Subject, an AI-powered education platform serving grades 6–12, announced it has secured a $28 million investment led by Vistara Growth, with participation from NextEquity Partners, Green Street Impact Partners, and Outcomes Collective, alongside existing investors Kleiner Perkins, True Equity, L’Attitude Ventures, and Hannah Grey.
The growth investment follows nationwide momentum for Subject’s AI-powered curriculum platform and is designed to accelerate innovation while expanding access to accredited, personalized K–12 learning solutions for school districts and education organizations worldwide.
As schools and districts navigate evolving instructional requirements and increased accountability for student outcomes, many are moving away from legacy digital curriculum systems that have proven difficult to scale and measure. Subject is increasingly being adopted as a core instructional platform, enabling districts to broaden accredited course offerings, support multilingual and diverse learners, and deliver instruction more efficiently. The shift reflects a broader transition toward AI-enabled infrastructure that helps districts maintain academic rigor while doing more with limited instructional resources.
Subject plans to accelerate development of its AI-powered platform, expand its catalog of accredited courses, and deepen automation tools that support educators and administrators. The company also intends to scale go-to-market efforts across priority U.S. regions and strengthen partnerships with existing district customers.
Currently, Subject partners with nearly 1,000 schools nationwide across approximately 360 districts and organizations. The company delivers accredited middle and high school original credit and credit recovery courses, along with Teacher of Record AI and Multilingual AI solutions. Subject holds top accreditations and approvals, including from Cognia, WASC, UC-AG, NCAA, and the College Board.
