A significant $35.0M seed round has just closed for Arkenstone Defense, a startup aiming to streamline how modern technology companies engage with the U.S. national security ecosystem. The capital infusion will bolster Arkenstone's unique offering: a dual-layered federal business back office infrastructure designed to remove execution friction.
This infrastructure helps companies with everything from compliance gaps and audit readiness (through its Foundation layer) to workforce, payroll, and labor compliance (via its Cohort layer). Investors participating in the round included J2 Ventures, Susa Ventures, Granite Hill Capital Partners, and ARTIS.
