Expertise

Successful leaders don’t just adapt to complexity — they shape it. Today, targeting positive returns isn’t enough; executing your strategy is paramount. This demands ruthless prioritisation: knowing what to focus on and what to not, to deliver the right things faster. Transformation thrives where this style of courage meets clarity.

Oli joined Analysys Mason as a Partner in 2025. Oli’s career began as a Design Engineer working across Toyota’s new vehicle production lines, sparking his passion for operational excellence. There he led teams in Japan and the UK, focusing on innovative process design. When your production line delivers a car every 54 seconds, the sheer power of process becomes clear – as does the balance between standardisation and agility, to drive customer value. 

More than two decades later, Oli’s experience spans many industries, from technology to telecoms and consumer products to pharmaceuticals, through to private equity, financial services and the health sector. He has worked in-house as well as providing expert client-side advisory services. His expertise varies from partnering with clients to reduce their cost base, re-designing their operating model to better serve their customers, shaping and delivering transformation programmes to deliver bottom-line benefits, and implementing synergies post-merger or acquisition.

People who have worked with Oli commend his hands-on approach, his commitment to collaboration and his ability to support, stretch, coach and empower in equal measure. Central to his professional ethos is his service to his clients, nurturing healthy teams, and sponsoring diversity, equity and inclusion (DE&I). Oli is committed to promoting belonging, purpose and wellbeing, helping ignite creativity and advancement for all.

Outside of his professional life, Oli is a mentor for the Association of Tennis Professionals (ATP) Tour. He supports active professional tennis players and helps them to use their talents such as discipline, excellence and commitment in their post-playing career. He is also a leading voice in online and offline channels on neurodiversity and diversity of thought and promotes a deeper understanding of challenges faced by different groups in our societies.
