Oliver Wyman has joined Anthropic’s growing roster of professional service partners.

Oliver Wyman is the management consulting arm of Marsh. The latter company, which was until recently known as Marsh McLennan, ranks as the world’s largest insurance broker. It also competes in many other parts of the professional services sector. Marsh’s management consulting revenue segment, which includes Oliver Wyman, generated $1 billion in revenue last quarter. It was also the fastest growing of the company’s core businesses.

Anthropic launched its channel program in March with an initial $100 million investment. Two months later, it introduced a partner track geared towards professional service firms. Participants receive access to go-to-market resources and courses they can use to familiarize their consultants with Claude. The training covers topics such as how to customize the chatbot with plug-ins. After completing a course, consultants receive a certificate that counts towards their employer’s ranking within the Anthropic ecosystem.

Oliver Wyman has joined the AI vendor’s partner program as a Select partner. Anthropic confers that status upon consulting firms with at least 10 employees who possess Claude certifications. Additionally, a company must demonstrate that it has deployed Claude in production for at least two customers over the past 12 months. One of those customers must have a publicly available case study.

“Joining the Claude Partner Network gives us another powerful way to help clients move from identifying high-value opportunities to deploying AI responsibly and at scale,” Johaan Wiggins, the global head of partnerships at Oliver Wyman, told Boardroom Insight. “More broadly, it reflects how we think about our partnership ecosystem: bringing together the right technology and expertise around our clients’ most important challenges, so they can move faster while making thoughtful choices about where and how AI creates lasting advantage.”

Oliver Wyman is not new to generative AI. The firm made its first major foray into the market in 2024 when it introduced an AI consulting offering called Quotient. At the time of its launch, Quotient was supported by about 300 professionals. Oliver Wyman’s AI business has grown quite a bit since then: The Marsh unit says that it has advised clients on “more than $50 billion in AI-related capital deployment” to date.

“No single advisor can credibly bring every capability required for enterprise-scale AI transformation,” Wiggins told us. “The strongest outcomes will come from combining frontier technology with deep industry domain expertise, strategic judgment, implementation capabilities, and probably most importantly an understanding of how specific organizations actually operate. Our relationship with Anthropic amongst others reflects that approach.”

Oliver Wyman is not limiting its AI strategy to a single technology partner. The firm also works with Google Cloud, Microsoft and other key players in the AI ecosystem, some of whom offer in-house LLMs that compete with Claude. That kind of cross-vendor expertise is important because enterprise AI projects usually incorporate technologies from a large number of providers. 

“The conversation is shifting from experimentation to execution at scale — how companies embed AI into critical workflows, scale it across the organization, and ultimately translate the capability of AI into measurable business value,” Wiggins said. “This is where we see partnerships as increasingly important in how we continue to serve our clients.”
