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
Community Brands is a private equity-backed software company headquartered in Duluth, Georgia, that operates a portfolio of over 13 software products serving associations, nonprofits, and government agencies. The company was formed through a series of acquisitions and mergers, bringing together brands including YourMembership, Abila (nonprofit accounting), Protech (Microsoft Dynamics AMS), Freestone (learning management), Crowd Wisdom (association LMS), and several others. Community Brands collectively serves more than 30,000 organizations across the association, nonprofit, and government sectors.\n\nThe Community Brands strategy is to create a comprehensive ecosystem of specialized software products rather than a single monolithic platform, allowing customers to choose purpose-built tools while benefiting from shared data standards, integrations, and marketplace connections between products. Its Community Brands Marketplace connects association software users with apps, integrations, and service providers — creating a platform-style network effect within the association software ecosystem.\n\nAs associations face pressure to demonstrate ROI to members and compete for engagement against LinkedIn and other professional networks, Community Brands' portfolio of engagement, learning, and career tools becomes increasingly strategic. The company's scale gives it R&D and integration resources that standalone AMS vendors cannot match, positioning it as a consolidator in the still-fragmented association and nonprofit technology market.
