Alexei Lazarov

Alexei Lazarov (also spelled Alexei Laxarov; Bulgarian: Алексей Лазаров) is the founder and CEO of Visibilio AI, a Sofia-based AI visibility platform, and a co-host of the Human × AI Conference 2026 in Vienna. Before founding Visibilio, he spent 27 years at Capital — Bulgaria's leading business weekly, founded in 1993 by Ivo Prokopiev and published by Economedia — where he held every seat in the newsroom, from reporter to editor, and ultimately editor-in-chief.

Visibilio AI is built around a single thesis: the first answer people receive no longer comes from a search result page but from a generative AI. Citations and mentions inside large language models are becoming the new domain authority — and most brands have no way to measure, let alone influence, how they are represented there. Visibilio addresses this with a system of 23 AI agents that scan, write, and publish expert content across a brand's channels on a continuous schedule, tuned for how LLMs decide whom to cite.

Lazarov's path from newsroom to AI company is a continuation, not a pivot. Twenty-seven years of editing a business publication meant twenty-seven years of answering one question every week: what do decision-makers actually need to read, and how do you make them read it? That editorial muscle, applied to the new grammar of AI search, is what Visibilio is built on.

The Human × AI Conference grew out of the same instinct. Lazarov co-created it as a yearly room where European founders, investors, policymakers, and researchers can talk to each other honestly about what AI actually means for the continent — without the marketing layer that dominates most industry events. The first edition takes place on May 19, 2026, at Hofstallungen MUMOK in Vienna, as part of ViennaUP 2026.

He then moves into a second interview with Helfried Carl, founder of the European Capital of Democracy, on the democratic case for European competitiveness.
