Arnaud Marlière, Founder @ MCS
With a strong track record in business transformation, growth acceleration, and strategy, I bring a unique blend of experience across startups, scale-ups, private equity-backed enterprises, and large corporate environments. My career spans strategic consulting at BCG, leading growth and GTM strategies in high-growth tech businesses, and successfully scaling and selling a company to a private equity-backed group.
I led all commercial activities—including marketing, sales, BDR, and partnerships—for Awingu, contributing to its successful sale to Alludo, a KKR-backed software group. This experience reflects a balanced approach to managing commercial initiatives and strategic growth.
Having worked at the intersection of strategy, execution, and leadership, I understand what it takes to drive sustainable success. This is why I founded MCS—to help B2B tech companies navigate growth, scale effectively, and unlock their full potential. My hands-on approach ensures that businesses not only define the right strategy but also execute it with precision. Whether it's market expansion, M&A preparation, or commercial transformation, my goal is to enable organizations to grow with confidence and impact.​​​
“Arnaud has a unique background ranging from consulting to scale. What is cool about Arnaud is his ability to shift across multiple functions of the business - sales, marketing, product, etc.. His business acumen is off the charts and has been invaluable to me as a leader. In addition, Arnaud builds followership. His team values his ability to set the north star and share the operational execution so his team feels like they are part of the bigger picture. In FY24, Arnaud was a key contributor to high double digit growth for the fastest growing business. ”
