Strategic allies
Partnerships accelerate distribution, not editorial control.
IHPI is developing partnerships with recognized bodies including the United Nations Global Mental Health Task Force and similar organizations that can help convene serious decision-makers.
Partnerships are treated as accelerators for distribution and legitimacy. IHPI retains publication control, role clarity, and neutral technical framing.
