US-based consulting firm Protiviti has acquired France-based Adamantia in a strategic transaction that strengthens the financial service capabilities of both firms.

The acquisition will use Adamantia’s expertise in the financial services sector and Protiviti’s expansive global network to create a platform for expansion in the French market.

It follows a two-year collaboration between the two firms, where Adamantia worked with Protiviti clients in financial services, risk, compliance, and internal audit.

Adamantia also accessed talent through Protiviti and its parent company, Robert Half, a global talent solutions organisation.

Protiviti president and CEO Joseph Tarantino said: “The acquisition of Adamantia is strategically designed to help Protiviti better serve its clients in France and globally.

“Adamantia’s experience and deep client connections position us well to further expand our footprint in France’s financial services market.

“Our earlier collaborations with Adamantia have shown that the two organisations have shared values and similar corporate cultures, which is critical to ongoing success.”

Adamantia said the acquisition will enhance its expertise, combine business knowledge, consulting know-how, and strong human values to drive successful client transformations.

Protiviti’s model, which leverages Robert Half’s capabilities to scale teams quickly in response to client needs, will be crucial in ensuring the success of this new chapter.

The synergy between the two firms would deliver enhanced value and adaptability to clients, navigating the complex landscape of business transformation together.

Adamantia co-founder Jean-Baptiste Coiffet said: “In Protiviti, we have discovered not only complementary offerings but also an entrepreneurial culture and a focus on human capital that aligns perfectly with our core values.

“The team’s robust business expertise, particularly in financial services, coupled with its extensive international client base, provides a solid foundation for our future growth.”

Adamantia is a consulting boutique that provides high-value-added advisory services to financial institutions and corporations.

The company combines deep industry expertise with innovative methodologies to deliver tailored solutions that promote sustainable growth and long-term success.

With a network of over 90 offices in more than 25 countries, Protiviti offers deep expertise, objective insights, and a customised approach to help business leaders.

Protiviti and its independent member firms offer consulting and managed solutions across finance, technology, operations, data, digital, legal, HR, risk, and internal audit.

Protiviti international operations executive vice president Andrew Clinton said: “We have been impressed by the people we have met at Adamantia and are confident that they will help us deliver even greater value to our clients in France.

“In addition to extending our capabilities in France, a significant market for us, this acquisition will also enable Adamantia’s clients to benefit from our services in their operations around the world.”
