We are a small data consultancy, so we use other/more diverse things for customers, but our internal stack is fairly simple:

Hubspot/Jira/G Suite → (Python) → PostgreSQL → (SQL) → Tableau

Since we are Tableau partners, we have a bunch of internal licences either way. We host Tableau Server, ETL, and PostgreSQL ourselves, all on Centos cloud servers.
