Stefan Chiriacescu is a serial entrepreneur, AI architect, and the founder and CEO of eCommerce Today – a global fractional eCommerce department serving more than 300 Shopify and Shopify Plus brands across North America, Europe, and the Middle East.

He has owned and exited businesses on both sides of the Atlantic and has spent the last three years leading one of the more well-documented AI transformations in the agency space – growing revenue 11×, expanding from two services to seven, and building ETAOS, a proprietary AI-augmented operating system now running live across his organization.

Stefan advises companies on AI adoption and organizational design, and speaks internationally on what it actually takes to move from experimentation to structural transformation. He is scheduled to present at AI Summit Europe 2026 in Vilnius and has presented at Digital Marketing Europe in Lisbon.

His position has remained consistent: the goal is not to replace people. The goal is to make every person in an organization unreasonably capable.
