Episode notes
Predict Health Outcomes From Non-Health Data
- BranchLab trains neural nets on health data to predict health outcomes using only non-health inputs.
- This lets advertisers activate healthcare audiences without exposing sensitive health identifiers.
Adopt Privacy-First Modeling Now
- Use privacy-first models to avoid attaching health data to advertising IDs and meet evolving state rules.
- Lock sensitive data behind neural nets and deploy only lightweight probability outputs for activation.
State Laws Reshape Pharma Targeting
- State laws like Washington's My Health, My Data and New York's S929 are reshaping acceptable ad targeting.
- These laws make legacy pseudonymous targeting approaches legally risky for healthcare ads.
