Investors conducting due diligence on Tempus AI must scrutinize its 510(k) clearances or De Novo classifications, as well as its strategy for generating Real-World Evidence (RWE) to supplement traditional clinical trials. The data moat that Tempus AI aims to build must be defensible not just technologically, but also legally and ethically, adhering to the highest standards of data governance and patient consent.

HIPAA Compliance as an Enterprise Procurement Filter

For A1 investors and A7 health IT professionals, HIPAA compliance is not merely a regulatory hurdle; it is an enterprise procurement filter that dictates market access and scalability. Any AI health app seeking large employer or health-plan contracts must demonstrate an impeccable compliance posture, moving beyond self-attestation to external validation. The HIPAA risk tracker for major AI health apps must consider several key dimensions:

• Data Security and Privacy: HITRUST certification or at least SOC 2 Type II attestation is rapidly becoming table stakes. Companies without these, regardless of their clinical promise, will be disqualified from significant contracts.
• Transparency and Auditability: The black box nature of some AI models is unacceptable in healthcare. Platforms must offer transparency into their algorithms, data sources, and decision-making processes, especially for applications that directly impact patient care.
