, terms, and the responsibilities of each party — the foundation everything else rests on.
Compliance and data protections.
The compliance gates set before work begins — including a Business Associate Agreement in place before any protected health information or sensitive client data moves, and the data-protection terms that apply, GDPR and UK GDPR among them where European data is involved.
Mutual diligence.
Counterparty diligence in both directions — the firm's review of the counterparty, and the documentation the counterparty needs to complete its own review of the firm.
Activation.
With the agreements and protections in place, the engagement goes operational — under the senior-led delivery and validation discipline that govern the firm's work.
DOCUMENTATION

What the counterparty needs is ready.

An institutional counterparty — a health system, an agency, a prime — arrives with its own diligence requirements, and the firm is built to meet them. The assurance, compliance, and data-protection documentation in the Trust Center exists precisely for this stage: to answer the questions a serious counterparty asks before it signs. The specific onboarding documentation is provided directly, scaled to the engagement.

TO BEGIN

Where onboarding starts.

Onboarding follows a decision to engage — so for an institution already in conversation with the firm, it is the next step, handled directly with the senior team. For an institution not yet in that conversation, it begins one step earlier: at the door. The firm will take it from there, in the right order.

Complexity doesn't wait.

Neither does an institution ready to begin. The firm onboards the way a serious counterparty expects — properly, and in the right order.
