Check or correct this record at the source: open its SAM.gov entry, or search UEI WDHYXM4WBZG8 () in SAM.gov's entity search (free sign-in) and in SBA's Small Business Search (formerly DSBS), which shows SBA certifications including VetCert.

Open contracts in The Critical Mass LLC's NAICS codes
320 open federal opportunities on SAM.gov use one of The Critical Mass LLC's NAICS codes and may be open to it: no set-aside, or, in the codes it is registered small under, a small business set-aside or one for a status it reports about itself on SAM.gov (service-disabled veteran-owned and women-owned (WOSB)). Here are a few, those in its primary code first (none of these are in Virginia right now), then the soonest due.
Confirm eligibility first. The Critical Mass LLC's service-disabled veteran-owned and women-owned (WOSB) status is self-reported on SAM.gov, and this page can't confirm an SBA certification for it, so set-asides for it may be relevant but may not be open to it: SDVOSB and VOSB set-asides need SBA VetCert certification and WOSB and EDWOSB set-asides need SBA WOSB program certification. SBA's Small Business Search shows a firm's current certifications.
