Management advisory for high-performance organisations
Olga Nissen, Management consultant.
Where my curiosity runs deep
Large scale transformation
Value creation plan
Strategy
Due diligence
Digital strategy
With +20 years of experience in strategy, transformation, and leadership advisory, I work closely with CEOs, executive teams, and private equity firms to drive meaningful value creation and sustainable growth.
Having led complex transformations at Tryg, advised global clients as a Partner at McKinsey, and held senior roles at Accenture, I bring a pragmatic, insight-driven approach grounded in business impact.
I combine proprietary playbooks, proven frameworks, and a 360-degree view of business, culture, and market trends to deliver clear, actionable strategies that align leadership and accelerate execution.
My Approach
“Olga quickly made an assessment of the AS-IS situation of the IT setup of the company. She involved key stakeholders, held workshops and within a very short period, she managed to map the status and come up with a clear hands-on roadmap how to improve the setup. Most impressively, she engaged strongly with the CIO and key stakeholders in way where they took on the full ownership of implementing the plan. She gave us exactly the clarity we needed, which ultimately accelerated the needed transformation. It was great!”
- Group COO & Boardmember, Sun European Partners
