Dropbox has made another acquisition: Predictive Edge, a startup that had built a way to personalize e-commerce offerings, along with dynamic pricing, for marketers to send out to users and run A/B tests around them. The service will be shut down, and the founders will be working on something different, as they note in an announcement on the site: “Predictive Edge is joining forces with Dropbox!,” the company writes. “Going forward we’ll be focused on solving problems outside the world of A/B testing. As of today, you can no longer sign-up for our service, and we’ve informed current customers that our product will no longer be supported. Many thanks to you all for your feedback & support, and here’s to a new chapter!”
