About

Castelion is a defense startup developing the Blackbeard hypersonic missile system, one of the few startups with an active US Navy contract for hypersonic weapons full-scale prototyping and early operational fielding. The company raised $350 million in Series B financing in December 2025 and secured a $50 million US Navy contract for Blackbeard prototyping, directly addressing the DoD's urgency to field hypersonic strike capability as China and Russia have demonstrated operational hypersonic weapons.

About

NEOGOV is an El Segundo, California-based human resources software company founded in 1999 that focuses exclusively on the public sector. The company provides an integrated HR and talent management platform used by over 6,000 government agencies, including cities, counties, state governments, and school districts. NEOGOV's mission is to help government agencies modernize their HR processes to attract, hire, develop, and retain public sector employees more effectively.\n\nThe NEOGOV platform covers the full government employee lifecycle: Insight (applicant tracking and recruiting), Onboard (new employee onboarding), Learn (learning management system), Perform (performance reviews), and Comply (policy acknowledgment and compliance). The platform includes government-specific features such as civil service exam scoring, veterans preference processing, and classified position management that are required by government HR regulations but absent from commercial HR platforms.\n\nNEOGOV targets HR departments at local governments, state agencies, and public safety organizations. Its deep public sector specialization creates high switching costs and strong retention. The company competes with Workday Government, Oracle HCM, and general HR platforms adapted for government. NEOGOV differentiates through its purpose-built government compliance features, its massive reference base of 6,000+ agencies, and its integrations with government payroll and ERP systems.
