About

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.

Sift Healthcare

Sift Healthcare is a healthcare payments intelligence company leveraging data science and AI to optimize revenue cycle performance for healthcare providers. Founded in 2017 and based in Milwaukee, Wisconsin, Sift's flagship product RevProtect delivers payment intelligence that predicts, prevents, and resolves reimbursement risk for health systems. The platform connects clinical context and payer response patterns to predict reimbursement risk in real time, then delivers that intelligence as clear, role-specific actions embedded directly into existing workflows across Utilization Review, Clinical Documentation Improvement, Coding, and Patient Financial Services. Health systems face mounting challenges as payers increasingly use AI to scrutinize documentation and downgrade claims, with denials persisting around 15% despite waves of supposed AI solutions. Sift addresses this gap by providing real-time predictions that tell revenue cycle teams what will happen before claims go out the door and what to do about it. The company has analyzed millions of claims, built 329 proprietary MS-DRG playbooks, and delivered measurable impact for health systems managing complex payer mixes. Their intelligence is deployed across 88 health systems, with real-world results including $77M in avoidable writeoffs identified for a $9B health system, $7.6M in additional revenue captured at a $5B regional health system, and $80M midcycle prevention opportunity flagged at a $9B health system.
