Independent platform. Not affiliated with or endorsed by any government agency. Data from public federal sources.
Federal agencies list "small businesses" as eligible on many research, technology and economic development notices. The Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs are the best known, but they are not the only ones. Most notices use the size standards of the U.S. Small Business Administration to decide what counts as small.
The list below shows every open opportunity in our database whose official notice lists small businesses as an eligible applicant type. Each listing links to a summary page and to the official notice.
Being in an eligible group is only the first check. Read the eligibility section of each notice for location, program focus, cost sharing and other conditions before you start an application.

Frequently asked questions
Does being listed as eligible mean my organization qualifies?
No. The applicant type is only the first filter. Most notices add more conditions, such as location, program focus, matching funds or prior experience. Read the eligibility section of the official notice before you apply.
Is GovGrantsUSA a government website?
No. GovGrantsUSA is an independent platform operated by VRLY Ventures LLC. It is not affiliated with or endorsed by any government agency. Opportunity details are summarized from public federal sources such as Grants.gov.
Does it cost anything to apply for a federal grant?
Searching for and applying to federal grants on Grants.gov is free. Be wary of anyone who asks for a fee to "release" a grant or guarantees an award.
How current is this information?
Listings are refreshed from public federal data every day, and each page shows when it was last updated. Agencies can change or cancel a notice at any time, so always confirm details in the official notice.
What do I need before I can apply?
Most applicants through Grants.gov need an active SAM.gov registration with a Unique Entity ID (UEI), a Login.gov account and a Grants.gov account linked to their organization. Registration can take several weeks, so start early.
