13 of the 64 AI implementation consultancies that help companies build on AI tracked on AI Implementation Companies are large firms, as of October 14, 2026. The featured partner, asaasin.ai, is pinned first when it qualifies; every other row is alphabetical, unpaid, and drawn from public information.
Large firms in this directory are global consultancies with AI practices inside much bigger organizations, including Thoughtworks, EPAM Systems, and Publicis Sapient. They can staff multi-year programs across several countries and handle procurement, security, and compliance requirements that smaller shops struggle to meet.
The tradeoff is access. On a large engagement you may be one account among many, and the team that pitches is not always the team that delivers. Ask for named delivery leads and a reference client of similar size.
For a narrower scope, look at mid-size firms or boutique studios. Large-organization projects are covered on the enterprise AI page. Use the comparison table and how to choose to weigh options.

It delivers across North America, Europe, and Asia at a scale suited to large, multi-market rollouts rather than a single scoped pilot.

Publicis Sapient is headquartered in Boston and has been operating since 1990 as the digital business transformation arm of Publicis Groupe. What it does: it helps large, often Fortune 500 enterprises modernize legacy technology and adopt AI, across AI strategy, enterprise AI programs, and AI product development, usually inside broader transformation engagements rather than standalone AI projects. Locations and delivery: teams across North America, Europe, Asia, and remote. Best fit: companies that need AI work embedded in a wider modernization program, not a narrow point solution or a fast, small-team build.

Slalom Build is the product engineering arm of Slalom, headquartered in Seattle. It builds custom software and integrates AI for enterprise clients across North America and Europe, with listed work in AI product development, AI strategy, enterprise AI, and AI integration. Because it sits inside a larger consultancy, it can pair a shipped product with Slalom's technology and change-management practices; ask about that directly if your project needs organizational rollout support too.
