Uber would not exist without Travis Kalanick.

He wasn't the one to come up with the idea for it or even its first CEO. But there's no doubt that Kalanick was the one to take the company from a seed of an idea for a car service and to craft it into the most valuable private technology "startup" — if you can even call it that — that it is today.

Often, that meant springing into battle against whatever stood in the company's way, whether it was the "a**hole named taxi," as Kalanick once referred to his foes in the taxi industry, or the city regulators that have tried to block his business at every turn.

Kalanick's aggression, dedication, and scrappiness built Uber. But now those same traits threaten to tear it down.

In the last week alone, Uber was the subject of a former engineer's high-profile allegations of sexual harassment and a subsequent New York Times investigation detailing a litany of ugly behavior. The company was publicly rebuked by one of its most famous investors, and then accused of using stolen technology, and sued, by another big investor.

That's a bad week for any company, but for Uber the string of challenges has exposed a dangerous reality that threatens to derail the $69 billion company's path to an IPO: The company no longer enjoys the benefit of the doubt from many of its customers, the media or the general public.

Given the fractured state of the company's reputation, this could well be the tipping point

A big reason for that is because of the reputation it's earned over the years under Kalanick's leadership, and some observers now believe any resolution to Uber's current crisis will have to involve a change with the 40-year-old Kalanick.

"If I were on the board, I would find a way to get rid of him," said Michael Barnett, a business and management professor at Rutgers University. That may not be a realistic scenario in the eyes of many industry insiders, but it's clear that the company has to make some kind of change if it wants to regain the credibility it needs for the business to continue to thrive.

A compounding crisis

This isn't the first time Uber's faced a string of corporate public relations disasters, but it's the first time it's brought the company to a tipping point.

Twice in the last month the company has had to update the automated messages it sends users when they delete their accounts, appending special entreaties asking for forgiveness. The first was during the #DeleteUber movement when more than 200,000 people deleted their accounts in a weekend — an uptick so dramatic that Uber had to build an entirely new system to handle it. This past week, Uber had to update the message again to tell users just how badly it was hurting in wake of the accusations of a sexist work culture at the company.
