Key points of this article
- AI consulting firms fall into five kinds: strategy firms, the Big Four, IT-services integrators, deployment firms tied to AI labs, and boutiques and solo consultants. Each describes what it sells and how it works differently.
- None of the firm pages we read states what an engagement costs. The contract type decides who carries cost risk: the US acquisition rules say time-and-materials gives the contractor no built-in incentive to control costs, while firm-fixed-price puts that risk on the contractor.
- In MIT Project NANDA's preliminary 2025 sample of 52 organizations, external partnerships with customized, learning-capable tools reached deployment about 67% of the time against about 33% for internally built tools, but the authors say the gap may reflect the organizations, not the approach.
- Several specialist firms changed hands in 2026: Fractional AI is now Ode, Ode bought Casper Studios, and the OpenAI Deployment Company bought Tomoro and agreed in July to buy Northslope, subject to closing conditions. Ask who owns a firm today.
