To apply to a fund, simply create a project. If your project matches the fund’s criteria (Correct: location, focus area and the funding required is within the maximum grant amount) it will automatically be submitted to the fund and be considered for funding.
Note that if your project is relevant to other funds, it will automatically submit to all of them, increasing your chances of getting funded.
You can submit as many projects as you’d like. You can break larger objectives or needs down into smaller projects. But each project needs to be distinct, with defined timelines and costs, to avoid duplicate projects receiving funding for work that’s already been funded.
