In the US, many entrepreneurs see grants as “free money,” since they are not loans and don’t have to be repaid. A grant is not an equity investment, so the entrepreneur doesn’t have to give up a stake in the company either. Typically they can be used to fund product development and commercialization that would otherwise require outside investors.
A good place to start looking is the Small Business Innovation Research (SBIR) program, which is a lifeline for high-tech startups. A more general approach is to check out Grants.gov, which is a searchable directory of more than 1,000 federal grant programs. An advanced search tool is provided to search for a grant by eligibility, by issuing agency, or category.
