In April, Pinterest announced its Marketing Developer Partners (MDP) program with the goal of helping businesses get more value of their Pinterest efforts.

“The program helps businesses optimize and scale their Pinterest marketing and improve Pinterest for Pinners,” a spokesperson for Pinterest told us. “The initial MPD program is made up of a limited, carefully selected group of developer partners who meet the needs of existing businesses on Pinterest and align with Pinterest’s core value of putting Pinners first.”

These partners include: Ahalogy, Buffer, Curalate, Expion, Newscred, Percolate, Shoutlet, Spredfast, Sprinklr and Tailwind.

At the time, Pinterest also said it was in the early days of testing its Ads API in the U.S. in an effort to help advertisers optimize their campaigns and find “sustained success” on Pinterest. The company is now talking more about this, and has revealed the first MDPs using the API. These include: 4C, Adaptly, Ampush, Brand Networks, HYFN, Kinetic Social, SocialCode and SocialFlow.

“We selected these partners because they’re building tools that address the immediate needs of Pinterest marketers and share in our vision of creating a better discovery experience for Pinners,” says Pinterest’s Jyri Kidwell. “We’re already hearing lots of positive things from businesses working with our MDPs.”

Jody Ford, VP of global growth at eBay, for example, said, “We want to make eBay relevant to consumers at the moment they’re inspired to shop, and Pinterest enables us to put the right content in front of the right people. By working with one of Pinterest’s Marketing Developer Partners, eBay can buy Promoted Pins to promote interesting trends and topics with Pinterest users, making them instantly shoppable. And we’re encouraged by early results, which have shown a significant increase in traffic from Pinterest to eBay.”

According to Pinterest, Adore Me, a lingerie brand, saw a whopping 4000% increase in Pinterest-referred revenue after working with 4C, using the Ads API. They have a case study on the brand available here.
