Simplify's Take
What believers are saying
- ProSidian posted multiple NSF HR analytics roles in April 2026.
- June 2026 contract data shows $4.0M obligated across repeat federal buyers.
- GSA MAS validity through 2032 supports continued federal selling capacity.
What critics are saying
- PrimeRFP shows 41% of obligations came from NSF in June 2026.
- Eighty percent of obligations were not openly competed, risking renewal shocks.
- Without new federal recompetes, the firm risks collapse from contract loss.
What makes Prosidian Consulting unique
- ProSidian held a GSA MAS contract through May 17, 2032.
- ProSidian sells federal consulting across NSF, DoD, DOE, and Treasury.
- ProSidian positions itself in human capital, compliance, energy, and risk work.
