Service Architecture

Strategic Governance as a Service

Four tiers structured as a progression from initial assessment to deep, board-level governance partnership. Every engagement deploys the Adversarial Methodology, calibrated to the tier.

A Continuous, Cumulative Governance Partnership.

Traditional governance advisory is episodic. A firm engages a consultant, receives a report, and manages governance internally until the next incident triggers the next engagement. Institutional knowledge is lost between engagements.

SGaaS is structured as a continuous, principal-led function delivered on a retainer architecture. It complements internal audit, risk, and compliance, and provides the adversarial challenge the Three Lines Model was never designed to deliver.

The four tiers are designed as a progression. The Diagnostic builds the institutional knowledge that makes the Retained tier effective; the Retained tier creates the conditions under which Embedded becomes a natural evolution; the Pre-Exit tier turns governance maturity into a defended exit valuation.

Embedded SGaaS

Permanent Board-Level Challenge Function

The Embedded tier provides everything in the Retained tier, plus permanent board-level presence. The SGaaS principal attends board and committee meetings as a contracted Independent Board Observer (or Mandated Advisor to the Risk or Audit Committee) with contractual challenge authority. The principal does not vote and owes no fiduciary duties, a deliberate architectural choice that preserves the independence on which the challenge function depends.

Pre-Exit SGaaS

Exit-Aligned Governance

Pre-VDD governance remediation for PE portfolio companies in the 12–18 months before a sale, IPO, or other liquidity event. We remove the governance and capital-discipline gaps a buyer's diligence team would use to chip the price, before due diligence begins. The engagement delivers an MRMM-scored maturity diagnostic, prioritised remediation, a buyer-ready data room, and an internal Board Assurance Ledger, defending the headline price through exclusivity.
