History

Foundation and early development (1999–2008)

Sia was co-founded in 1999 in Paris by Matthieu Courtecuisse, initially specializing in the financial services and energy sectors before expanding its expertise to other fields and positioning itself in the adoption of artificial intelligence for businesses[4].

Between 2005 and 2009, Sia expanded its operations in Europe and the Middle East, opening offices in Belgium (Brussels), Italy (Rome and Milan), Morocco (Casablanca), the United Arab Emirates (Dubai), and the Netherlands.

External growth and international expansion (2008–2020)

Starting in 2008, Sia pursued an external growth strategy, primarily through the acquisition of local consulting firms organized around specific markets or areas of expertise.

Between 2008 and 2012, Sia completed two tactical acquisitions in France: EDS Consulting Services France (2008) and Axelboss[5]

Between 2013 and 2018, Sia acquired the international management consulting activities of the Investance Group[6] in London, Hong Kong, and New York. In London, Sia also acquired three boutique firms: Molten Group, Inzenka, and SKT Consulting[7].

In 2017, Sia acquired an investment fund called “Le Studio,” designed to invest in start-ups[8].

Between 2018 and 2020, the firm acquired Loft9 Consulting[9] and Pathfinder.

In 2020, Sia launched a strategic consulting practice dedicated to cybersecurity in Paris.

Consolidation and diversification (2021–2024)

In 2021, Sia surpassed 2,000 employees globally. The company also created SiaXperience, a brand grouping activity related to creativity and design[10].

In 2021, Sia acquired Uside, a French consulting firm specializing in leadership, organizational behavior, and quality of work life, founded by Eric Albert.

Between 2021 and 2023, Sia successively acquired Ethier[11], Summus Group, PPT Consulting, Stratumn[12], E2E"Edmonton-based management consultancy E2E joins Sia Partners". Consulting.ca. 2022-09-12. Retrieved 2026-02-20. Churchill Consulting[13], and Latham BioPharm Group[14].

Blackstone investment

In December 2024, the investment fund Blackstone acquired a minority stake in Sia for an amount of €250 million[19].

Artificial intelligence activities

Since the late 2010s, Sia has integrated artificial intelligence into its consulting activities. The firm reports employing approximately 450 data and AI specialists and operating several international research and development laboratories. According to Consultor.fr, this positioning reflects a broader evolution in industry practices[20]. In 2023, the company introduced a generative artificial intelligence tool called SiaGPT[21].

In 2025, Sia launched an “Agent Store” to offer agent-based solutions to its partners. Sia also established partnerships with AWS[22] and NVIDIA[23].

Commitments and responsibilities

Since 2019, Sia has implemented a corporate social responsibility (CSR) approach, including initiatives related to environmental issues, diversity, and selected innovation projects.

Management

Sia is led by Matthieu Courtecuisse, founder and majority shareholder, and Sandrine Carreau, President and COO. The company’s capital is primarily held by partners and executives, as well as by Blackstone since 2024[24].
