# Antonios Kioksoglou

> Technical founder and software engineer in Gothenburg, Sweden, working where AI, e-commerce, marketing technology and product development overlap. CTO and co-founder of Zalster. This file is the short version of the site for AI agents and the people they work for.

Antonios combines engineering with commercial understanding: building software and automation while understanding how products are marketed, measured and turned into revenue. Everything below is documented on the pages linked from this file.

The terminal sessions on the Software page are scripted simulations, and the reporting workspace on the Marketing page uses made-up numbers. Both are labeled on those pages and neither is a client result. This site makes no claims about results for any client, and it does not state availability. Write with the brief, and the answer will say honestly whether it fits.
