- • applied science with a concrete use case
- • teams working in health, resilience, or implementation settings
- • projects that need faster-moving challenge funding
What to watch before drafting

Why this page matters
Global Grand Challenges opportunities are strongest when the work sits between scientific rigor and a plausible path to adoption, delivery, or systems impact.
These calls are often the fastest way to see where philanthropic and challenge-led science funding is willing to move next.
