Many companies from emerging startups to conglomerates began to use collaboration tools to facilitate internal communication from 2014. Definitely, those tools increase productivity by reducing emails and meetings, sharing the right files immediately and staying looped among teammates.
More than anything else, let’s look at the fatest growing player, Slack. It got a $1 billion valuation in just 8 months after launching publicly in February 2014. It was listed on the New York Stock Exchange at the value of around $20 billion in June 2019. Its daily active user count has crossed over 12 million in Oct 2019. In addition to Slack, there are more than hundreds of collaboration tools and a few unicorns such as monday.com and Symphony. They are doing fairly well.
Recently they are aggressively extending to conventional public and private clients including banks, manufacturers, governments, hospitals, etc. while opening more sales offices in the U.S., Europe, and Asian countries. There are still enormous business opportunities. The market looks promising.
