dynamically create subdomain

Yes, it's possible. Have you tried anything or read this https://laravel.com/docs/5.8/routing#route-group-sub-domain-routing

Sounds like a Multi tenant approach might help you. This will also enable you to isolate all tenant/company data in seperate databases or tables.

Take a look at https://laravel-tenancy.com/ or https://github.com/orchestral/tenanti for composer packages doing the heavy lifting.

If you like to do it yourself take a look at these two great blog posts:

@mthomas @fraserk : How it can be done dynamically? On successfully signup, you will be redirected to your own sub-domain. is it possible with above approaches?

I guess, the best way to find out is to give it a try.

But as you need to record the subdomain somewhere there is no reason you could not redirect there (its nothing more than a regular redirect).
