Clavis Orbis is a strategic consulting practice founded on a rare combination: intellectual rigor, operative ancient knowledge, and concrete understanding of contemporary systems (business, technology, institutions, geopolitics).
In the heart of historic Paris: the alliance of ancient metaphysical knowledge and cutting-edge technologies.
Clavis Orbis is founded and led by Julien Charles Lerat — jurist, philosopher, practitioner of the mantic arts of East and West, and designer of the house's proprietary analytical systems. His background combines the rigor of philosophy of science, metaphysics and law with mastery of the most ancient mantic traditions: horary astrology, geomancy, Yi Jing, Qi Men Dun Jia, Zi Wei Dou Shu, Xuan Kong Da Gua. He is also a practitioner of acupuncture point chromotherapy® and a hypnotherapist.
This interdisciplinarity is not decoration: it constitutes the very architecture of Clavis Orbis's analyses.
The Ambition
The ambition of Clavis Orbis is simple and demanding: to offer, within a framework of strict confidentiality, a reading and decision-making apparatus designed for high-intensity strategic situations — when stakes are asymmetric, information incomplete, timing decisive, and errors costly.
At the Interface of Two Worlds
The work sits at the interface of two worlds:
On one side, the standards of a high-end consulting firm (clarity, method, deliverables, accountability, governance);
On the other, proven symbolic systems (sometimes millennia-old) used not as beliefs, but as instruments of structuring: reading constraints, identifying levers, prioritizing scenarios, detecting blind spots, and above all — the art of timing.
Hermetic philosophy and celestial mathematics — the antechamber of decision
Our Clientele
Clavis Orbis serves extraordinary individuals, often in the public eye — executives, entrepreneurs, diplomats, senior officials, artists, free spirits driven by a sense of History, classical culture and a quest that transcends them. The house chooses its engagements. Each mission requires alignment with its standards of discretion, rigor and precision.
Access is deliberately selective: availability is limited, and every engagement requires alignment with our standards of discretion, seriousness, and precision.
Languages
French (primary); fluent English. We now work in most languages through oral and written translation systems managed internally for data security and confidentiality.
Format
Remote (video / audio / written) or in-person as feasible, and always in a confidential manner.
Paris
The firm is located in the heart of Paris, great heiress of Hermetic philosophy.
