## Summary

Weave Lead Agency funds bilateral Swiss, Czech collaborative research projects of up to 36 months, with simultaneous funding from SNSF (Switzerland) and GACR (Czech Republic). Swiss and Czech partners must be co-applicants hosted at institutions in their respective countries, with projects starting and ending on the same date. This call runs annually and is part of SNSF's bilateral Lead Agency scheme.

## Who should apply

- Swiss researchers hosted at Swiss institutions seeking Czech collaboration partners
- Czech researchers hosted at Czech institutions seeking Swiss collaboration partners
- Research teams prepared to coordinate simultaneous applications via SNSF and GACR
- Bilateral projects where both partners contribute substantively to research design and execution

## Key dates

- SNSF deadline 1 October 2026; GACR deadline 31 March 2026 (Czech applicants must submit to GACR first, copy to SNSF within 7 days)
- Single-stage simultaneous submission to both funders
- Up to 36 months project duration, with synchronised start and end dates in both countries

## Tips for applicants

- Coordinate your timeline carefully: Czech applicants must hit GACR's 31 March deadline to allow the SNSF copy to arrive by 7 April.
- Both partners must be named and active co-applicants in writing; lead, support relationships or token partnerships weaken your bilateral framing.
- Align your project scope, timeline, and budget distribution upfront with your partner to avoid conflicts during simultaneous review.
