Apart Research — Legal Structure: Nonprofit (501(c)(3) via fiscal sponsor Ashgro Inc)

Note: The source text directly confirms that Apart Research uses Ashgro Inc as a fiscal sponsor and that Ashgro Inc is a 501(c)(3) organization. The source explicitly states donations are 'Tax-deductible through our fiscal sponsor Ashgro Inc, a 501(c)(3) organization.' This matches the claim that Apart Research's legal structure involves a nonprofit (501(c)(3)) via fiscal sponsor Ashgro Inc. The source does not explicitly state Apart Research's own legal status, but the fiscal sponsorship arrangement described is consistent with the claim.

Note: The source confirms Apart Research operates as an organization focused on research and field-building, but does not explicitly state its legal structure as a 'nonprofit research institute.' The claim's additional context about 'exploring for-profit AI safety models as of 2025' is not addressed in the source text at all. The source is from November 2025 but contains no mention of exploring for-profit models. The organization's nonprofit status is implied by its structure and funding appeals, but not explicitly confirmed in the excerpt provided.

Note: The source text describes Apart Research's mission, programs, and impact but does not explicitly state its legal structure as a nonprofit organization. While the context mentions 'operates as nonprofit; exploring for-profit AI safety models as of 2025,' this additional context is not found in the provided source excerpt. The source alone does not confirm or contradict the nonprofit legal structure claim.
