At INAA, we believe in the power of collaboration to amplify expertise, drive innovation, and deliver real results for businesses around the world. That belief has taken a decisive new step forward.

We are proud to announce a strategic global alliance between ALTAC International and INAA—two independent, highly respected professional groups with a shared ambition: to strengthen the reach and impact of professional services across borders.

A Milestone Partnership, Rooted in Shared Values

This alliance brings together more than 200 firms across 50+ countries, combining complementary strengths and a unified vision of excellence. By joining forces, ALTAC and INAA significantly enhance the ability of their member firms to serve clients in an increasingly interconnected and complex world.

What unites us is more than just a global footprint. It’s a shared approach—proximity to clients, deep industry knowledge, and the ability to provide strategic, legal, accounting, and financial advisory services with both local insight and international perspective.

A Global Footprint with Local Intelligence

From São Paulo to Singapore, from Paris to Johannesburg, the combined reach of our alliance connects clients to trusted professionals who understand the local business landscape—and who are equipped to act on global challenges with agility and precision.

This means that wherever your business operates—or aspires to operate—you’ll have access to a seamless ecosystem of advisors who are aligned in their approach, values, and commitment to quality.

Why This Alliance Matters

For the clients of our member firms, this alliance offers:

  • Unmatched access to cross-border expertise and specialized knowledge

  • Stronger international support for complex transactions, growth strategies, and compliance requirements

  • A future-ready approach to problem solving, rooted in collaboration and tailored solutions

This is not just about scale. It’s about strategic alignment—creating value by combining the entrepreneurial spirit of independent firms with the stability and experience of global reach.

Shaping the Future of Professional Services

We see this alliance as the beginning of a new chapter—one that will reshape how professional services are delivered, how cross-border business is supported, and how value is created in a global economy.

At INAA, our mission has always been to empower member firms to serve their clients better, wherever they are. This partnership with ALTAC reinforces that mission and opens the door to new possibilities—for collaboration, for innovation, and for impact.
