Meal-delivery service Blue Apron has filed an S-1 to go public, and we're getting a detailed look at its financials for the first time.

The company has posted losses, and says in the filing that it anticipates it will continue to do so.

"We have a history of losses, and we may be unable to achieve or sustain profitability," the company says in its S1.

It's losses have grown year-over year too:

2014: Lost $30.8 million

2015: Lost $47 million

2016: Lost $54.9 million

Revenues have been growing year-over-year, however. Here's what the last few years looked like in revenue growth:

2014: $77 million

2015: $340 million

2016: $795 million

Here's an interesting look at the ages of Blue Apron customers. Most are 25 to 34 years old:

The company also spends a ton on marketing. (If you've ever listened to any major podcast, you've probably heard a Blue Apron ad.) The company spent $144.1 million, or 24.8% of its revenue, on marketing in 2016.

Blue Apron was founded in 2012 and has raised nearly $194 million in funding to date. It was last valued around $2 billion. The company is known for sending pre-packaged and pre-measured meal ingredients directly to customers, along with the recipes to make the meal.
