Ranked by federal prime contract dollars as a small business since FY2024 (USAspending.gov, as of Nov 5, 2026).

How these are ranked

Prime contract dollars since fiscal year 2024 on contracts where USAspending.gov counts the firm as a small business. “Small” is set per NAICS code: these firms are registered small under their primary code (or SBA-certified). Firms that hold small business subcontracting plans, which only businesses that aren't small file, or have $1 billion or more in these contracts are left out. A profile's yearly totals count all of its prime contracts, so they can be higher.

Hiring small subcontractors?

If you're a prime looking for small businesses to team with, use the filters above to list small firms by state, NAICS code and certification, then open a profile for its SAM.gov registration, the codes it is small under and its contract history. Check any firm by name, UEI or CAGE code with the CAGE code and UEI lookup.

About these profiles

Every business registered on SAM.gov as small under at least one NAICS code, and every SBA-certified firm, has a profile; each profile says which codes it is small under. Registration details come from SAM.gov's public entity extract and contract figures from USAspending.gov. Contact names and street addresses are left out. Looking for partners to team with?
