Corporate Governance & Compliance
Designing governance architectures and compliance frameworks that embed accountability at every level of the organisation.

Strategic Advisor & Executive Director
Strategic advisor and director in governance, risk, and long-term strategy.
Antonina Lagun is a Strategic Advisor and Executive Director who counsels boards and leadership teams on the disciplines that define durable institutional success: corporate governance, enterprise risk, and long-term strategic direction. Her practice centres on translating complexity into clarity, helping organisations structure their oversight responsibilities, align executive decision-making, and build resilient operating models that withstand scrutiny and volatility alike.
Across engagements, Antonina operates at the intersection of strategy and stewardship. She advises on governance architecture, board composition and effectiveness, and the frameworks required to manage financial and operational risk with precision and restraint. She equips executives and directors with the judgement, structure, and discipline to lead with confidence through periods of growth, transition, and uncertainty. Antonina also serves on boards and is available for non-executive and executive director appointments, alongside her advisory work.
Known for a measured, principle-driven presence, Antonina is sought for her ability to distil complex regulatory and financial landscapes into clear, actionable counsel. She brings a rigorous, evidence-based mindset to every mandate, and a conviction that exceptional governance is not a compliance obligation but the foundation of enduring enterprise value.
