Pinterest has taken a long time to justify its monstrous private market valuation. However the social media company is finally approaching $1 billion in ad revenue as it pushes toward an IPO in mid-2019, according to people familiar with the matter.

After hitting $500 million in sales in 2017, Pinterest is on pace to almost double this year, said the people, who asked not to be named because the company's financials are private. Pinterest is having particular success with mobile ads, as the site becomes a more popular place for big fashion and beauty brands to get in front of the company's 200 million monthly active users.
