Netsertive has acquired digital marketing firm Mixpo. The robust growth in online advertising has supported strong merger and acquisition activity for digital ad agencies.

Seattle-based Mixpo produces video ads that are shown across websites, mobile devices and social media. The target has previously done work for A&W, Arm & Hammer and Discover Financial Services (NYSE: DFS).

“With the combined capabilities of Netsertive and Mixpo, our clients can scale their digital marketing across local retailer networks of any size to reach digital shoppers, influence their choice of products, and ultimately drive buyers to local businesses," says Netsertive CEO Brendan Morrissey. Financial terms of the deal were not disclosed. Morrisville, North Carolina-based Netsertive provides local digital marketing services for companies across the automotive, healthcare, consumer and technology sectors. Netsertive has venture capital backing from RRE ventures, Greycroft Partners, River Cities Capital Funds and Harbert Venture Partners.

As consumers continue to buy more online, marketing firms that have the resources to appeal to shoppers on the web have become attractive targets. In 2017, Advantage Solutions purchased rival agency Brand Connections; Bain Capital Private Equity acquired a majority stake in firm Daymon Worldwide; In 2016, Trans World Entertainment Corp. (Nasdaq: TWMC) bought Etailz; and Xaxis, the operating company of communications and digital marketing firm WPP plc, bought Triad Retail Media.
