For WeWork, one of the most important measures of its success is its breakneck growth — even if that means huge losses.

The co-working company disclosed on Monday that its losses more than doubled last year to about $1.9 billion, even as its total revenue also doubled to about $1.8 billion. But instead of expressing concern about the mounting losses, executives argued that they were a sign of the company’s giant ambitions.

“We can very much, if we chose to, moderate our growth and become profitable,” Artie Minson, WeWork’s president, said in a telephone interview. “But it’s a time for us to continue to accelerate.”

Michael Gross, the company’s vice chairman, added, “We’re looking at building this business out, not just maximizing profitability over the next one to two years.”
