Imprint
This site is personal. It belongs to me, not to a company. If you are here about an AI project inside your organisation, that runs through Omniance and has an imprint of its own.
Provider
I live in Portugal. The details required by section 5 DDG and section 18 (2) MStV are given here in full anyway, because a large part of the readership is in Germany, Austria and Switzerland and rightly expects them.

Responsible for the content
Responsible for the editorial content under section 18 (2) MStV: Marcus Eichner, address as above.
VAT
There is no VAT identification number to list here. This site sells nothing and invoices nothing. Business runs through Omniance.
What is on this site
The posts are my own archive: texts I first published on LinkedIn. They reflect where I stood on their publication date, and that date is on every one of them. None of them is legal, tax or investment advice.
External links
I link to other people's sites, whose content I do not control and which can change after I have linked to it. If you find something there that is not right, write to me and the link comes out.
