Other B2B Software · Spartanburg, United States · Founded 2002
OpSource, established in May 2002 by co-founders Michael Piacente, Dan Rasmussen, John Rowell (CTO), and Treb Ryan (CEO), carved out a niche in the cloud and managed services sector from its headquarters in Santa Clara, California. The firm initially provided application support for major clients like Microsoft's Hotmail before strategically pivoting to the burgeoning Software-as-a-Service (SaaS) market around 2005. This move allowed OpSource to support Independent Software Vendors (ISVs) in development, marketing, and sales, effectively helping them transition to a SaaS model.
The company's business model rested on two primary offerings: managed hosting and cloud computing. The managed hosting service, a dedicated solution with support for various applications and operating systems, guaranteed 100% uptime for hosted applications. Its cloud computing service was delivered as Infrastructure-as-a-Service (IaaS), operating on a utility-based, pay-as-you-go model that allowed clients to rent resources, thereby avoiding significant capital expenditure. This dual offering enabled customers to blend dedicated environments with flexible cloud services to meet complex IT demands. Over its history, the company served more than 600 enterprises, service providers, and SaaS ISVs.
A significant milestone was the acquisition of Dublin-based Lecayla Technologies in 2008, which added sophisticated metering and billing services to its portfolio. The company's growth was fueled by $56.5 million in funding from notable investors including Intel Capital and NTT. This journey culminated on June 30, 2011, when OpSource was acquired by Dimension Data, a subsidiary of NTT Holdings, for an undisclosed amount. The acquisition was a strategic move by Dimension Data to accelerate its cloud service offerings, integrating OpSource into a newly formed Cloud Solutions Business Unit. Following the acquisition, the OpSource brand and its services were absorbed into what became Dimension Data Cloud.
