URX was YC S13. From their launch thread (<a href="https://news.ycombinator.com/item?id=6514604" rel="nofollow">https://news.ycombinator.com/item?id=6514604</a>):<p>> Our target customers are mobile commerce companies like LivingSocial whose inventory 1) has a higher cost of sale, and 2) isn't subject to the 30% App Store rake. This means that they are willing to be more aggressive with their paid marketing, similar to how things work on the web.<p>If the target demographic was <i>LivingSocial</i>, this was kinda inevitable.
If any company has a chance to make deep linking/in-app search work, it's Google, maybe Apple. They already have the mobile ecosystem and control it. The recent troubles of URX, Quixey etc. illustrate the uphill battles startups will face in this space.
