What NeoSystems does
NeoSystems (operating as NeoSystems ESG LLC) was a Reston, Virginia-based managed services provider that delivered back-office operations support to U.S. government contractors, nonprofit associations, and select commercial clients. Its core offering spanned managed accounting services with DCAA compliance expertise, managed human capital (payroll, HR compliance, recruitment process outsourcing), financial planning and analysis, managed IT, and CMMC cybersecurity program services. The firm combined professional services delivery with a portfolio of proprietary software — NeoEnclave for CMMC-compliant secure computing, NeoFlow for workflow automation, and modules including Concur Connector, iRevu, Ethical Advocate, and a Policy & Procedure Manager — alongside resale and consulting around Deltek Costpoint, SAP Concur, UKG Pro, IBM Cognos Analytics, and Workday Adaptive Planning.
The business operated a direct enterprise sales motion targeting mid-market organizations with complex compliance needs, particularly defense contractors requiring DCAA-compliant accounting and CMMC certification. Pricing was quote-based and not publicly disclosed, consistent with bespoke managed-services engagements. Cumulative disclosed funding was approximately $20.1 million across 2009 and 2014 rounds led by OFS Capital, Clearsight Advisors, and Salem Capital Partners.
In May 2026, the original NeoSystems LLC entity entered dissolution after failing to secure capital, issuing termination notices to approximately 70 employees. Separately, the NeoSystems ESG managed accounting division was acquired by BlueStreet Solutions Inc., a Chantilly-based firm, with the company website indicating continuation of government-contractor back-office services under new ownership.
