The biggest advantage of systems like this isn't even the money. You can use the same data warehouse/SQL/BI tool stack to do sales reporting, analyze marketing spend, track support KPIs---everything in your business. My company (Fivetran) does the data-pipeline part of that, we event have a Mixpanel connector for people who want to operate both systems in parallel or migrate over time.
