## Eligibility & scope

Weave/Lead Agency scheme enabling joint Swiss-Croatian research projects; applicants submit either to HRZZ (Croatian Science Foundation) with a copy to SNSF via mySNF within seven days, or to SNSF as Lead Agency. Project duration and start date must match in both countries.

## Summary

Weave is a SNSF-led European collaborative funding scheme for researchers from 2-3 countries to submit joint bottom-up projects. The lead applicant submits through SNSF; co-applicants in other countries simultaneously submit to their national funders, with each funder covering the costs of its own team. The scheme targets the top 20% of proposals in each evaluation round.

## Who should apply

- Swiss researchers ready to lead a multi-country consortium
- Researchers from eligible European countries with strong national funder eligibility
- Teams with 2-3 partners from 2-3 different countries
- Bottom-up projects without predefined themes or targeted scientific areas

## Key dates

- Deadline: 1 October 2026 (annual calls also on 1 April)
- Single-stage joint submission via SNSF Lead Agency; co-applicants submit to national funders within 7 days
- Evaluation targets the top 20% of submissions

## Tips for applicants

- The co-applicant submissions to national funders must occur within 7 days of the lead submission; coordinate all co-authors on timing before you submit.
- Check eligibility at each co-applicant's national funder before drafting; ineligibility in one country can sink the entire consortium.
- Write a single joint proposal in English (unless based in Austria or Luxembourg); reviewers assess the whole team's fit, not separate national components.

## Frequently asked questions

### How does Weave funding work across countries?

The lead applicant submits a joint proposal to SNSF; co-applicants simultaneously submit to their own national funders. Each funder covers the costs of its researchers, so you receive Swiss funding for Swiss team members, and your co-applicants receive their respective national funding.

### How many countries and researchers must be in a Weave consortium?

You need 2-3 researchers from 2-3 different European countries. The lead applicant is typically based in Switzerland, and each co-applicant must be eligible at their national funder.

### What is the deadline for Weave?

The next deadline is 1 October 2026; calls occur annually on 1 October (and also 1 April).

### Can I submit a Weave proposal if I am not based in Switzerland?

Weave requires a lead applicant eligible at SNSF (typically Swiss-based); if you are abroad, you would be a co-applicant submitting to your national funder alongside the lead.

### What is the success rate for Weave proposals?

Weave aims to support the top 20% of submissions in each evaluation round, making it highly competitive.
