The Hy in HyBrayn: the people behind it.

HyBrayn is a European AI consultancy with its registered office and management in Varna, Bulgaria (EU). The company was founded in 2025 by two German entrepreneurs: Alexander Vallon and Jonas Lachowitzer. Today there are four of us — Moritz Paschold joined in engineering, Alessio Marini in marketing and sales. For web, iOS and Android development we work with a partner team in Indonesia: family, a team we have worked with for years, and with no access to client data or client systems. Advisory and support are delivered in German and English; cooperation is governed by EU law and the GDPR.

There is a simple reason the company sits in Varna: Alexander lives here. Legally, that changes nothing for you. Bulgaria is an EU member state and has been part of the euro area since 1 January 2026; the GDPR applies directly, exactly as it does in Germany. Our legal form, the OOD, is the Bulgarian counterpart to the German GmbH — a limited liability company in which shareholders are liable only up to their capital contribution. So you work with an EU company, in German, under European law, with direct access to the founders.
