Martyn’s mentoring focuses on the full journey of scaling – revenues, profitability, valuations and personal impact. He works closely with leaders to sharpen their vision, challenge assumptions, and structure practical plans that can be executed at pace. Equally, he supports them in managing investor and shareholder relationships, maintaining market-leading positions and navigating the personal pressures that come with building and transforming organisations. Many of his clients credit him with helping them achieve step-changes in performance while staying aligned to their values and long-term goals.

As founder and CEO of Coffee Nation, Martyn built one of the UK’s most successful consumer product businesses of the last 25 years, creating a new category by bringing premium quality self-serve takeaway coffee to the convenience retail sector. With full strategic and P&L responsibility for 12 years, he grew the business to 600 locations in the UK and Europe, delivered one of the fastest-growing companies in the UK on multiple occasions and secured a 4x return for PE investors. The business was subsequently acquired by Whitbread, rebranded as Costa Express and now operates from around 12,000 locations; by the time of the sale he led, Coffee Nation had served over 100 million customers and remained the undisputed category leader.

Alongside his mentoring, Martyn is an experienced chair, known for establishing high-performance cultures through clear purpose, vision and values and by building highly effective boards. He is a successful business author, a regular keynote speaker on high-growth organisations and has been widely featured in business and entrepreneurship publications. He has contributed to national scale-up reports and served as a judge for major business awards.

Martyn was invited to join the Young Presidents’ Organisation prior to the sale of Coffee Nation and has completed Presidents’ Programmes at Harvard and London Business School, holding roles such as Education Officer and Chapter Chair in London. He is passionate about authenticity in leadership and speaks openly about workplace diversity, using his own experience as a bisexual man in business to encourage leaders to create cultures where people can bring their whole selves to work and tap into their often hidden powers
