Narrativ founder and CEO Shirley Chen said there’s a big revenue opportunity that’s gone largely untapped by online publishers — namely, the links those publishers are already using to direct readers to buy the products mentioned in an article.

Sure, affiliate links are a common business model, where publishers get a cut of the business that they’re sending to retailers. There are even companies like Skimlinks and VigLink that automate this process.

But Narrativ is doing something a bit different. It turns these links into an advertising unit called a SmartLink, where different retailers can bid in real-time for each click.

The company has raise $3 million in funding from investors including Talis Capital and New Enterprise Associates.

Chen previously worked at the intersection of commerce and media, serving as head of marketing at Moda Operandi, the e-commerce company backed by Condé Nast-owner Advance Publications and LVMH. She argued that SmartLinks are a more effective form of promotion than banner ads (which are intrusive and can be stripped out by ad blockers) and native advertising.

“Native advertising mimics real content,” Chen said. “Narrativ advertising is real content.”
