UPSTACK, the fastest-growing advisory platform for digital infrastructure, has acquired NPG Solutions LLC, an independent technology and communications solutions adviser based in New Albany, Ohio. The terms of the transaction were not disclosed. NPG Solutions is UPSTACK's 25th partner investment in the past two years.

As part of UPSTACK's investment, NPG Solutions' owners and managing partners, Bill Fuller and Bob Ray, will join UPSTACK as Partners.

Founded in 2009, NPG Solutions provides network, data center, cloud and security services to businesses of all sizes and industries, focusing on global companies in manufacturing, health care and finance. NPG Solutions provides supplier sourcing and management through its 10-step SmartSource process, which leverages the company's proprietary SmartSpendIT supplier management tool to analyze customer needs, vet suppliers, and select and manage solutions.

"NPG was one of the first telecom agencies to realize the benefits of pairing expert advisory services with sourcing and management software," said UPSTACK Founder and CEO Christopher Trapp. "NPG's vision in developing proprietary tools to scale and improve client services aligns perfectly with UPSTACK's, making NPG a great fit for our organization. We're excited to welcome Bill and Bob to the UPSTACK team as our milestone 25th partner investment."
