About
Arkenstone Defense is a Menlo Park–based operations and compliance platform that helps commercial technology companies sell to the U.S. Department of Defense and other federal agencies 123. The company emerged from stealth on 2026-07-07 with a $35M seed round and offers two products — Foundation, which handles FedRAMP, ATO and CMMC compliance and contract management, and Cohort, which provides payroll, benefits, HR and workforce operations tailored to cleared personnel 23. Arkenstone was co-founded by Peter Dixon (previously founder of defense software company Second Front Systems), William Treseder and Stanford PhD Rachel Olney, and operates with roughly 60 employees and three dozen initial customers 23.

“Building a great product that serves the warfighter is not the same thing as gaining access to the defense market.” — William Treseder, Co-Founder & COO, Arkenstone Defense, quoted in launch coverage, 2026-07-07 3
