Slack App - Review of the Top Software Startups



Slack App offers chatting and communication with a business focus. Unlike apps that are more targeted to social media, Slack is about helping employees and businesses communicate with one another. As of March 2015, the company was valued at $2.76 billion, and it continues to grow. In the course of six months, the company has more than doubled its valuation. The explosive growth of the company has come from the addition of an average of $1 million in new contracts every 11 days, and from $12 million in recurring revenue from the previous year.

In just one year, Slack App has grown to hundreds of thousands of daily users. It has been deemed the fastest–growing business app ever. The reason Slack has experienced such phenomenal growth is because it did something the other app companies did not: It worked with the business app as though it was a consumer app. The gap traditionally seen between business and consumer apps has been shrinking, and Slack has taken advantage of this opportunity.

Slack’s timing was impeccable. Many businesses were disenchanted with the options they had for connecting with co–workers on a business level. With the Slack app, smaller teams throughout various companies discovered it in the cloud and started to use it. Quickly, Slack has become many companies’ first line of communication. 

In the beginning, there was almost no marketing done by Slack. The app sold itself, as people discovered it and word–of–mouth advertising caused more people to start using it. Because it provided employees with exactly what they needed and wanted in a business communication app, they told everyone they knew about it. That meant a more organic adoption of the service, and a higher level of loyalty from the user base. What made Slack so popular, though, was Twitter.

Businesspeople who used and loved the app would make mention of Slack on Twitter, where all their followers would see it. That led many more people to try the app, to see what the buzz was all about. CEO Stewart Butterfield believes that the app may not have seen such a high level of success so quickly if it was not for Twitter and all the people mentioning Slack on the social media platform. That was not the only reason the Slack app became so popular so quickly, though. Another reason was its ease of use, which is important to businesspeople who don't have a lot of time to learn yet another new piece of technology.

The layout of the Slack app is intuitive, and it integrates seamlessly with hundreds of other apps, so the information from them can be pulled into Slack. There is no training needed to start using the app, and the ease of customization makes the app a hit with people in all different types of businesses. If they need communication that's fast, easy, and well–prepared to work with other apps and technology, they need Slack – and thanks to the buzz around the app, they know it.  Will Slack be acquired by LinkedIn, Microsoft, or Google?  Only time will tell.
