San Francisco-based Slack, an online platform businesses use for instant messaging, is looking for about 50,000 square feet of office space around downtown, according to several sources familiar with the company’s search.
Many tech companies use Slack for managing workflow, including Airbnb, Pinterest and Pandora.
Customers can use Slack for free, or pay $6.67 per month per active user or $12.50 per month per active user, depending on added features.
Founded in 2009 in San Francisco, the startup has raised $790 million in funding, according to Crunchbase. It has 9 million weekly users, according to its website.
In addition to San Francisco, Slack has offices in New York, Vancouver, London, Toronto, Dublin, Melbourne and Tokyo.
It joins a growing list of San Francisco tech firms looking around downtown for office space. This week, cycling and running app Strava checked into space at Galvanize on Platte Street.
Slack did not return requests for comment.
