With over three decades of experience in Enterprise Architecture (EA), systems engineering, and model-driven methodologies, Antoine Lonjon is recognized internationally as a thought leader in shaping the future of enterprise transformation frameworks. His unique perspective is rooted in a foundational insight: system architecture and economics share the same ontological foundations.
This conviction was sparked during his studies in micro- and macroeconomics at the University Paris-Dauphine in the 1980s. While intrigued by concepts like indifference curves, he felt a sense of intellectual incompleteness with neoclassical models. This feeling was validated by a wise teaching assistant who introduced him to the work of Paul Fabra, revealing a powerful alternative centered on the core concept of economic exchange.
In parallel, throughout his career, Antoine's work on the foundational models of system and enterprise architecture was converging on a similar principle. While contributing to key international standards like UML, BPMN, UAF, he identified economic exchange as a critical form of interaction for any enterprise. Before founding SysFEAT, he served as Chief Innovation Officer at MEGA International, where he led advanced research in ontology-driven modeling and AI-assisted design, solidifying his crucial realization that these two disciplines must inform one another.
SysFEAT is the embodiment of this insight. Its mission is to provide a unified yet modular framework where systems thinking and economic principles systematically enrich each other.
At SysFEAT, Antoine brings his strategic vision and technical depth to help organizations design, govern, and transform with confidence. A passionate advocate of systemic thinking, he combines academic rigor with hands-on experience to bridge systems thinking, economic insight, and engineering rigor. His ultimate goal is to empower organizations worldwide to navigate complexity and build purposeful, agile, and sustainable enterprises.
