Today, we are thrilled to announce that TapEngage has been acquired by Dropbox. We’re still working with the Dropbox team to determine next steps for TapEngage, but we wanted to give our clients and partners the update. We owe a debt of gratitude to our partners, investors, and friends —we couldn’t have done it without your support! We’re more excited than ever about the mobile space and can’t wait to show you the things we’ll be working on at Dropbox.
