Sandy-based IT consulting firm Open Communications LLC has been purchased by Upstack, a platform that transforms the architecture and sourcing experience for businesses seeking cloud and Internet infrastructure solutions. Upstack is headquartered in New York City.

Founded in 2012, Open Communications specializes in network, contact center as a service (CCaaS) and unified communications as a service (UCaaS) for businesses of all sizes. The terms of the transaction were not disclosed.

Upstack said its acquisition of Open Communications is part of its strategy to accelerate the growth of its platform, which combines leading Internet infrastructure advisors with proprietary software and dedicated support resources. The growth strategy is supported by a $50 million equity investment from Berkshire Partners, which will enable Upstack to continue to scale its platform through technology expansion and partner acquisitions.

As part of the deal, Open Communications founder Amanda Heinritz will join Upstack as a partner and an equity stakeholder. She will serve as an advisor to business customers that are sourcing data center, colocation, cloud, network connectivity and other technology solutions through the Upstack platform.

“Open Communications is an exciting addition to Upstack,” said Christopher Trapp, CEO of the company. “Amanda and her team have grown Open Communications steadily through their hard-earned relationships and vast referral network. Upstack gives them the platform and processes to grow even faster. We look forward to working together.”

“Upstack not only had a clear understanding of what my business is and how much it’s worth, but provided a game-changing technology platform that literally cuts out five steps of our sales process, saving my team tons of time,” said Heinritz.
