More useful data to add

[AmeerHajAli]

Thanks for contributing this, it is very helpful!
It would be great to add the founder names, their linkedins, and if possible somehow the email addresses.

The dates format is currently 1636637510, would be great to make it an actual date instead.

Overall this is very helpful, thanks!

Thanks for the suggestions and the kind words @AmeerHajAli. Founder names, LinkedIn etc. are difficult to do in the current scope, as the directory listing API just sends the company data and not founder data. I would deliberately want to keep emails out of the repository for privacy reasons.
The data format looks fixable. Could you give it a try and send in a PR?
