This is a great idea. I'd like to make a few suggestions though:

- Allow filtering by companies and libraries. I'm interested in both, but I wanted to look at just the list of companies to see if there were any I didn't recognise.

- Adding a company seems to be just adding _your_ app. It would be good to suggest companies to be listed as long as you have some evidence that they use Elixir. I know that Apple has Elixir in their Environmental team, but I'm not sure how I would go about adding that.

- Move the category filtering to the directory page. It would be more interesting to see the whole list at once and filter by category.
