About us

Triangular Group (TG) has its origins in the intelligence domain. TG’s founders are former intelligence officers and TGA’s sister company, Triangular Group Intelligence (TGINT), has been active since 2014 in building up and improving intelligence positions in challenging countries in favor of its clients. It is therefore a logical consequence that Triangular Group Academy offers this specialist knowledge in the form of various courses.

Our instructors are internally supervised in terms of content and didactics. This gives them the knowledge and skills required for training at the highest level.

Operational manager

The goal of our courses is to truly prepare students for reality. That is why I strive to provide the highest possible quality education.
