Haydn Sonnad (born 1999) is an American entrepreneur based in Calabasas, California. He is best known as the founder of Tesloop, which he founded in 2015.

Sonnad came up with the idea of Tesloop when he got his driver's license at age 16. He got his father Rahul Sonnad and three co-founders onboard to get Tesloop off the ground. Tesloop would initially offer users ride-sharing from Los Angeles, California to Las Vegas.

Over the next three years, Tesloop had built a customer base of 25,000 to 30,000 on its rides from Los Angeles to Las Vegas, Palm Springs, and San Diego.

In October 2018, Haydn and his team ceased operations of Tesloop to focus on building Carmiq.

The goal for Carmiq is to be the world's first connected electric vehicle /hybrid multi-sided marketplace for data driven services such as insurance, maintenance, and financing.
