In 1999, Matthieu Courtecuisse founded Sia with a vision that would redefine management consulting for the digital age. While traditional consulting firms were built on legacy models, Sia was 'born digital' - a deliberate choice to create a new kind of consulting group that could help organizations navigate unprecedented technological change. From its origins in France, the company recognized early on that the digital revolution would require more than just strategy; it would demand a fundamental rethinking of how businesses transform. Over the past two decades, Sia has evolved into a global force with 3,000 consultants across 48 offices in 19 countries, pioneering what they call 'Consulting 4.0' - an approach that augments traditional consulting with data science, creativity, and artificial intelligence.
Today, Sia's mission has crystallized around being 'optimists for change,' reflecting their core belief that successful transformation requires both technical expertise and a fundamentally positive outlook on what businesses can achieve. The firm's comprehensive ecosystem includes strategy and management consulting, AI solutions through Heka, experience design via SiaXperience, specialized life sciences consulting through Sia/LBG, and leadership coaching through Uside. Their 'Consulting for Good' initiative demonstrates a commitment to being purpose-driven, integrating corporate social responsibility across climate, social responsibility, and ethics. With approximately 1,000 blue-chip and big tech clients, Sia continues to prove that a consultancy born in the digital era can deliver superior value while helping clients not just navigate change, but benefit from it.
