Tetra Tech

Lauren Springer has moved up to president of the government services group at the global technical and engineering services provider, which she first joined in 2000.

With this promotion announced Tuesday, Springer now leads a business that has integrated federal technology work into its portfolio over the past several years. In January, Tetra Tech purchased Halvik Corp. to add agile delivery and digital solutions content.

Springer also currently works as president of Tetra Tech’s U.S infrastructure division.

Tetra Tech posted $5.4 billion in revenue for its 2025 recent fiscal year ended Sept. 28 and U.S. federal work represents 31% of that, according to the company’s annual report. The government services group contributed 49% of overall fiscal 2025 sales for Tetra Tech, which ranked at Position No. 64 on the 2026 Washington Technology Top 100.

Agile Six

Dan Levenson has moved up to chief executive at the digital services provider, which he first joined in 2018 as a strategy lead.

Levenson became president of Agile Six in 2020 and now oversees all aspects of the company’s strategy centered around product and delivery management, the DevSecOps software practice, data and applied artificial intelligence, and user-centered design and research.

Agile Six has recorded $25.1 million in unclassified prime contract revenue over the trailing 12 months with the Veterans Affairs Department representing 97% of the spend, according to USASpending.gov data. The Health and Human Services Department makes up the remaining 3%.

Levenson succeeds Robert Rasmussen, who co-founded Agile Six in 2014 and led it ever since as CEO. Rasmussen is staying involved as chairman of the board of directors, Agile Six said in a LinkedIn post.

Defcon AI

Margo de Naray has joined the integrator of artificial intelligence-centric technology systems as chief executive following a one-year stint as CEO of Solestial, a space solar tech outfit.

Defcon AI opened for business in 2022 and closed a $44 million seed capital raise two years later from a network of backers including Fifth Growth Fund and Red Cell Partners, the tech incubation firm.

De Naray now leads a company touting a $150 million contracted revenue backlog across four large customers, Defcon AI said Tuesday. She succeeds Yisroel Brumer, who co-founded the company alongside Red Cell Partners CEO Grant Verstandig.

Solestial was acquired by York Space Systems in May. De Naray’s two-decade career in industry also includes senior roles at Astra and Cargill.

Emagine IT

Aamir Saleem, who co-founded the technology services contractor in 2002 alongside company President Song Pak, is returning to the CEO post after a one-year stint as its chief technology officer.

During that period, EIT was led by CEO Cedric Sims as Saleem worked to refine the company’s technical vision and strategic direction. EIT’s LinkedIn announcement of Saleem’s return to the CEO role noted Sims’ leadership of the company during that transition.

EIT has recorded $23.9 million in unclassified prime contract revenue over the trailing 12 months with HHS representing 49% of the spend, according to USASpending.gov data.

Other significant prime customers include the U.S. International Development Finance Corp., plus the Interior and Defense departments.
