What does it take to build a consulting firm that is global from day one?
In this episode, Joe O’Mahoney speaks with Matthieu Courtecuisse, Founder & CEO of Sia, about the long-term decisions behind building one of the world’s largest founder-led consulting firms.

Matthieu shares how Sia was built with international scale in mind from the very beginning, why founder commitment matters more than capital in global expansion, and how early investments in data, AI, and technology shaped the firm’s competitive advantage. He explains Sia’s augmented consulting model, where proprietary platforms and AI tools sit at the core of delivery—not as add-ons.

The conversation also covers Sia’s approach to growth through selective acquisitions, the balance between building and buying capabilities, and how culture-led integration supports scale. Joe and Matthieu close by discussing how AI is reshaping consulting economics, talent models, and why firms need to think in decades, not quarters, when building lasting value.

In this episode you will learn:

• Why Sia was built with global scale as a core ambition
• How founder commitment drives successful international expansion
• Why early investment in AI and data created long-term advantage
• What augmented consulting looks like in practice
• How Sia approaches M&A without diluting culture
• Why consulting firms must think long-term to build real value

This episode offers a long-term view on what it takes to build a global consulting platform—through sustained investment, founder leadership, and a clear belief in technology as a driver of scale and value.

What does leadership really look like when growth, pressure, and personal risk collide?
In this episode, Joe O’Mahoney speaks with Richard Goold about scaling consulting firms, leading under strain, and building long-term value without losing culture.

Richard Goold supports founders, CEOs, and boards through the hardest stages of growth—scaling sustainably, protecting culture, and preparing for long-term value creation. He has led and exited consulting businesses, including a £35m sale following an MBO, and now advises fast-growth firms across the UK and US. Earlier in his career, Richard also served as a frontline Met Police officer, an experience that deeply shaped his views on leadership, trust, and decision-making under pressure.

Richard shares his journey from big consulting firms to leading Moorehouse through an MBO, growing the business from £3m to £35m, and ultimately selling it. He reflects on the realities of leadership during high-stakes moments, including remortgaging personal assets, navigating near-deal failures, and carrying responsibility for people as the firm scaled.

The conversation explores what truly drives firm value beyond revenue—succession planning, client concentration, codifying knowledge, and leadership depth—as well as why these factors must be addressed years before an exit process begins.

Joe and Richard close by discussing today’s consulting landscape, including the cultural challenges of remote work, the risks and opportunities of AI, and what leaders must do now to stay relevant and protect enterprise value.

In this episode you will learn:

What does it take to scale a consulting firm internationally without external capital?
In this episode, Joe O’Mahoney speaks with Olly Purnell, Managing Partner and co-founder of Q5, about how the firm grew from a five-person partnership to a global consultancy. With nearly 30 years of consulting experience, he leads client engagements across sectors while also focusing on attracting top talent to support Q5’s growth in the UK, US, and Australia.

Olly explains why Q5 moved away from an associate-heavy model, how they built a culture around organisational health, and how their internal tool—Org Maps—supports operating model work by analysing spans, layers, and resource allocation directly from client ERP data.

They also discuss Q5’s shift from a traditional partnership to a broader shareholder structure, the targeted mergers that helped them enter new markets, and the leadership decisions that preserved the team during COVID-19.

Olly closes with insights into the future of consulting, the impact of AI, and Q5’s focus on strengthening their tools and international footprint.

In this episode, you will learn:

• How Q5 scaled from a small founding team to an international consultancy
• Why the firm shifted from an associate-led model to full-time hiring
• What “organisational health” means in practice and how Q5 delivers it
• How Org Maps supports operating model and workforce decisions
• Why Q5 moved from a partnership to a broader shareholder structure
• The leadership decision that protected the firm during COVID-19
• How Q5 approaches growth, culture, and the future of consulting in an AI-driven era

This conversation offers a clear look into how Q5 has grown, adapted, and defined its approach to organisational health. Olly’s reflections on culture, structure, and leadership provide practical insights for any consultancy thinking about scale. We hope you found the discussion valuable and thought-provoking.
