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.
