There are a lot of advertisements for free grant money for businesses and for 99.9% of businesses this is not true! Yes there are some grant funds, but they tend to be for science & technology companies (SBIR/STTR). Sometimes there will be agriculture, tourism, recycling or energy improvement grants that primarily come from states. Last there are occasionally a few non-for-profit groups that provide money to women, minorities and veterans. Those aren’t consistent enough to bank any business funding on.
You can see any federal grant opportunities at no cost by going to grants.gov, but we don’t recommend putting a lot of time into searching. Don’t pay for information about free grants, even those that make guarantees as you will likely be disappointed.
