GRAIN functions by collaborating with biomedical research structures, thereby presenting many benefits for PIs including, but not limited to the following:

1. Enables expansion of one's international network and connection with fellow EUHA members.
2. Presents opportunities to receive feedback from a panel of European clinical and translational experts including European Research Infrastructures.
3. Enhances a research idea's scalability and exploitation strategy.
4. Enables access to support from EUHA Member Grant Officers.

Since GRAIN's founding, more than 15 research proposals have been presented in GRAIN meetings, four joint proposals have been submitted, and several proposal collaboration requests have been shared by email. Furthermore, the initiative has successfully established a common space between EUHA, EATRIS, ECRIN, and BBMRI.
