Artificial intelligence may be all the craze in Silicon Valley, but on Wall Street, well, theres a lot of skepticism.

High-powered algorithms are not a new phenomenon in finance, and for this industry, the name of the game is efficiency and precision.

Quite frankly, finance executives want systems that, in one way or another, make money. Because of this, new wild and flashy AI systems that just make something smart wont fly.

The fintech companies that are successfully leveraging AI today are the ones that have found a very concrete way to apply the technology to an existing business problem. For example, technology such as specialized hardware, big data analytics, and machine learning algorithms are being used in fintech to augment tasks that people already perform.

At the Singularity University Exponential Finance Summit this week, Neil Jacobstein, faculty chair of Artificial Intelligence and Robotics at SU, shared some of the most interesting AI companies in fintech right now.

Not surprisingly, these companies each have a clear market application and reduce friction in the business problems they address.

CollectAI is a cloud-based software system thats shaking up the collection business. The system is able to mimic the voice and tone of a collection agent to gather important information over the phone about a collections case.
