Workplace collaboration platform Slack has been a runaway success since opening for business just over a year ago: the company co-founded and led by Flickr founder Stewart Butterfield now has 1.1 million daily active users, with 300,000 of them paying for premium tiers of the service bringing in annual recurring revenue of $25 million. Now, Slack is stepping up its game and getting more serious about how it builds out its wider ecosystem. April Underwood — a longtime director of product at Twitter — has been appointed Slack’s first head of platform, a new role at the company.

During my talk on Slack at CALIcon15 someone asked why I was putting my internal communication eggs into a basket that may b be home in a year. I replied that I thought Slack would be around next year and for years to come. This move seems to support my position.
