A-Street, the education‑focused multistage investor founded by former Walmart family foundation staffer Marc Sternberg and Tom Kuo, has closed its second fund at $675 million. Backers include Walmart heirs and the Lego Foundation, the charitable arm that holds a stake in the Danish toy maker. The capital will target early‑stage education ventures in schools across the United States and abroad and worldwide expansion.

Marc Sternberg, who previously led the New York City Department of Education, said the fund remains open to additional investors. The lineup signals a growing appetite among high‑net‑worth families to channel capital into educational technology and workforce programs. A-Street plans to deploy funds through co‑investment structures that align with its founders’ experience in private equity and venture capital strategies for future growth.

With the Lego Foundation’s involvement, the fund brings a unique blend of philanthropic and commercial expertise. Investors anticipate that the capital will accelerate product development for learning tools and digital platforms. A-Street’s second fund illustrates how family‑wealth vehicles are redefining impact investing within the education sector, potentially reshaping funding flows for the next decade and innovation ecosystems globally for youth.
