Zomato's Co-founder and Chief Technology Officer (CTO) Gunjan Patidar tendered his resignation on Monday. "Gunjan Patidar was one of the first few employees of Zomato and built the core tech systems for the company. Over the last ten plus years, he also nurtured a stellar tech leadership team," Zomato said. Another Zomato Co-founder Mohit Gupta quit in November last year.
