Sierra-Atlantic was a global IT services and outsourcing company headquartered in Fremont, California. Founded in 1993, it specialized in enterprise applications (such as Oracle and SAP), software development, quality assurance, and IT consulting. The company had a significant offshore presence, particularly in India and China, enabling it to provide cost-effective solutions to clients across various industries including high-tech, manufacturing, retail, and financial services. In December 2010, Sierra-Atlantic was acquired by Hitachi Consulting, which was later integrated into Hitachi Vantara. The acquisition aimed to strengthen Hitachi Consulting's global delivery capabilities and expand its service offerings.
Served as the global corporate headquarters, housing executive leadership, strategic planning, sales, marketing, and administrative functions for North American and global operations.
Likely a modern office facility within a business park, typical of tech companies in the Silicon Valley area, designed to support collaboration and client engagement.
Reportedly fostered a dynamic, client-centric, and results-driven environment. Emphasized global collaboration given its significant offshore delivery centers. Innovation in IT solutions and service delivery was a key cultural aspect.
The Fremont headquarters was central to Sierra-Atlantic's growth strategy, its access to Silicon Valley talent and venture capital, and its coordination of worldwide operations before its acquisition by Hitachi Consulting.
Prior to its acquisition by Hitachi Consulting in 2010, Sierra-Atlantic had a significant global presence. Its operations were anchored by its headquarters in Fremont, California (USA), and major global delivery centers in Hyderabad and Bangalore (India), and Guangzhou (China). They also maintained sales and support offices in various locations across North America, Europe, and Asia-Pacific to serve a global clientele. This network enabled them to provide 24/7 support and deliver complex IT projects by leveraging talent and resources across different time zones.
