Uber Technologies Inc.'s revenue increased to $3.4 billion in the first quarter and losses narrowed, even as hundreds of thousands of people deleted the company's ride-hailing app from their phones.

The company also said its head of finance, Gautam Gupta, is leaving. Gupta, who has long served as 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. Uber said it's now searching for a true CFO who can woo Wall Street.

Uber has faced a series of public relations crises this year. The hashtag #DeleteUber trended on Twitter as users removed the application from their phones in protest of the company's ties to U.S. President Donald Trump. CEO Travis Kalanick left Trump's business advisory board in response. Then, after Bloomberg published a video of Kalanick arguing with an Uber driver, the embattled CEO said he would seek leadership help. The company is searching for a chief operating officer and fending off a lawsuit from Alphabet Inc. over driverless-car technology.
