Andersen Expands Strategy, Innovation & Growth Capabilities with Acquisition of Endeavor Management and Clareo

Acquisition Strengthens Andersen’s Ability to Help Clients Accelerate Profitable Growth, Improve Performance and Create Long-Term Enterprise Value

Endeavor Management and Clareo proudly announce they have been acquired by Andersen Group Inc. (NYSE: ANDG), expanding Andersen’s consulting platform with enhanced capabilities in strategy, innovation, growth and enterprise performance. The transaction also includes RTRN Strategy, a full-service embedded advertising agency acquired by Endeavor Management in 2021. Prior to the acquisition by Andersen Group, Endeavor combined with strategy and innovation consultancy Clareo, creating an integrated advisory team that helps organizations identify new growth opportunities, strengthen competitive position, improve profitability, and execute strategic initiatives that deliver measurable business value.
Andersen Group’s acquisition of these complementary groups supports its continued expansion as a multidimensional professional services platform and broadens its presence in high-value strategic advisory services. The combined team integrates corporate strategy, innovation, customer and market strategy, brand and creative services, strategic communications, enterprise transformation and value realization into a coordinated client offering. Endeavor, Clareo and RTRN Strategy will transition to the Andersen Consulting brand in the coming months.

“Joining Andersen represents an important step in Endeavor’s continued evolution as a strategy and growth advisory firm,” said Bill Nash, Founder and CEO of Endeavor Management. “Clients increasingly seek integrated advisors who can help them identify new opportunities, accelerate profitable growth and successfully execute strategic initiatives. As part of the Andersen platform, we can deliver those capabilities at global scale, while creating meaningful opportunities to collaborate across Andersen’s global multidisciplinary platform.”

The combined team’s capabilities include:

Together, these capabilities enable Andersen to support clients across the full growth and performance lifecycle—from identifying opportunities and shaping strategy through market activation, organizational execution and measurable value creation.

These acquisitions also expand opportunities to combine these capabilities with Andersen’s existing consulting, tax, legal, valuation, and global mobility services. This integrated approach allows Andersen to address strategic, financial, operational, and regulatory challenges through coordinated multidisciplinary teams while deepening client relationships and creating additional cross-service opportunities.

“Our focus has always been helping organizations convert strategic ambition into measurable business performance,” said Allan Platt, Clareo CEO “Joining Andersen, along with Endeavor and RTRN Strategy, allows us to combine our expertise in strategy, innovation, market growth and execution with Andersen’s global platform and multidimensional capabilities. Together, we can help clients accelerate revenue growth, improve profitability, and create sustainable enterprise value.”

The combined team serves clients across industries including energy, healthcare, life sciences, industrial markets, financial services, and the public sector. Its professionals advise organizations on growth strategy, innovation, customer experience, market positioning, enterprise performance, and strategic execution.

By expanding its strategy, innovation, and growth capabilities, Andersen continues to invest in services that help clients identify new opportunities, improve enterprise performance, and create sustainable long-term value.
