Co-founder of online food delivery platform Zomato Gaurav Gupta, a key figure in the run-up to the company's IPO in July, has resigned.

In an email sent to staff at Zomato, Gupta - who was the head of supply - said he will be starting a new chapter after spending six years at the company. "I am taking a new turn in my life and will be starting a new chapter, taking a lot from this defining chapter of my life - the last 6 years at Zomato. We have a great team now to take Zomato forward, and it's time for me to take an alternate path in my journey," Gupta said.
