Key people at Alexander Open Systems.
Alexander Open Systems (AOS) is a Midwest-based IT consulting and systems integration firm founded in 1992, specializing in architecting, implementing, and supporting enterprise technology solutions including networking, unified communications, data center, security, cloud, and managed services.[1][2][4] Headquartered in Overland Park, Kansas, with 10 offices across the Central and Western Midwest, AOS grew to over $220 million in revenue and 400 employees before being acquired in 2017 first by Unitas Global and later integrated into ConvergeOne, a larger IT services provider.[1][2][3] It served enterprises and mid-market clients, particularly in compliance-sensitive sectors like banking, healthcare, and finance, by delivering customized solutions from partners like Cisco and Silver Peak for technologies such as SD-WAN.[1][2]
AOS traces its roots to the Alexander family legacy in IT, starting with grandfather Gary Alexander in sales at Sperry (now Unisys), passing expertise to son Chris Alexander, who co-owned AOS alongside family members Gary, Scott, Thatcher, and Duncan.[3] Founded in 1992 in Overland Park, Kansas, AOS began as a value-added reseller (VAR) and systems integrator focused on consulting, design, implementation, and support for networking solutions like local, wide area, and wireless systems.[1][2][6] Over 25 years, it expanded regionally with a unique Midwest footprint, achieving pivotal growth through deep client relationships in enterprise IT before selling to ConvergeOne in a transaction advised by Lincoln International, with founder Gary Alexander praising the outcome for shareholders and employees.[2]
AOS rode the wave of enterprise IT modernization in the 1990s-2010s, capitalizing on demand for integrated networking, cloud migration, and security amid digital transformation and the rise of SD-WAN, which IHS projected to reach $861 million globally by the mid-2010s.[1] Its timing aligned with enterprises seeking regional providers for complex, compliance-driven deployments in finance and healthcare, where adoption of advanced networking grew despite regulatory hurdles.[1][2] By influencing the Midwest startup and mid-market ecosystem through partnerships and implementations, AOS bridged national tech vendors with local needs, paving the way for family spin-offs like Alexander Cybersecurity Solutions (ACS), which now focuses on revenue-sustaining cyber protections.[3]
Post-acquisition by ConvergeOne, AOS operates as "AOS, a ConvergeOne Company," leveraging expanded resources in cloud, collaboration, and security to pursue larger national deals amid ongoing IT infrastructure upgrades.[2] Trends like escalating cyber threats, hybrid cloud adoption, and AI-driven networking will shape its path, with the Alexander family's ACS extension signaling sustained influence in specialized security.[3] Its legacy as a Midwest IT powerhouse positions it to evolve from regional integrator to key player in enterprise resilience, tying back to its foundational role in delivering reliable tech foundations for business growth.[1][2][3]
