Sia is a management consulting group founded in 1999, built on a "born digital" philosophy that places data science and artificial intelligence at the centre of its practice. With approximately 3,000 consultants operating from 48 offices across 19 countries - including its French roots - the firm serves around 1,000 blue-chip and big tech clients. Its approach, branded Consulting 4.0, augments traditional advisory with data science, creativity, and AI to deliver digital transformation at scale.
The firm's capabilities span a range of specialist practices: Heka for AI solutions, SiaXperience for experience design, Sia/LBG for life sciences consulting, and Uside for leadership coaching. Strategy, management consulting, and hands-on implementation run through each of these offerings, reflecting the firm's emphasis on moving from insight to execution.
Sia positions itself as purpose-driven, describing its people as "optimists for change." This ethos extends to Consulting for Good, an initiative that integrates corporate social responsibility across climate, social responsibility, and ethics into the firm's work. The combination of technical depth and a values-led culture is central to how the firm distinguishes itself in a crowded consulting market.
