Goal: I need another 40.000 business adresses of Persons working in IT positions in Germany. All persons should have leading positions in companies in IT positions (IT Leader, IT Administrator, and IT Security Specialist) Contact Information needed: Company Name Comany Adress Person Name Website Phone email ATTENTION!!! Specialized IT Companies should not be in the result. This means Companies providing IT Services should no be in the contact options. (For example: Herold IT Service GmbH, …) Online Ressources I could imagine to find such contacts is for example [login to view URL] - it is a business platform. But also phone calling to companies and asking for contacts name could lead to result. Please offer with research planing and sample research of min 20 adresses.
