DSET Corporation

In 1989, James K. Chang and S. Daniel Shia founded DSET Corporation in Norcross, Georgia. Their venture focused on a critical, yet often unseen, part of the telecommunications world: operational support systems (OSS). DSET developed software that enabled telecom carriers and equipment vendors to manage complex network functions, essentially acting as a digital plumbing provider for the industry. As the telecommunications landscape grew more complex, DSET's role as a software and services vendor became increasingly important. The company provided essential tools like OSS gateways and network solutions that powered the burgeoning telecom sector. In 1995, the company secured a private equity investment from Summit Partners, signaling a period of growth. A significant chapter in DSET's journey began in late 2002 when NE Technologies initiated a merger agreement to acquire the company. This move was part of a larger consolidation trend within the telecom software industry. The story reached its conclusion on March 1, 2014, when DSET was officially acquired by Neustar, a major player in information services and technology. The acquisition marked the end of DSET's independent run, integrating its specialized tools into Neustar's broader portfolio.
