The point you've raised about different types of data being stuck in different services across teams is a real pain point, especially for startups as we tend to embrace brand new tools. Segment (https://segment.com https://segment.com) is one attempt to be the "customer data hub". It never quite did everything I wanted personally. If it works for you, then you can hook it up to something like Keen (https://keen.io https://keen.io) and get a dashboard with nice realtime charts very easily. My most common approach is to let the data sit in third party services, then pull it together via APIs for reporting.
