Why is there no company for some apps?

Curating companies to apps is actually a quite challenging task. For example, there are cases where the app developers report false information: https://mixrank.com/playstore/apps/com.hsj.bcae18. Notice here how the developer listed petsmart.com as his website.

This user-generated content issue is one we are working on fixing by supplementing many of our various, other data sets. There are also instances where developers list their website as a YouTube / Facebook site, which we need to delve into and figure out the correct company entity.

Furthermore, anyone can make an app and publish it to the store; thus, if we don’t have a company entity, there are countless instances where this is simply because there isn’t a company tied to the app.
