Background

The Siegel Family Endowment was founded in 2007 as the Siegel Charitable Foundation and was renamed the Siegel Family Endowment in 2011 when it was granted charitable status. The foundation was founded by David M. Siegel, the founder of Two Sigma, a financial services company that is also paid to operate the finances for the Siegel Family Endowment. Siegel provided initial funding for the organization and continues to fund the organization with his personal wealth. As of 2021 the foundation managed over $415 million in assets. ⁷

The foundation describes 2012 to 2014 as its inaugural grantmaking years, listing its early grant recipients as the Massachusetts Institute of Technology (MIT), New York City FIRST, and the Scratch Foundation (then called Code-to-Learn). In 2015, the foundation hired its first executive director, developed its first mission statement, and developed its funding interest areas of “computational thinking, EdTech, and career readiness.” In 2016 the foundation added “Open Learning” as a funding interest area and from 2017 to 2018 the foundation “doubled down on our commitment to the computer science movement by incubating CSforALL in-house.” From 2021 to 2022 the foundation stood up its internal research team and hired its first cohort of research fellows, publishing several whitepapers including one titled “Schools as Community Infrastructure, which offers a vision for schools and learning as vital public goods.” ⁸

According to left-leaning philanthropic consulting company Arabella Advisors, the Siegel Family Endowment is focused on understanding and shaping the impact of technology on society. ⁹ The far-left concept of equity is at the heart of the Siegel Family Endowment’s work and is integrated into every step of the grantmaking process. ¹⁰ Siegel Family Endowment supports a the far-left concept of a more equitable society, ¹¹ has published reports on economic issues it believes are race-based, ¹² supports research regarding the undefined concept of misinformation on social media platforms, ¹³ and supports investments regarding the far-left concept of economic inequity. ¹⁴ The endowment believes the Juneteenth holiday should be used to narrow what it identifies as racial housing gaps. ¹⁵

The Siegel Family Endowment is funded by the personal fortune of David Siegel, a computer scientist and businessman who co-founded Two Sigma, a technology and financial services company.

Previously, she worked at Two Sigma, Google, Big Brothers Big Sisters, and as an intern at the American Civil Liberties Union (ACLU). ¹⁸

Knight has claimed that the far-left concept of equity needs to be infused throughout the building process of artificial intelligence (AI) for the public interest ¹⁹ and participated in an online event hosted by left-leaning philanthropic consulting company Arabella Advisors about the development of artificial intelligence systems and language models for philanthropic organizations. ²⁰
