Acceleration Partners has acquired Streamline Marketing, a Seattle-based performance marketing agency founded in 2013 by CEO Jon Claydon.

All Streamline employees have joined Acceleration as of Jan. 1, resulting in a combined company with a 200-person team, as well as an expanded presence on the West Coast.

Acceleration Partners says that the acquisition will add Streamline Marketing’s strong data analytics and loyal customer base to its global affiliate marketing expertise and resources.

“We’ve had a strong relationship with Streamline for years and greatly admire what Jon and his team have built,” said Acceleration founder and CEO Robert Glazer, adding the company will now be able “to offer leading brands expanded senior-level strategy, increased global coverage, proprietary technology-enabled solutions, and the highest standard of affiliate and partner marketing program management.”

The Streamline acquisition is Acceleration’s first since partnering with Mountaingate Capital in December.
