A.I. start-up Petuum is the latest company to get a big check from SoftBank

Enterprise tech start-up Petuum is on a quest to help businesses of any kind use artificial intelligence just like Google, Amazon, Facebook or Tesla. Companies can use AI to build recommendation systems, help diagnose diseases and add self-driving capability to cars, according to Petuum co-founder, CEO and chief scientist Eric Xing, a computer science professor now on sabbatical from Carnegie Mellon University. Now the start-up has raised $93 million in a new round of venture funding from SoftBank to develop and popularize this technology, Xing told CNBC. Most organizations that want to use AI don't have access to a deep bench of technical talent. Nor do they have the computing infrastructure to run AI workloads at scale.
