I'm currently working on a SaaS like this:
https://www.rationalbi.com/It's meant to be a modern take on BI/Analytics, and sort of a blend between dashboards, scheduled reporting and notebook analytics (like Observable/Jupyter).
You can just drop in data files of any kind, syndicate data from your cloud drives, connect to remote databases, upload via the API, and it has 80k+ open datasets available for analysis and benchmarking.
It also has a full SQL database running in the browser, so if you build dynamic notebooks/dashboards with business logic, you can do really fast SQL without any network latencies.
