It all started when founder Vijay Balasubramaniyan was traveling in India and tried to order a new suit from a local tailor. His bank flagged the international transaction as suspicious and tried to call him to verify the purchase, but the bank couldn’t prove its identity over the phone. Vijay also had no way to prove his identity to the bank. As the bank cancelled his order, Vijay promised himself he would find a better way for people to authenticate over the phone.


Vijay Balasubramaniyan invents Phoneprinting™ technology

Balasubramaniyan completes his PhD at the Georgia Institute of Technology. His dissertation focused on analyzing the traits of phone calls to determine their true characteristics. He brands this technology “phoneprinting,” creating the trademark, and receives immediate interest from major U.S. banks.


Pindrop is founded

Dr. Mustaque Ahamad sets up a meeting between his former student, Vijay Balasubramaniyan, and local serial entrepreneur Dr. Paul Judge. The three agree to co-found Pindrop with a goal to revolutionize call center security and create a vision for the future of voice.


Pindrop raises $1 million in seed funding

Pindrops initial investors include Andreessen Horowitz, GRA Venture Fund, New World Ventures, Sigma Partners, and Webb Investment Network. The company uses the funds to scale customer acquisition and expand product development, quickly adding marquee clients.


Gartner cites Pindrop for Phoneprinting™ technology

Avivah Litan, Vice President and Distinguished Analyst for Gartner, writes that call centers should “use voice biometrics and phoneprinting (analysis of the originating calling phone) to strengthen user authentication and fraud prevention across multiple channels.”


Pindrop raises $11 million in Series A funding from Andreessen Horowitz & Others

Led by Andreessen Horowitz and Citi Ventures, this round included new investors Redpoint Ventures and Felicis Ventures alongside Webb Investment Network (WIN). The funding allows Pindrop to meet strong customer demand with additional engineering, operations, sales and marketing resources in the U.S., Canada and Europe.


Pindrop releases Fraud Detection System 2.0 which combines Phoneprinting™ technology with voice biometrics

Pindrop releases Fraud Detection System version 2.0, which adds voice biometrics to Pindrop’s then patent-pending Phoneprinting technology. The combination allows Pindrop to help call centers confirm the identity, location, and type of device used for calls into a particular institution or call center.


Pindrop expands globally

Fighting phone fraud, as well as more effectively authenticating customers, becomes a priority for financial institutions globally. In 2014, Pindrop begins working with clients in major financial centers including London and Toronto.


Pindrop closes $35 million investment, one of the largest Series B rounds in the history of the industry

Institutional Venture Partners (IVP) leads the round with reinvestment from existing investors Andreessen Horowitz, Citi Ventures, Felicis Ventures, Redpoint Ventures and Webb Investment Network. This additional investment enables Pindrop to globally expand operations while continuing to improve service to its existing customers.


Patent for Phoneprinting technology granted

USPTO Patent No. 9,037,113 was granted for the algorithm Balasubramaniyan developed to analyze calls in 2011. The patent further solidifies Pindrop’s continued leadership in the fast-growing voice anti-fraud and authentication market, with top banks and retailers as well as Fortune 500 companies deploying Pindrop® technology.


Pindrop Raises $75 million Series C led by CapitalG

CapitalG leads this $75 million Series C funding round with participation from GV, Andreessen Horowitz, IVP, Citi Ventures, and Felicis Ventures, bringing Pindrop’s total funding to $122 million.
