About Us

Ceniarth is the single family office of Diane Isenberg. We manage Diane’s personal assets, as well as the endowment and philanthropic activity of the Isenberg Family Charitable Foundation. Our goal is to invest the entirety of our capital base in impact-first investments benefitting marginalized and vulnerable communities globally. This includes personal assets, investments made from our Foundation’s endowment, and philanthropic disbursements in the form of program-related investments (PRI). When we say 100% impact-first, we genuinely mean directing all of our assets in ways that are credibly generating benefits for communities in need.

We use the term impact-first to differentiate from more conventional, finance-first impact investing strategies that target commercial returns and, consequently, are not always able to serve the most vulnerable. By contrast, impact-first investments are concerned first and foremost with directing capital into low-income communities, are often catalytic in nature, and may be flexible on risk and return parameters.

We invest in both funds & intermediaries with an emphasis on private credit, real estate, and real assets with a much more limited allocation to private equity and venture capital. We have a meaningful direct lending portfolio to a wide variety of social enterprises, microfinance institutions, and community development organizations. We perform all of our investment sourcing, diligence, and monitoring activities in-house with our team primarily based in London, but with a number of remote employees in the United States.
