WORK HISTORY
Founder & Principal Advisor @Isometri
ISOMETRI is a governance architecture advisory firm that enables sustainable growth by building oversight infrastructure that protects trust, strengthens credibility, and reduces existential risk.I work with organisations operating in high-trust, high-consequence environments, including businesses handling client funds, sensitive data, public funding, regulated activity, and reputation-dependent services.My work is delivered through structured governance transformation engagements, typically involving: • enterprise-wide organisational and governance identification • design of minimum-viable governance architecture • leadership facilitation and behavioural transition • operational embedding of governance systems • verification and assurance strengtheningISOMETRI’s philosophy is that governance should be operable, commercially grounded, and sequenced to the organisation’s growth stage. Effective governance protects trust while enabling growth, rather than slowing it.

ABOUT JONATHAN MAIN
Most organisations do not fail because leadership lacked effort, intelligence, or intent. They fail because responsibility expands faster than oversight; and informal control does not scale. Performance can remain strong while structural exposure quietly accumulates. I work with founders, CEOs, boards, and investors in organisations where trust, delegated authority, funding, or public credibility must withstand scrutiny. These are typically high-performing businesses that grew through founder oversight, strong culture, and capable teams - and are now approaching a structural transition. Leadership recognises it first. It often appears as: • increasing cognitive load • decision bottlenecks • reliance on institutional memory • uncertainty about whether critical risks are genuinely visible This is the point where governance stops being administrative and becomes existential. I design and embed governance architecture that converts leadership-dependent control into scalable institutional oversight. The objective is not bureaucracy. It is sustainable growth under scrutiny. My work typically involves: • exposing structural fragility hidden behind performance • designing mission-aligned governance architecture • embedding accountability, risk visibility, and assurance • supporting the leadership transition from control to oversight • removing unnecessary controls while strengthening critical ones Increasingly, this transition is triggered by formal regulatory accountability: including NIS2, the Cyber Resilience Act, and emerging EU AI governance requirements. In these situations, leadership is not asking how to implement controls. They are asking: • Who is legally accountable? • How is oversight structured at executive level? • Would our escalation and incident visibility withstand regulatory scrutiny? I provide structured governance reviews that clarify director accountability, escalation design, and oversight exposure before implementation discussions begin. I work directly with senior leadership through structured, face-to-face governance transformation engagements. I am not a compliance implementer, audit substitute, policy writer, or framework reseller. Certification and assurance outcomes often follow the work but they are consequences of governance maturity, not objectives. If organisational performance still depends on leadership vigilance to maintain standards, structural exposure is already present.
