Conclusion
The insurance consulting market in 2025 is bifurcated into two main camps: the Strategic Visionaries (MBB and Big Four) who define where the industry is going, and the Technical Executioners (Accenture, LTIMindtree, Cognizant) who build the engines that get them there. For an insurance carrier, the “top” firm depends entirely on whether they need to solve a capital crisis, navigate a merger, or undergo a complete AI-driven overhaul.
Market Research Insight: We are seeing a massive shift toward “Niche Specialization.” Firms like Simon-Kucher (Pricing) or ZS (Sales) are often winning projects over larger generalists because of their surgical precision in solving specific ROI-linked problems.
