In general, federal agencies tend to have more funds available to award across a wide range of research topics. The funds will typically cover all project costs. Application processes and deadlines are public information and very firm. They tend to know ahead of time about whether the funding will be renewed. Examples include:
Private funding tends to go toward addressing specific emerging issues or interests. These sources are more likely to collaborate with other sources, provide alternative forms of assistance, and consider experimental activities. Private sources may change their area of focus each grant cycle. They usually have fewer regulations and requirements than federal funders. Examples include:
Some universities provide options for pilot funding through the University and clinical and translational research center.
