Oliver Peth

I am Oliver Peth, founder of Privat investigation Service DETEGERE and known as the German Sherlock® I specialize in corporate intelligence, fraud investigations, internal investigations, discreet observations, background checks, and sensitive international cases. I support companies, law firms, insurers, family offices, and private clients when reliable facts, discretion, and legally usable evidence are essential. My strength lies in combining expertise, business and operational thinking.

Professional and straightforward communication. Excellent accessibility and transparency. The final result was very good and met our complete satisfaction. Many thanks to Oliver Peth and his team for their great help. Highly recommended! We were very satisfied with the execution and all coordination. The investigations were conducted in a highly professional manner and yielded results suitable for use in court. Highly recommended. My matter was handled with the necessary care, and the result was excellent. Highly competent and friendly advice. Accessible at all times; questions were answered within minutes via WhatsApp. Top-notch! Very quick initial response. We can highly recommend you and would certainly turn to you again ourselves. Many thanks! Mr. Peth is a fantastic speaker who truly captivates the audience. The stories from his work as a profiler are gripping and highly educational. I would love to see him speak again! A big thank you to the team led by Oliver Peth for the outstanding planning and execution of my rather unusual assignment. 5 stars 😁 for German Sherlock! 💯
