Slack rakes in $427 million in series H funding

Slack, the San Francisco-based start-up offering collaboration apps and services, announced $427 million in a series H funding round. The company has previously raised $827 million in its previous funding rounds. The company says the new level of investment reflects a post-money valuation of more than $7.1 billion.

Slack claims more than 8 million Daily Active Users (DAUs) and more than 70,000 paid teams

The Series H equity round was led by Dragoneer Investment Group and General Atlantic, joined by funds and accounts advised by T. Rowe Price Associates, Inc. and funds advised by Wellington Management, and Baillie Gifford and Sands Capital, as well as existing investors.
