# Federal Tech Firms Announce Leadership Changes

Tetra Tech, Agile Six, Defcon AI, and Emagine IT reported leadership changes, including new government-services leadership at Tetra Tech and CEO transitions at Agile Six, Defcon AI, and Emagine IT. The changes come amid varying federal customer exposure: Agile Six reported $25.1 million in unclassified prime contract revenue over the trailing 12 months, with 97% tied to VA; Emagine IT reported $23.9 million, with HHS representing 49%; and Defcon AI reported a $150 million contracted revenue backlog across four large customers. The article describes no new solicitation or contract award, but the leadership moves and customer concentration are relevant to contractor engagement, delivery continuity, and recompete positioning.

- Companies competing with or subcontracting to these firms should account for leadership changes in customer and incumbent engagement, particularly across VA and HHS work.
- Agile Six’s reported VA concentration and Emagine IT’s HHS exposure make those agency relationships material to assessing delivery continuity and potential recompete dynamics.
- Defcon AI’s reported backlog provides market context for its scale, but the signal does not identify specific contract opportunities or award actions.
