BufferBox was founded by three engineering students at the University of Waterloo. It was acquired by Google for a reported $17 million or more. The company solves the problem of failed parcel deliveries by leveraging automated, self-serve locker kiosks.
GOINSTANT ACQUIRED BY SALESFORCE
Halifax's GoInstant emerged from stealth at TechCrunch Disrupt in late 2011. It was acquired by Salesforce for $70 million. The company provides smooth, real-time co-browsing of the web, among other features.
SUMMIFY ACQUIRED BY TWITTER
