Strategic Governance as a Service
We Simulate Failure So Leaders Don't Have to Experience It.
Principal-led governance advisory helping organisations achieve their objectives through constructive challenge.
The Marentis Labs Difference
Adversarial Analysis
Our Red Team approach subjects every governance assumption to rigorous, dispassionate challenge, revealing hidden fragilities before they surface in a boardroom or regulator examination.
Financial Services Rigour
Governance frameworks refined by Tier 1 Global Investment Banks now available to boards across every sector. Twenty years of world-class delivery, not generic consulting methodology.
Principal-Led Engagement
Clients receive board-level CRO expertise directly, with no handoff to junior teams. Our approach is not a traditional leveraged consulting model.
Service Architecture
Strategic Governance as a Service
Four engagement configurations designed around the depth of governance challenge your organisation faces. Every tier embeds our adversarial methodology as standard.
Diagnostic GaaS
Governance Health Check
Point-in-time assessment of governance and risk maturity. The entry point to the Strategic GaaS model: structured, adversarial, board-ready.
Retained GaaS
Continuous Fractional CRO
Ongoing principal-level governance counsel. 15–30 hours per month of continuous oversight, regulatory intelligence, and adversarial challenge. The core revenue relationship.
Embedded GaaS
Principal-Level Governance Ownership
Board seat or risk committee chair. Owen owns the governance framework, manages regulatory liaison, and chairs the challenge function as a permanent embedded resource.
Pre-Exit GaaS
Exit-Aligned Governance
Specialised governance uplift for PE portfolio companies within 12–18 months of exit. Structured to make governance a positive exit narrative, not a diligence liability.
