About Us

Ceniarth, LLC

Ceniarth is a single-family office focused on funding market-based solutions that benefit underserved communities. Through our investing activity, we provide capital to accelerate the deployment of products and services that directly impact underserved communities. We aim to support enterprises in ways that lead to long term commercial sustainability.

We organize our work around program areas that aim to think systematically about sector development and the obstacles to growth. We endeavor to support market ecosystems in ways that attract ongoing private investment or public sector support.

Ceniarth began operations in 2013 and works in conjunction with the Isenberg Family Charitable Foundation. Our ability to leverage grants and program-related investments, in addition to return-seeking capital, allows us to think flexibly and creatively to address funding gaps. Our goal is to apply the right, most efficient form of capital for a given need in order to produce meaningful impacts for communities.

Our program work is global and will aim to address both underserved communities in developing markets, as well as low-income communities in more developed economies. Our professional team is a small, but global organization with professionals currently based in London, Boston, New York, and San Francisco.

We deploy appropriate investment capital to support entrepreneurs and organizations tackling problems that impact the lives of people in underserved communities.


The Isenberg Family Charitable Foundation

The Isenberg Family Charitable Foundation is a private, family foundation founded through the generosity of the late Eugene (“Gene”) M. Isenberg and his wife Ronnie Isenberg. A serial entrepreneur, Gene successfully built a string of industrial enterprises, most notably serving as CEO and Chairman of Nabors Industries. Under Gene’s leadership, Nabors grew from a small, drilling company employing 300 people in 1987 into the world’s largest land and offshore platform driller, currently employing over 29,000.

From humble beginnings in Chelsea, Massachusetts, Gene often remarked that “his success far surpassed any expectations he had when he was younger”. He, therefore, offered philanthropic support to causes he believed in, particularly education, medicine and the performing arts. Gene was a particularly strong advocate of education, often making resources available to those who were unable to afford or access quality education.

Gene was a dedicated supporter of his alma mater, the University of Massachusetts Amherst (UMass Amherst). He had served as both President and Board Member of the UMASS Amherst Foundation, as well as co-chair of the university’s ongoing, $300M UMass Rising campaign. In recognition of his contributions and leadership, the UMass business school was named The Isenberg School of Management.  Gene greatly valued interdisciplinary learning and established three endowed chairs-in the School of Management, the College of Natural Sciences and Mathematics, and the College of Engineering. In addition, the Isenberg Awards, individual scholarships to graduate students who combine management with science and engineering, continue to be granted annually.

As current Isenberg School of Management dean Mark Fuller remarked, “during our very first meeting after I became dean, Gene made the point that ‘education is at least part of the solution to any problem.‘  To that end, Gene and Ronnie were also instrumental in the founding and support of the Parkside School in New York, which provides special education to elementary school children.

The Isenberg Family Foundation will continue to work in the spirit of Gene’s legacy supporting entrepreneurs, empowering underserved communities, and trying to provide equal access to opportunity to all people regardless of income level.
