Sigma Solutions was a prominent American IT solutions provider specializing in data center modernization, collaboration tools, and cloud computing services. Founded in 1992 and headquartered in San Antonio, Texas, the company built a strong reputation for delivering complex technology solutions to a diverse clientele across various industries. In May 2017, Sigma Solutions was acquired by ConvergeOne (NASDAQ: CVON), a leading global IT services provider. While Sigma Solutions now operates as an integral part of ConvergeOne, its legacy of technical expertise, customer-centric service, and regional market presence continues to contribute to ConvergeOne's expanded portfolio and capabilities. This page provides historical information about Sigma Solutions as an independent entity prior to its acquisition.
The headquarters served as the central hub for all corporate operations, including executive leadership, sales management, engineering, solution design, and administrative functions.
While specific architectural details are not widely publicized, as a technology solutions provider, the facility likely included advanced IT infrastructure, potentially demonstration labs for client solutions, and collaborative workspaces.
Sigma Solutions was known for a customer-focused and technically proficient work culture. It emphasized teamwork, innovation in delivering IT solutions, and strong relationships with technology partners and clients.
The San Antonio headquarters was strategically important as the command center for a leading regional IT solutions provider in the Southern United States, driving its growth, operational excellence, and market expansion before its integration into ConvergeOne.
Prior to its 2017 acquisition by ConvergeOne, Sigma Solutions primarily operated within the United States. Its main focus was on serving domestic clients, with a particularly strong presence in Texas, Louisiana, Oklahoma, and Arkansas. The company specialized in providing data center, collaboration, and cloud solutions to North American businesses. Sigma Solutions did not maintain a significant independent global office network; its international reach and capabilities were greatly expanded following its integration into ConvergeOne's global operations.
