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.
Lazarov takes the stage in three sessions during the day.
He opens the conference with an interview with political scientist Ivan Krastev — Chairman of the Centre for Liberal Strategies and Permanent Fellow at IWM Vienna — on what happens to liberal democracy when tech elites no longer need the public.
He then moves into a second interview with Helfried Carl, founder of the European Capital of Democracy, on the democratic case for European competitiveness.
Later in the afternoon, he joins Patrick Schmid of Rankscale AI for a practical use-case session titled "Your Brand in the Age of AI Search" — a working demonstration of how brand visibility is measured, diagnosed, and improved inside generative AI systems.

Visibilio AI is a visibility engine for B2B brands inside AI search. Its system of 23 AI agents scans, writes, and publishes expert content across a brand's channels on a continuous schedule, with the goal of making the brand more likely to be cited by large language models and AI search engines such as ChatGPT, Perplexity, Claude, and Gemini.
Sofia, Bulgaria. Visibilio AI is headquartered at 31 Alexander Malinov Blvd., 1729 Sofia.

Both refer to the same person. "Alexei Lazarov" is the canonical English spelling and matches the Bulgarian original Алексей Лазаров. "Alexei Laxarov" is an alternate Latinization that appears in some of his older public handles, including his LinkedIn username.
Three sessions on May 19, 2026 at Hofstallungen MUMOK in Vienna: an opening interview with Ivan Krastev on tech elites and democracy, an interview with Helfried Carl on the democratic case for European competitiveness, and a use-case session with Patrick Schmid of Rankscale AI on brand visibility in the age of AI search.
Join 200+ leaders in Vienna on May 19, 2026 for a day of insight, inspiration, and meaningful connections at the intersection of human potential and AI.
