WhatsApp & Instagram were I think both very small teams with very many users when Facebook bought them (I think was FB not Meta at the time) for very much money.
Which maybe goes some way to your second question, as they were slightly and slowly scaled up versions of solo serving 1M. (And obviously have continued that under FB/Meta with probably now a much less impressive/unusual staff:user ratio.)
