Andersen Iberia launches a consulting practice with Braintrust Consulting

Andersen Iberia has announced the launching of Andersen Consulting, in partnership with Braintrust Consulting, led by Juan Bosco de la Rocha, a data-driven strategic consulting firm, which will now operate under the Andersen Consulting brand.

Andersen Consulting will combine innovative business strategy, digital transformation, and AI-based technology solutions, alongside the firm’s expertise in tax, legal, economic valuations, and global mobility. With an independent business model, the new practice branch aims to offer an alternative to traditional consulting approaches, placing customer-centric commitment at the core of its success.

In Spain, Braintrust Consulting, a firm specializing in strategic business consulting driven by data and technology, becomes a member of the new practice area and will adopt the Andersen Consulting brand.

Led by its managing partner, Juan Bosco de la Rocha, Braintrust has over 20 years of experience with projects in more than 20 countries and focuses on highly competitive sectors such as telecommunications, banking, insurance, energy, tourism, hospitality, and retail, serving Ibex 35 companies. Braintrust also operates in South America, particularly in Chile. De La Rocha joins Andersen Consulting as partner and managing director in Spain.

Andersen Iberia, a Spanish member firm of Andersen Global, and Andersen Consulting will keep as independent firms both in terms of corporate structure and management. However, they will explore collaborations and business synergies.

This collaboration will allow Andersen Iberia to enhance and complement its legal and tax services with business and operational insights, leveraging data-driven technology. At the same time, Braintrust, as a member of Andersen Consulting, will provide its clients with access to the expertise of over 90 partners and 400 professionals from Andersen Iberia, covering all areas of business law and specializing in various industries and sectors.

According to Andersen, the launch of the consulting practice is a step forward in Andersen’s goal to expand and strengthen its services, with a firm decision not to establish an auditing division—now or in the future.

Juan Bosco de la Rocha, managing partner of Braintrust Consulting, stated that “At Braintrust, we have always thought big, with a clear global vision from the start. Now, as part of Andersen Consulting, this vision becomes a reality. Being a member of Andersen Consulting allows us to enrich and share our capabilities, culture, and values with all Andersen Consulting professionals, as well as with over 19,000 professionals in more than 500 locations worldwide, providing legal, tax, valuation, and global mobility services under Andersen Global.”

For his part, José Vicente Morote, managing partner of Andersen Iberia, highlighted: “As we have seen in our initial months of collaboration, the synergies between Andersen and Andersen Consulting allow us to offer clients a more sophisticated, comprehensive, and robust value proposition. The key to our early success is sharing with Juan Bosco and his team a culture based on excellence and a focus on high-value-added
