Digital innovation agency Robots & Pencils has sold its Missions application to Slack. Terms of the deal weren’t disclosed. Missions enables Slack users to create workflows that automate common company processes. Robots & Pencils, which is based in Canada but has its U.S. base in Cleveland, said in a statement that personnel from the team that built Missions are now going to Slack as employees. However, despite their exit, Robots & Pencils says it’s leaving the door opened for the Missions team members to remain part of the R&P family in an advisory, voluntary role as “Fellows,” where they can influence areas of interest to them, and the door will always stay open to them if they ever want to return. “We built Missions because we care about helping people work together across all parts of a business, not just within IT,” Missions co-founder and CEO Mike Brevoort said in a statement. “We’ve believed for a long time that the collaboration hub model is the future of work, and by joining Slack, we’re able to massively scale up this vision and our impact on teams at work.” For their part, Slack gets into some detail about its plans for Missions, which you can read here. Robots & Pencils merged with Cleveland-based Kinetiq Digital in January 2017. It works with more than 175 clients to create over mobile solutions used by 77 million people worldwide.
