Simplify Jobs

Simplify's Take

What believers are saying

  • PrimerFP showed $4.0 million obligated firm-wide by June 2026, proving active execution.
  • Scoutify tracked 48 open roles on June 20, 2026, across Alexandria and Aiken.
  • The GSA schedule and 37 task orders support repeatable federal sales motion.

What critics are saying

  • Scoutify's June 2026 feed showed 73% fewer recent postings, signaling hiring deceleration.
  • FY2026 YTD obligations were only $119,744, exposing weak new-award momentum.
  • Without new federal recompetes, the 22-employee firm risks collapse from contract loss.

What makes Prosidian Consulting unique

  • ProSidian's CONUS/OCONUS reach spans six practice areas, from Energy to Human Capital.
  • Federal work is diversified across NSF, DoD, DOE, and Treasury contracts in 2026.
  • Its 2026 hiring spans engineering, data, and compliance roles, signaling multidisciplinary delivery.
