- Arkenstone Defense
Participated · Seed · Jul 2026
Arkenstone Defense provides a managed operating system that packages government contracting requirements—cleared workforce, payroll and benefits, personnel and facility security, compliance, and accreditation—into a single service for commercial technology companies. The platform is anchored by a Professional Employer Organization (PEO) that legally employs cleared workers and carries the layered functions companies need to win and deliver federal contracts. Arkenstone launched from stealth and is led by co-founder and CEO Peter Dixon and co-founder and COO William Treseder. The company reported that more than two dozen defense technology firms already use its platform. Arkenstone positions itself to reduce the operational lead time and cost of certifications like CMMC Level 2 and other accreditation lifecycles that previously forced startups to build separate government back offices. It is headquartered in Menlo Park, California, with additional offices in Albuquerque, New Mexico and Burr Ridge, Illinois.
- Critical Energy
Led · Seed · Jun 2026
Critical Energy designs and manufactures modular turbines and turbomachinery aimed at speeding deployment of geothermal power plants. The company leverages founder Spencer Jackson's SpaceX turbomachinery experience to produce factory-built modules that can be assembled faster than large, site-assembled turbines. Its immediate plan is to build a 2.5 megawatt turbine module as its first project, with a 5 megawatt module in development for enhanced geothermal operators. The first plant using its turbines is slated for completion by 2027. Financially, Critical Energy has raised $19 million in seed equity and $3 million in venture debt, totaling $22 million in early capital. The company projects rapid scaling, targeting gigawatt-scale output by the early 2030s and a long-term goal of producing 300 gigawatts of capacity per year by 2045.
