How I think about me

Even though I am very creative and bring a little bit of crazy into my work, overall I work in a very structured and analytical manner. Thanks to my many years of experience, I can assess digital marketing very well and provide competent decision-making support.

This is what the publisher Springer Gabler writes about me

Thomas Klein is a certified social media manager and has been working in digital marketing since 2000. The almost lawyer in social security law founded his first internet startup in 2000. In the early years of commercial Internet use, he developed a WCMS and implemented over 300 commercial Internet sites.

In the first hour of social media in Germany (2009), he implemented the first social media strategy for a logistics company in 44 European countries.

In 2013, Klein published his first specialist book, “Social Media Methods”, published by Cornelsen Verlag. In 2015 he founded his social media agency sentimeo. This was followed by social media consulting mandates with the largest brands in Germany such as Deutsche Bahn, OTTO, Volkswagen and Zentis.

Today Klein is a lecturer and specialist in AI in social media marketing and is a speaker at conferences and events. His listeners appreciate him as a pragmatic expert who explains social media and influencer marketing in a nutshell.
