What management had to say

In the company's first-quarter earnings release, CEO Stephane Kasriel called the quarter "a solid start to the year."

Kasriel added: "During the quarter we made significant progress with the launch of several new products, features, and enhancements to support our increasingly diverse and expanding online talent marketplace. We are confident in the strategic initiatives we've set and pleased with our progress against them, as well as the results they're driving."

Looking forward

Upwork left its guidance for full-year adjusted EBITDA the same: between breakeven and 1% of revenue. But management increased the low end of its full-year revenue guidance range, which is now between $299 million and $304 million. Previously, Upwork forecast full-year revenue between $298 million and $304 million. 

For context, Upwork's revenue in 2018 was $253 million. Its adjusted EBITDA was $3.8 million, or about 1% of revenue. 

For its second quarter, Upwork said it expects revenue between $72.5 million and $73.5 million. The midpoint of this range implies 16% year-over-year revenue growth.
