But this year, investors and big tech companies alike treated workplace messaging as the next big thing.
Slack announced a 0 million investment in September from Japanese tech company Soft Bank, bringing its total funding to 0 million and boosting its valuation from .8 billion to .1.
In June, rumors surfaced that Amazon wanted to buy the company for as much billion.
Meanwhile, Microsoft launched a new chat app called Teams that will eventually replace Skype for Business.
Underwood says that within minutes of launching the Slack app directory in 2015, developers told her they already had customers. Video conferencing company Twine Labs, which Slack invested in, is also building apps for Microsoft Teams, Facebook Workplace, and Amazon Chime, says CEO Anthony Claudia.
It may seem weird to pour so much money into old-hat tech.In addition to Teams, which competes directly with Slack, it offers Microsoft Bot Framework, a platform for building chat-based apps that can run not just on Teams, but on Slack, Facebook Messenger, and other instant messaging services. Microsoft bundles Teams with the Office 365 for no extra cost, and the company announced earlier this year that 125,000 organizations use the software.Even if your company picks another tool for messaging, Microsoft wants to be the technology that underpins the apps you end up using. In October, Facebook announced 14,000 organizations are using Workplace.Product datasheet Upgrade Price Guarantee Compatible with Windows 10, 8.1, 8, 7, Vista and XP, 32 Bit / 64 Bit Editions New language versions: Chinese - Lithuanian - Japanese - Polski - Romanian - Spanish - Czech Update Star is compatible with Windows platforms.Update Star has been tested to meet all of the technical requirements to be compatible with Windows 10, 8.1, Windows 8, Windows 7, Windows Vista, Windows Server 2003, 2008, and Windows XP, 32 bit and 64 bit editions.
