Sia was born digital in 1999 and has grown into a global management consulting group with 3,000 professionals operating from 48 offices in 19 countries. We work with blue-chip corporations and public-sector organisations to guide strategy, business transformation, and digital innovation. In December 2024, Blackstone acquired a minority stake in Sia, underscoring our standing as one of the industry's fastest-growing consulting groups. In January 2025, we evolved our identity from Sia Partners to Sia — a signal of our ambition for the next chapter.

We are consultants, data scientists, designers, and engineers who share one conviction: optimism is a force multiplier. We believe transformation should generate positive impact — for our clients, their people, and the planet. Our culture celebrates intellectual curiosity, knowledge-sharing, and community. We call it the Sia Village: a global network of colleagues who challenge one another, raise the bar, and celebrate shared success from Paris to Singapore, New York to Perth.

We help clients initiate, navigate, and benefit from transformation. Our consulting capabilities span corporate strategy, business transformation, modern finance, HR and organisational effectiveness, risk and compliance, cybersecurity, data and artificial intelligence, IT strategy, marketing and customer experience, procurement, operational excellence, actuarial services, and major programme management. We augment every engagement with our proprietary AI ecosystem — Heka — and deploy over 800 AI agents through our Agent Store to accelerate results at scale.

Our mission is to create state-of-the-art narratives for transformation and innovation and deploy them at scale. Our purpose is to achieve transformations that generate a positive impact — for our clients, our people, and the world around us. This purpose animates everything we do, from the strategies we design to the AI solutions we build to the CSR commitments we make through Consulting for Good.

We were born digital — AI and data science are not add-ons for us; they are the operating system of our consulting practice. Our 450+ data scientists and 12 R&D labs produce proprietary tools that accelerate client results in ways traditional consultants cannot. Our global footprint across 19 countries combines local market knowledge with the scale of an international group. We are agnostic on technology but expert in business, and our Consulting for Good approach makes sustainability a lever — not a burden — for our clients. Rated Gold by EcoVadis and ranked in Vault's top consulting firms globally, we deliver results that matter.

We are driven by responsibility, fuelled by creativity, and augmented by data. We believe in the power of optimism to unlock opportunity and mitigate risk. We are committed to diversity, equity, inclusion, and belonging as foundations of a thriving culture. We hold ourselves to uncompromising standards of ethics and compliance — not as constraints, but as a competitive advantage. And we believe that doing good and doing well are not in conflict: sustainability is a lever for profitable transformation.

Consulting for Good is Sia's global ESG approach — integrating environmental, social, and governance commitments into both our own operations and the innovative offerings we deliver to clients. Our three pillars are Climate, Social Responsibility, and Ethics & Compliance. We co-finance the largest mangrove restoration project in Cameroon, targeting 1,000 hectares over 30 years. We achieved carbon neutrality in 2020 and continue our long-term ambition toward net-zero. Our annual Consulting for Good report is published in alignment with GRI standards, and we undergo yearly EcoVadis evaluation — currently placing us in the top 4% of all companies across all industries.

We believe knowledge sharing is the key to innovation and the growth of our people. The Sia Village concept describes our commitment to fostering community within and among our offices. Our office spaces worldwide follow a cohesive design scheme that facilitates teamwork and wellbeing. Annual seminars, cross-office collaborative networks, and sector-focused clubs connect colleagues from every corner of our global footprint. We also engage with local communities through our Consulting for Good initiatives, partnering with non-profits and contributing to public debates as an opinion leader in our markets.

Diversity, equity, inclusion, and belonging (DEIB) are part of Sia's DNA. Our global DEIB@Sia network brings together people worldwide to drive local and global progress. We hold a Gender Equality Index score of 93/100 in France, and we ranked in the top 20 of all Diversity sub-categories in Vault's EMEA and APAC consulting rankings. In our Social Responsibility Lab, we develop offerings that help clients promote diversity and inclusion, including an AI-powered tool that detects gender-coded language in job advertisements and suggests less biased alternatives.
