Uber’s de-facto Chief Financial Officer Gautam Gupta has resigned from the company. He is going to depart Uber in July to take on a new responsibility as a Chief Operating Officer at a newer startup in San Francisco. Uber is on a lookout for a Finance Head. 

Gupta, who has long served as a de facto chief financial officer even though he never earned the title, helped oversee investor calls and run the finance team. But there had been persistent questions from employees and investors about whether he had the experience to lead Uber through an eventual initial public offering, according to a media report.

Uber’s Founder and Chief Executive Officer, Travis Kalanick said in a statement, "Over the last four years, (Gupta) has been indispensable in helping build Uber from an idea into the business it is today.” 

Uber in its recent quarterly report has narrowed their loss on rising revenues. The company said that its revenue during the first three months of this year rose some 18 percent to $3.4 billion, but the company logged a loss of $708 million without taking into account stock compensation for employees.

And this success was attributed to Gautam by Kalanick. He said, "We couldn't have done it without him, and I will miss his energy, focus and infectious enthusiasm."

Uber has been going through a lot of bad press owing to senior exits, difficult people practices, sexual harassment case, and video grab showing Kalanick in a verbal argument with one of Uber’s drivers. Company's President Jeff Jones quit in March this year less than seven months of his joining.

More recently, the company had to fire an engineer accused in a trade secrets suit involving files he purportedly purloined from Alphabet's self-driving car unit Waymo.

The WSJ first reported the news on Wednesday.
