Our history

A story of continuous growth

International Advisers was founded in 1978. Our founder, the late Bram Hertzberger, started a small office in Amsterdam for debt collection management in Italy for a large Dutch credit insurance company. His son Chanan and later his daughter Naomi joined him and further assisted in the growth of the business.

During the 1980s and '90s, the company expanded considerably with collections throughout Western Europe.

After the founder's passing, Chanan Hertzberger (CEO) and Naomi Hertzberger (CFO) took over the leadership of the company. Together they form the company's Managing Board.

In the past 30 years, IA's list of clients has increased, with an emphasis on large, international export-credit insurers with worldwide interests.

We are proud to serve companies such as Sinosure, AIG, EDC, Credendo, K-Sure, Euler Hermes and several other valued clients.

Our staff of 58 lawyers, investigators, negotiators and other debt recovery and collection management experts work from our Amsterdam headquarters, while another 55 colleagues work at our local offices around the world.

We continue to grow as the leader in worldwide investigations and collection management, while assuring that our clients continue to receive the same personal and detailed attention they have been used to since 1978.

Because what we do, we do for 100%.
