What Castellan does

Castellan Inc. is a privately held, family-operated managed IT services provider (MSP) and IT consulting firm founded in 1999 and headquartered in Calabasas, California. The company delivers outsourced IT management, IT consulting, project management, helpdesk support, cybersecurity, cloud solutions, and network management primarily to small and mid-sized businesses across the Los Angeles metropolitan area, with named service-area coverage in Calabasas, Burbank, Santa Monica, Long Beach, Sherman Oaks, Glendale, Northridge, Woodland Hills, San Fernando, Orange County, and South Bay. Its technical capabilities are built on third-party platforms rather than proprietary software, including Microsoft Azure, Microsoft 365, Google Workspace, Azure Virtual Desktops, Barracuda, Veeam, Veritas, Backblaze, SentinelOne, Deep Instinct, Huntress, OpenDNS, Sonicwall, Palo Alto, Sophos, Meraki, and Fortinet, and the firm holds Microsoft Gold Partner status alongside partnerships with Barracuda, Veeam, Huntress, Dell, and Tech Data.

Castellan's revenue model blends subscription-based managed IT services (recurring monthly monitoring, maintenance, security, and strategic oversight) with project-based IT consulting and project management engagements for cloud migrations, network upgrades, and infrastructure deployments. Pricing is quote-based and tailored to each client environment with no publicly disclosed tiers, and customer acquisition is driven by direct sales outreach, inbound website and phone inquiries, local SEO targeting LA-area IT services keywords, blog content marketing, and local PR placements in Calabasas Style magazine and Valley Vantage. The company segments its offering horizontally across at least nine industry verticals, including Non-Profit, Marine, Manufacturing, Legal, Insurance, Healthcare, Finance, Distribution, and Construction, with a stated emphasis on long-term partnership-based engagements over transactional work. Castellan has no disclosed funding rounds, no parent company, no subsidiaries, and no completed acquisitions, remaining a bootstrapped regional MSP under the leadership of Managing Partner Mikey Sodetani.
