Grants.gov
Grants.gov is a one-stop shop for federal grant opportunities. To apply for a federal grant, you must obtain a unique nine-digit number for your business from Dun & Bradstreet. This DUNS number registers you as an entity that can conduct business with the US government through its System Award Management program. The grants provide billions of dollars that can make the application process worthwhile.
The grants.gov site offers guidance on 1,000 or more programs from 26 grant-making agencies in the federal government. While the paperwork may tax your patience, you might find an opportunity to fund your business plans through grants that welcome everyone to apply.
