Recent Developments

In December 2015, Slack announced an $80M fund backed by Slack and six of our investors with the goal of helping ISVs build apps to take advantage of the Slack platform. In addition it rolled out a new framework for Slack development called Botkit by Howdy, simplifying the creation of apps (especially bots) with a flexible codebase that handles things like authenticating apps to a team and the sending, receiving, and processing of messages with Slack API. Already more than 160 apps in Slack App Directory are available extending the power of the Slack platform.

SCORES Analysis

Slack Strengths

Slack provides a messaging platform that integrates with and unifies a wide range of communications services such as Twitter, Dropbox, Google Docs, Jira, GitHub, MailChimp, Trello, and Stripe. Since its beginning in 2013, Slack has taken the team collaboration market by storm - basically reinventing how team work is communicated, defined and accomplished through constant swapping, searching and making sense of hundreds of millions of messages being sent back and forth.


In 2014 its first year of making its Cloud service available to the public, Slack signed more than 135,000 paid accounts, which pay anywhere from $8 per user per month to $15. Small companies to big organizations such as Adobe, LiveNation and New York Times have signed on as customers.


By March 2015, Slack announced that it was picking up $1 million in new annual recurring revenue every 11 days. Its dizzying growth has also been fueled by a war chest of $340 million in funding that has been raised to date. No question about it, there is nothing lacking in the world of Slack.
