Unify Square CEO Sonu Aggarwal.

Unify Square is raising more cash to support its platform that helps clients manage their Skype for Business products. The nine-year-old company just reeled in a $3.9 million round from existing investors, pushing total funding to date past $33 million.

Unify Square is a longtime partner of Microsoft, where CEO and founder Sonu Aggarwal once worked on the product roadmap and development for Live Communications Server and Office Communications Server – projects that would precede Lync, or what is now known as Skype for Business.

The company offers technology that allows clients to monitor and manage Skype for Business, and particularly with enterprise hybrid cloud/on-premise environments.

The fresh cash will be used to grow the company’s product offerings, as well as helping customers transition to Skype for Business Online, which is part of Microsoft’s Office 365 cloud-based service. Unify Square counts Microsoft, Bridge Bank, and Stanford University as investors, among others.

Skype for Business announced updates earlier this week that adds live captions with translations in 40 languages, a “Skype Operations Framework,” and more.
