Mathieu S.

I work as a fractional CEO and COO for small to mid-market companies, mostly in tech and tech-adjacent services. I come in to build the operating side of a growing business and to help leaders put AI to work in ways that actually move the company, then stay hands-on to get it done.

• Build the structure, processes, and systems that let a business scale without breaking, and reduce its dependence on the founder
• Map how work actually gets done across functions like finance, operations, IT, and customer service, then redesign the parts that slow growth down
• Help teams adopt AI in practical ways, from the tools they use day to day to the rules that keep data safe as usage spreads
• Act as a thought partner on operations, growth, and where AI fits, and own the rollout rather than handing over a plan and walking away
