## Tips for applicants

- The Lead Agency mechanism requires tight coordination: nominate a Swiss or lead-funder partner early and align all proposal documents before the SNSF deadline.
- Check eligibility rules at each co-applicant's national funder; misaligned career stages or institution types across countries can block funding.
- SNSF targets the top 20%, projects must demonstrate clear added value from cross-border collaboration, not simply add parallel work streams.
