## Summary

The SNSF Weave Lead Agency funds bilateral research collaborations between Swiss and Czech research teams for up to 36 months. The call is open to researchers at institutions in both countries and requires co-submission to the Swiss National Science Foundation (SNSF) and the Czech Grantová Agentura České Republiky (GACR), with both teams working under a single project agreement. Weave runs annually with two submission windows per year.

## Who should apply

- Researchers based at Swiss and Czech research institutions
- Teams with established bilateral research partnership and joint project plan
- Applicants with capacity to manage simultaneous submissions to two national funders
- All research disciplines eligible under SNSF funding scope

## Key dates

- GACR deadline: 31 March 2026; SNSF deadline: 1 October 2026 (submit to either agency as Lead Agency, copy to the other within 7 days)
- Single-stage application process
- Project duration: up to 36 months, same start and end dates in both countries

## Tips for applicants

- Choose your Lead Agency (SNSF or GACR) carefully based on your home institution, the Lead Agency deadline differs (31 March vs 1 October), so plan submission timing accordingly.
- Both Swiss and Czech budgets must be internally aligned and justified on the same timeline; mismatch in team sizes or cost structures raises red flags in review.
- The 7-day cross-border filing window is tight: coordinate with your co-applicant and prepare the copy submission before the first deadline.
