Custament Partners LLC
Founded by Christopher O.H. Williams, a global executive with over two decades of experience helping some of the world’s best-known consumer brands grow and transform, we are a boutique advisory firm that works closely with clients who seek to transform their organizations or sectors.
At Custament, we believe that every organization has the potential to transform into a bigger version of itself and that the secret to this success is challenging convention and innovating new standards of performance. We exist to enable this potential for our clients.
Our mission is to enable leaders and organizations to unlock their true potential and create consequential change with purpose and courage.

Our name is our promise.
Custament means relationship (we care), trust (we commit), reliability (we deliver), authenticity (we are open) and integrity (we do the right thing).
Our name “custament” hails from the crowded street markets of Sierra Leone, West Africa. It is the term that businesses and vendors - large and small, and their customers, use to refer to their most trusted and favored partner, with whom they prefer to work on a continuous, consistent, and sometimes exclusive, basis.
We offer world-class experience, hands-on engagement, pragmatism, and flexibility – all at a compelling investment. We are future-focused and bold. We collaborate and we teach. We cater to your enterprise. We are always people centered.
These are Custament values.
Our Clients
We specialize in working with innovators, challengers, and disruptors, with whom we collaborate to redefine their future. We are the trusted partner and the helping hands for the leader who is thinking “What if” and “Why not.”
Our clients are leaders and decision-makers – senior executives, corporate heads, boards, and principal investors - from a diverse range of industry sectors but who tend to have one or more of the following attributes in common.
