Pindrop is a fraud-detection service that call centers are using to secure their phone communications. Using special patented Phoneprinting technology, Pindrop is able to identify, locate, and authenticate callers. This unique service has become so popular that Business Insider recently named Pindrop one of the hottest under-the-radar startups of 2017.

What makes it so hot? The fact that it’s being used by some of the world’s largest banks, brokerages, insurers, and retailers. This type of a service has an enormous market, considering that it saves companies millions of dollars every year in averted fraud losses.

In fact, according to a Pindrop case study, call centers in the U.S. spend more than $10 billion each year validating callers. In one instance, Pindrop’s advanced fraud detection system saved their brokerage client $1.5 million.

Due to the success and popularity of the service, Pindrop has already attracted the likes of elite investors. To date, the company has raised $122 million in funding from Andreessen Horowitz, CapitalG, GV, Felicis Ventures, among many others.
