## Eligibility & scope

Pilot Weave Lead Agency scheme between SNSF and AEI (Spain) enabling joint Swiss-Spanish research project proposals; part of SNSF's Project Funding scheme with standard national eligibility rules and each agency funding its own beneficiaries.

## Summary

Weave Lead Agency Spain is a pilot scheme between SNSF and Spain's AEI that funds joint Swiss-Spanish research projects over 36 months, under SNSF's Project Funding rules. Each national research group applies through its own agency, but only one lead agency reviews the joint proposal, cutting duplicate evaluation for bi-national teams. It suits Swiss and Spanish research groups with an established or planned collaboration who already meet their national agency's standard project-funding eligibility.

## Who should apply

- Research groups in Switzerland and Spain with an active or planned joint project
- Applicants who meet standard SNSF Project Funding eligibility (Swiss side) and AEI PID2026 eligibility (Spanish side)
- Teams able to coordinate a synchronized submission across two national agencies within a 7-day window
- Projects suited to a 36-month funding period

## Key dates

- AEI PID2026 deadline: 24 November 2026, with the Swiss mySNF copy due within 7 days after
- Further cut-off: 1 October 2027
- Project duration: 36 months

## Tips for applicants

- Coordinate submission timing tightly: the Spanish partner files with AEI first, and the Swiss partner has only 7 days after that deadline to submit the mirrored proposal via mySNF.
- Because only one lead agency reviews the science, align the two national applications closely in scope and budget before submission to avoid inconsistencies flagged in review.
- Confirm each partner meets their own agency's standard national eligibility rules, Weave changes the review process, not the underlying SNSF or AEI eligibility criteria.
