Generally speaking, grants (money that does not have to be repaid) do not exist in support of for-profit entities. There are a few exceptions.
One exception is a few U.S. Dept. of Agriculture (USDA) grants for producers. Find information about these grants on the USDA website, or visit the local Farm Service Agency (FSA) office, using the Farm Service Center locator.
Another opportunity is the City of La Grande’s grant programs for businesses located within the Urban Renewal District.
Business Oregon provides some federal grant funding for technological start-ups at their Small Business Innovative Reseach support program.
