ImmixGroup

ImmixGroup serves as the connective tissue between technology manufacturers and government agencies. First, the firm resells technology to the government through its contract vehicles on behalf of many manufacturers and channel partners. Additionally, it offers contract compliance and consultation services to firms looking to expand their public sector business. But like many companies whose revenue is closely tied to government spending, looming budget cuts could have an impact on its bottom line.
