Waltham's Actifio retains 'unicorn' status with $100M round

Waltham-based data management firm Actifio Inc., already one of the most valuable private tech companies in Massachusetts, has raised another $100 million at a valuation of $1.3 billion.

The new funding on Tuesday maintains Actifio’s status as a “unicorn,” a privately held company valued at over $1 billion. The financing comes from Crestline Investors, a Texas-based investment firm that says it specializes in credit and “opportunistic investments.” Previous investors like North Bridge Venture Partners, 83North, Advanced Technology Ventures, Heritage Group and Andreessen Horowitz also participated.

The $1.3 billion valuation represents a bump from the $1 billion mark that investors attached to Actifio during a $100 million fundraising in 2014. Actifio has now raised more than $300 million since its founding in 2009.
