Clinkle
The business, the turning points, and the decisions behind them.
01 / WHAT IT BUILT
What the company did
Clinkle was a mobile payments startup founded in 2011 by 22-year-old Stanford graduate Lucas Duplan. Its original product aimed to let smartphones pay each other using ultrasonic signals, removing the need for credit cards or NFC. After the ultrasonic approach failed, the company pivoted in 2014 to a prepaid debit card with a lottery-style rewards program called Treats, and later to a Treats referral-rewards SDK for other apps. It never achieved meaningful traction and shut down around 2016.
02 / Clinkle FAILURE REASONS
Failure reasons
Clinkle abandoned its original ultrasonic payments technology after running into insurmountable technical challenges, and its replacement prepaid debit card with gamified rewards failed to win users. The company was consumed by internal turmoil: it laid off nearly a quarter of its staff, lost its COO Barry McCarthy and other high-profile hires, and saw seven employees quit in a single day in May 2015 in protest of CEO Lucas Duplan's management. Despite a then-record $30 million in seed funding from backers including Peter Thiel, Marc Benioff and Richard Branson, it never shipped a product anyone wanted.
