Cloud-based enterprise platform Actiance has raised $28 million in funding from new and existing investors. The additional capital takes the company’s total to more than $43 million.

Participating in the funding round were new investor, Golub Capital, alongside existing investors Credit Suisse NEXT Investors; JK&B Capital; Scale Venture Partners; and Sutter Hill Ventures. The new capital will be used to scale globally by opening new data centers in Frankfort and Amsterdam, and to accelerate product innovation, especially with its Alcatraz solution. Alcatraz is Actiance’s cloud-based archive for email and social media communications, and will be unveiled with new features at the company’s user conference in June 2015.

Golub Capital Managing Director Peter Fair pointed to Actiance’s “strong growth trajectory” in explaining his firm’s investment. “As companies struggle to manage new communication and collaboration channels, they need a solution like Actiance that enables them to fully utilize the channels needed to keep in touch and stay ahead,” Fair said.

Actiance has been busy in recent weeks. The company announced an integration with CellTrust, bringing its secure archiving technology to mobile voice and text. And earlier this month, Actiance announced support for Skype for Business and Yammer.

Founded in 1998 and headquartered in Redwood City, California, Actiance demoed its Socialite technology at FinovateFall 2012 in New York. Kailash Ambani is president and CEO.
