Eventually, Tiny Speck rebranded as Slack Technologies, and its new flagship product was launched to the world. In August 2013, when Slack debuted, 8,000 companies signed up to the wait list to try the product. Within two weeks, this grew to 15,000. By the next year, Slack would have 135,0000 paying subscribers and 10,000 new users signing up per day. Soon after that, a million daily active users, then two, then three, and so on. Stewart and the company—now 100 percent focused on Slack—would raise their next round in April 2014, fully completing their transition.
