Clinkle

Clinkle was a mobile payments startup founded in 2011 by Lucas Duplan, then a computer science student at Stanford University. The initial concept for the company emerged after Duplan's study abroad program in London, aiming to create a digital wallet that could replace physical ones. The company's journey began in a rented house in Palo Alto, with guidance from a Stanford professor and initial funds from Duplan's parents and a summer program.

The company captured significant attention in June 2013 by securing what was reported as the largest seed funding round in Silicon Valley's history at the time, totaling $25 million. This substantial investment came from a roster of high-profile venture capital firms and individuals, including Andreessen Horowitz, Accel Partners, Peter Thiel, Intel Capital, and Marc Benioff. Despite the massive hype and a waitlist that grew to over 100,000 students, the company remained secretive about its technology, which was rumored to involve high-frequency sound waves for transactions.

Clinkle's initial product promise was a mobile application to facilitate payments without the need for cash, credit cards, or hardware like mobile card readers. The target market was initially college students and nearby merchants. However, the company failed to launch a viable product that matched its ambitious vision. Internal turmoil, including significant layoffs, high executive turnover, and a leadership style from Duplan that was described as problematic, plagued the company's operations. By the time a product did launch in September 2014, it had pivoted away from the original concept. The public offering was a rewards-based debit card called the Clinkle Card, which was a significant departure from the revolutionary payment system initially promised. This pivot failed to gain traction as competitors like Venmo and Apple Pay had already surpassed Clinkle's technological edge. The company eventually pivoted again to a rewards SDK called "Treats" before quietly shutting down in 2016.
