The Largest Direct Supplier of Native Ads
STX is the first ad exchange built from the ground up for programmatic native advertising.

Native is the Standard for Modern Advertising
Advertisers are projected to spend $21B on native advertising by 2018* because, simply stated, it works. Native, in-feed ads are shown to receive 308x more visual focus and drive 18% higher purchase intent than banner ads, making them the ideal key tactic for brand advertising.**
