BCG X vs Sia Partners: overview
BCG X
BCG X launched in 2022, when Boston Consulting Group merged BCG Digital Ventures, BCG Gamma, and BCG Platinion into one unit. Job listings put it at 3,000+ technologists, data scientists, engineers, and designers in more than 80 cities (per company job postings; independently unverifiable). The difference from a pure strategy team is timing. Prototypes get built during planning, so a board can see a working version before it approves the full program. BCG's industry practices and change work back it up, and its fees match BCG's, which keeps most mid-market companies out.
Sia Partners
Sia Partners was founded in Paris in 1999 and employs about 3,500 consultants in roughly 48 offices across 20 countries. It calls itself a "Consulting 4.0" firm and pairs advisory work with Heka.ai, its own catalog of AI software products. AI strategy and governance are strongest in energy, utilities, and financial services, where the firm has long-running regulatory practices. What a buyer gets is a management consultancy that can show early value with ready-made tools.
