For forensic & diligence

Completeness on day one. Not week three.

Every engagement is the same completeness rebuild — different target, different stack, same chase. COSai lands you in a completeness package across the target's consented inbox footprint with audit-grade chain of custody, scoped to the diligence period and engagement parameters.

The shape of the gap

A diligence engagement gets handed a target's data room that's curated and partial. The substantive work is everything outside the data room: the receipts that prove the QofE adjustments, the email chains behind the disputed expenses, the supplier correspondence behind the concentration risk, the contract amendments that don't appear in the GL.

The senior associate runs that gathering manually, across whichever inboxes the target's CFO can get consent to share. Three weeks of mid-engagement scramble; some documents never arrive; the final deliverable has caveats tied to documents the team never got to see.

What COSai does mid-engagement

  • Per-engagement tenant. Every diligence target is a separate tenant inside your firm shell — separated data, separated access, separated retention. Wind-down at engagement close runs the documented data-deletion workflow with verifiable receipts.
  • Consent-scoped, every operation. Access requests run only against inboxes the target's consent authorizes. Logged. Auditable. Defensible if challenged.
  • Period + scope, as-of the engagement. The diligence is of the trailing twelve months ending June 30. Every completeness check, every document request, every report runs as-of those parameters.
  • Concentration, dispute, and adjustment surfacing. Transactions with no supporting document, vendors with supplier-correspondence patterns suggesting disputed terms, ledger entries that look adjusted post-period.
  • Deliverable export. The exhibit-ready completeness output formatted for the QofE report or the investigative finding, with the chain-of-custody appendix.

Highest per-engagement value of any buyer we sell to. We engage you after the grant-compliance and mid-size-audit reference logos are landed — security review is real and procurement is long, and we want the references to clear it cleanly.
