A great first step would be offering geographical location of an entity, at least at a country level which is enough to paint a broad vision of available companies in X country. Being able to filter the list by country would be great.
This would allow local communities to redirect to the country-level list while having introduced the subject in their local language - as an example I wouldn’t ask the EEF to maintain French copy, but could refer them to a pre-filtered list on the EEF site, either in slides, an e-mail, or a web page.
If there is interest expressed towards an actual geographical map, it gets a bit more complex as some companies will have multiple locations and a (City, Country) level of precision is a better UX. But I wasn’t thinking about a map, because it creates more vetting and verification work.
Language would be a nice touch but is a separate dimension. The ability to select one or more languages as a company profile creator would be nice. Then someone could link to german-speaking Elixir companies, but not care as much about the geographical aspect.
Note that those are only suggestions
