The goal: double its users in 12 months.

Project tracking startup Trello has officially reached the 10 million-user milestone for its free service, used by teams at Freshdirect, Google, Kickstarter, and Tumblr.

It wants to double that number over the next 12 months by creating links between Trello’s visual planning and brainstorming app and other widely used collaboration cloud services.

Initially, that list will include Box BOX , Dropbox, Evernote, Github, Google Drive, Google Hangouts, Help Scout, Mailchimp, Salesforce CRM , Slack, and Twitter TWTR .

The catch is that they’ll need to opt for the company’s paid service, called Trello Business Class, to get those features. The starting price is $10 per user, per month.

“This is a first pass at building out integrations with tools that our customers are using,” Trello CEO Michael Pryor told Fortune.

You can think of Trello as a digital whiteboard, where teams can brainstorm and manage projects or processes. Contributors can post updates, set deadlines, comment on solutions to issues, and so forth. Trello has been used to manage everything from home improvements or weddings to software developments.

The new integrations, called “Power-Ups,” let teams manage boards using other software applications they use on a daily basis. For example, you could use the Slack messaging tool to remind project board contributors to report status at a certain tim. Or Trello could be used to visualize the “bigger picture” for a sales pipeline in the Sales Cloud. Those are just two examples.

Trello’s software was originally created as an internal tracking tool by New York-based Fog Creek Software. It was spun off in July 2014, with $10.3 million in funding from Spark Capital and Index Ventures.

Since its initial launch, Trello has localized its service for Brazil, Germany, and Spain. The next stop is France, and Japan is on the priority list.
