Pinterest, a social media site designed for "pinning" clothes, inspirations, crafts and other do-it-yourself attractions, is undergoing a corporate push as the company prepares to go public, after it confidentially filed an IPO with the SEC last month.

As of September the site boasts about 250 million monthly users, adding to the technical demands.

Data that's most important to Pinterest comes from images, shared web page information, which can include user comments, and graph data highlighting interests of an individual user as it continues to push for more mobile shopping. In September, the website opened its content marketing API to third-party influencer marketing platforms to make collaboration between marketers and influencers easier.

In comparison to its active users, Pinterest's engineering force is dwarfed, which means every additional function they add to the platform must be wholeheartedly understood. Artificial intelligence for the sake of AI isn't Pinterest's goal. Instead, it's understanding the relationship between installed features and their potential outcomes.
