To my person

Eric Steiner-Mantei, MBA

Digital Media Expert

My name is Eric Steiner-Mantei. I have been working as a media professional since 2005. I founded NEUESDIGITAL in 2014 to become a full-time entrepreneur for digital media solutions. In the meantime, I have gained valuable professional experience in well-known companies. In recent years, I have spent most of my working time designing, programming and operating websites and advising clients in this area, especially in the field of information security. My clients are located in Germany, Austria and Switzerland.

I founded SEEWARA® in 2021. With SEEWARA® we are developing the new accounting software for self-employed people and companies, which, as a cloud platform, connects accountants with accountants and covers the core services of modern, legally compliant accounting. In short: cloud collaboration software
