A bespoke art advisory firm, renowned for tailor-made stewardship and high-end services.
Leveraging over 20 years of unparalleled expertise and a meticulously cultivated global network of elite partners, we deliver services of unmatched calibre—setting the definitive standard for excellence on a truly global scale.
NTRETA CAPITAL MANAGEMENT (NCM) is a discreet advisory firm specialising in fine art collection management at the highest international level. We are not engaged in art sales. Our role is to provide strategic, long-term oversight across the entire spectrum of collection care including curatorial planning, conservation, logistics, installation, framing, fabrication, and estate-related matters. We operate through enduring collaborations with world-class partners and institutions, ensuring services of unparalleled calibre. Trusted by a highly select international clientele, we offer access, structure, and quiet continuity — honoring the trust and legacy entrusted to our care.
Our sphere of engagement is unequivocally global — extending with measured discretion to where the finest art and its custodians reside.
At NCM, our relationships rest upon an implicit covenant of precision, discretion, and unwavering reliability. While we eschew conventional service level agreements, we uphold rigorous standards meticulously tailored to the unique demands of each engagement. These bespoke commitments ensure that every facet of our stewardship is conducted with the utmost attention and accountability — a standard befitting the distinguished collections we are privileged to oversee.
We provide art collection management services of the highest calibre, working exclusively with longstanding clients and a select circle of new collectors personally introduced to us.
Should a prospective collector approach us without a prior introduction from an existing client, a preliminary 45-minute consultation may be arranged upon advance payment of a $1,000 retainer. This meeting serves to determine whether our involvement would be appropriate — or whether a discreet referral might better serve all parties.
Please be advised that, prior to the commencement of any engagement, our legal partners undertake rigorous compliance reviews fully aligned with all applicable United States laws and regulations. This includes mandatory and enhanced screening protocols, alongside comprehensive due diligence processes, thereby ensuring the integrity of our operations and maintaining the fiduciary standards inherent to the advisory relationship.

We offer discreet, long-term advisory for families, institutions, and private collectors seeking to define or refine the structure of their collection. This includes succession planning, curatorial direction, tax-sensitive estate strategy, and legacy placement — all shaped with an eye to permanence, dignity, and discretion.
We believe that thorough documentation is the backbone of responsible collecting. We oversee the recording of provenance, condition, conservation history, and relevant transactional records, ensuring that every work is both historically grounded and institutionally legible.
We coordinate valuation services for insurance, estate purposes, donation, or acquisition planning. Working exclusively with vetted appraisers and subject-matter experts, we ensure that assessments are accurate, well-contextualised, and compliant with jurisdictional standards.
We supervise the care and conservation of works across media, engaging leading conservators where required. Our role is to ensure that treatments are appropriate, reversible, and aligned with the ethical standards of museum-grade restoration practice.
We oversee the secure movement, installation, and long-term storage of artworks — from climate-controlled crating and shipping to customs clearance and on-site handling. Our coordination ensures that every technical detail is handled with invisible precision.
We advise on insurance strategies tailored to the collection’s nature and structure, including review of policies, broker liaison, and risk assessment. We ensure that cover is proportionate, responsive, and embedded within a broader framework of protection and continuity.
We address what is seldom asked because true understanding precedes inquiry. Here, we provide the clarity and assurance expected by those who operate beyond question.
Discretion. Precision. Results. We deliver as promised, drawing on an unparalleled network of globally recognised professionals — each engaged with intent, never by chance. Our work is driven by insight, grounded in detail, and guided by a standard of business intelligence rarely spoken of and seldom encountered.
Our experience spans every corner of the globe, supported by an esteemed reputation and a network of distinguished contacts worldwide. We acknowledge that our fees reflect our exceptional calibre; yet, it is far wiser to invest once in unparalleled expertise than to risk multiple costly missteps or a single failure that could prove far more expensive.
Our extensive, trusted, and rigorously vetted network of professionals is the cornerstone of our excellence. With over two decades of experience in this field, we have cultivated partnerships with only the most distinguished and carefully selected experts — each one exemplary in their discipline, ensuring that our services remain unparalleled in quality and reliability.
Should prospective clients require any further clarifications or wish to address additional matters, we invite them to submit their inquiries to enquiries@ntretacapital.com.
