Mr Khosrowshahi began reigning in costs after he took over as Uber chief late past year, replacing ousted co-founder Travis Kalanick.
Uber Technologies had a painful 2017, but the business managed to grow.
Despite it being a turbulent year Uber, sales reached $7.5 billion.
Uber is looking to partner with autonomous-vehicle companies, the CEO said, adding that the company is prepared to slowly integrate autonomous vehicles in its network filled with human drivers.
In his appearance, Khosrowshahi said Uber could quickly reverse its losses by retreating from less-developed markets outside the US and reducing the money it pours into expensive projects like its work on self-driving cars. Revenue during that stretched climbed about 14 percent to $11.1 billion from $9 billion.
Still, in the fourth quarter, which was the first full reporting period under the control of Dara Khosrowshahi as CEO, Uber's loss shrank to 1.1 billion United States dollars from 1.46 billion USD in the third quarter.
Kanye West returns to Instagram after social media silence
This is the first time West has posted on social media-including Instagram and Twitter-since last May when he totally wiped his accounts.
Khosrowshahi said previously he wants to take the company public by 2019, which means Uber eventually will have to pull back the curtain on details of its financial performance.
Uber is not required to publicly report its financial results, but has begun disclosing some figures in recent months.
Gross revenue for Q4 sits at close to $11.1bn, an increase of close to $1.4bn over Q3 of 2017 and almost double that of the final quarter of 2016, which saw the company report $6.9bn in revenue.

Ride-share titan Uber on Tuesday revealed that its losses previous year swelled despite signs in the final three months that it was stemming the red ink. Uber's loss is based on generally accepted accounting principles, which includes writedowns, as well as the company's enormous legal expenses, such as the cost of defending against a trade secrets lawsuit from Alphabet's Waymo.
Waymo and Uber last week announced a settlement in a blockbuster lawsuit over allegedly stolen trade secrets from the former Google self-driving auto project.
