Paritee accelerates U.S. expansion and bolsters corporate advisory capabilities with acquisition of One Strategy Group

Oslo / New York, February 26, 2026 – Paritee, the fast-growing international communications and advisory firm, has acquired One Strategy Group, a corporate strategy and executive communications firm. The move expands Paritee’s footprint in the United States and adds to its senior-level corporate and C-suite advisory capabilities.

Founded in 2023, One Strategy Group advises CEOs and C‑suite leaders with specialist expertise in corporate positioning, reputation strategy, media relations, and executive communications. The firm has more than 20 professionals across New York City and Washington, D.C., and is recognized for helping clients navigate societal complexity, anticipate risk, and align business strategy with clear, credible, and compelling external narratives.

The acquisition initiates a new growth platform, focused on corporate advisory services, alongside Paritee’s existing U.S. presence through Brands2Life, the integrated communications agency known for its deep expertise in the tech industry. Under the leadership of CEO David Meadvin, One Strategy Group has experienced rapid growth and built a strong reputation advising large public companies as well as high-growth startups. 

“We are delighted to welcome One Strategy Group to Paritee,” said Lars Erik Grønntun, Founder and Executive Chairman of Paritee. “David and his team bring extensive experience advising CEOs and leadership teams at pivotal moments, giving us a strong new platform for growth in the U.S. and enhancing our existing capabilities in the American market. Looking ahead to Paritee’s next development cycle, the U.S. will be a prioritized growth market for Paritee.”

“We built One Strategy Group to serve leaders facing complex strategic decisions,” said David Meadvin, CEO of One Strategy Group. “Joining Paritee gives us broader international reach and access to a strong network of advisory firms while maintaining the focus and culture that define our team.”

The One Strategy Group leadership team also includes Everett Rosenfeld, Executive Vice President and Co-Founder; Elizabeth Stein, Managing Director; and Sophie Ross, Executive Vice President.

As part of the transaction, One Strategy Group CEO David Meadvin becomes a Partner in Paritee and assumes the role of President of Paritee Holding U.S., with a mandate to drive further growth and expand the company’s advisory services in the United States. He will work closely with Rene Musech, Paritee Partner and President of Brands2Life Holding U.S. who will continue to lead Brands2Life’s U.S. operations and further expand its strong position supporting technology clients navigating U.S. market expansion, category leadership, and IPO readiness.

“With One Strategy Group, we add further depth in senior corporate and executive advisory,” said Jonas Palmqvist, CEO of Paritee. “Alongside Brands2Life in the U.S., we now operate two complementary advisory businesses with distinct strengths and shared ambition.”

The acquisition follows Paritee’s recent expansion across Europe and the Middle East, including investments in Truth Consulting, Kruse Larsen, North Seventy Five, Fenton Fitzwilliam and RPP Group. Paritee currently operates across nearly 20 offices in 12 markets, advising clients across technology, healthcare, energy, financial services and other regulated industries.
