What Happened to Tiny Speck?

Tiny Speck was founded in 2009 by Stewart Butterfield, Eric Costello, Cal Henderson, and Serguei Mourachov, many of whom were also co-founders of the popular photo-sharing site Flickr. The company, with principal offices in Vancouver and San Francisco, initially set out to create a unique browser-based massively multiplayer online game (MMO) called Glitch. The game was characterized by its focus on creativity, collaboration, and a whimsical 2D art style, rather than combat. Tiny Speck secured significant early funding, including $1.5 million in angel funding in 2009, followed by a $5 million Series A in 2010 and a $10.7 million Series B in 2011, totaling over $17 million to develop Glitch.

Despite the investment and a passionate development team, Glitch struggled to find a broad enough audience to be financially viable. It officially launched on September 27, 2011, but quickly reverted to beta status on November 30, 2011, citing issues with accessibility and depth. Ultimately, Tiny Speck announced the permanent shutdown of Glitch on December 9, 2012. The game's closure was attributed to its inability to attract a critical mass of players and its reliance on Adobe Flash technology, which was becoming outdated and poorly adapted for mobile platforms.

The failure of Glitch, however, led to one of the most successful pivots in tech history. During the development of the game, the Tiny Speck team had built an internal communication tool to streamline their own collaboration across different locations and time zones. Recognizing the effectiveness of this tool and the widespread challenges in workplace communication, the company decided to shift its focus entirely. In late 2012, with approximately $5.5 million of their initial funding remaining, Butterfield convinced investors to support the pivot towards commercializing this internal tool, which was named Slack (an acronym for 'Searchable Log of All Communication and Knowledge').

Slack launched its private beta in August 2013 and officially exited beta on February 12, 2014. It quickly gained traction due to its user-friendly interface, robust search capabilities, and extensive integration with other business applications. The platform experienced rapid growth, reaching unicorn status in 2014. On June 20, 2019, Slack Technologies went public on the New York Stock Exchange through a direct listing under the ticker 'WORK,' achieving an initial market valuation of approximately $19.5 billion.

The company's success culminated in its acquisition by Salesforce. On December 1, 2020, Salesforce announced its intent to acquire Slack for $27.7 billion, a deal that closed on July 21, 2021. This acquisition was Salesforce's largest to date, aimed at integrating Slack's communication capabilities into its Customer 360 platform and strengthening its position against competitors like Microsoft Teams.

As of October 1, 2026, Slack operates as a subsidiary within Salesforce, forming a core component of its 'Agentforce 360 Platform, Slack and Other' segment. Slack continues to be a leading enterprise communication tool, with an estimated 47.2 million daily active users and 79 million monthly active users in 2025/2026. Salesforce has continued to invest heavily in Slack, announcing 30 new AI features in March 2026 and planning for automatic provisioning of Slack for all new Salesforce customers starting in Summer 2026. Recent updates in September 2026 include enhanced activity filters, passkey sign-in, and customizable sidebar tabs, demonstrating ongoing development and integration within the Salesforce ecosystem. Slack's revenue is projected to reach approximately $3 billion for fiscal year 2026.
