Pindrop Security specializes in finding and stopping phone fraudsters who prey on call centers and banks. Now, with an $11 million round of funding led by Andreessen Horowitz, the startup hopes to expand its efforts around the globe.
What Pindrop does is actually interesting. It uses a technique called Acoustic Fingerprinting to identify fraudsters, their locations, and their devices and then adds that data to a huge store of records. This database, called CallDNA, helps to sort the legitimate from the malicious callers. The company says it can pinpoint 80 percent of would-be attackers on their first call.
