Whatever they're putting in Actifio's water, we'd like some too. Sheesh!

Four years after picking up a $100m E-round, data wrangling biz Actifio has picked up another $100m in an F-round.

Its total funding to date stands at $311.5m, with a $1.3bn valuation, making this US biz a standard-issue tech unicorn, according to our records. The latest round was led by Crestline Investors, which was joined by North Bridge Venture Partners, 83North, Advanced Technology Ventures, Heritage Group, Andreessen Horowitz, and other existing investors.

Back in the 2014 E-round days, Actifio’s valuation was $1.1bn. It was rumored to be preparing for an IPO, and was expecting to achieve a $100m annual revenue run-rate that year. The IPO never happened and, in four years, its valuation has increased by just $200m. Somehow, somewhere, it ran out of steam.
