Learn from Jörn Weber — OSINT Practitioner for Over 35 Years
Former police detective, online investigator, and founder of corma GmbH. Jörn Weber teaches you OSINT methods that work daily in real investigations — from fundamentals to advanced techniques.
From Police Detective to OSINT Trainer
From the Streets to the Net — An Investigator's Career Through Changing Times
Jörn Weber's career began long before the internet as we know it today. He spent nearly 20 years as a police detective — a time when investigations were conducted with phone books, filing cabinets, and personal contacts.
The Digital Pioneer
In 1995, when the internet was still in its infancy, Jörn Weber recognized the potential of digital research. He created the first German police website — a revolutionary step at a time when “online investigations” were still science fiction for most people.
The Step into Independence
In 1999, Jörn Weber founded corma GmbH. His goal: Professional online investigations for companies and organizations. What started as a small investigation office developed into one of the leading providers of OSINT services in the German-speaking world.
From Investigator to Trainer
Over the years, more and more requests came in: “Can you show us how to do this?” Agencies wanted to train their investigators. Companies sought internal OSINT capabilities. What began as occasional in-house training became Jörn Weber's second calling: Passing on his knowledge.
Today: Practitioner and Trainer
Jörn Weber is both: He conducts daily online investigations at corma AND teaches his knowledge in trainings. That makes the difference: You learn from someone who doesn't just know the methods, but applies them daily.

Jörn Weber's Training Philosophy
1. Practice Over Theory
“I don't show you 100 tools. I show you the 10 tools you really need — and how to use them professionally.”
2. Structured Methodology Instead of Trial and Error
“OSINT isn't an art, it's a craft. You don't need magical abilities, just a clear process.”
3. Reproducible Results
“A good investigation must be reproducible. Not only should you understand the result, but also your colleagues or a court.”
4. Lifelong Learning
“OSINT constantly evolves. That's why all online course participants receive lifetime access and all updates free.”
5. From First Research to Finished Report
“I don't just teach you research techniques, but the complete workflow — from briefing to documentation.”
“Many think OSINT means knowing secret tools. That's wrong. OSINT means working systematically. The best investigators aren't those with the most tools, but those with the clearest methodology.”
