Millions of people disappear each year worldwide. For their families and loved ones, a heartbreaking void is left behind. It is a painful and complex issue. We feel the urgent need to help. Especially in unsolved cases, so-called "cold cases".

Our expertise not only offers clarity, but also empathy. Every face we reconstruct, every route we visualize, tells a story. It is our mission to bring those stories to life with precision and respect, which sets us apart as pioneers in our field.

Our formula for success lies in the combination of forensic insight and deep human understanding. Thorough research, information gathering and exceptional insight enable us to create accurate reconstructions.
