Well I did have a SaaS idea until I realized Airflow and its clones already exist. But I think I see a niche with a moat: Small teams/departments.
Airflow assumes you have enough ETL jobs that efficiently using all the machines necessary to run them is a problem and you need dedicated schedulers and a Kubernetes cluster- like $10m enterprise contract stuff.
No one wants to do anything for a team with just 1 ETL task that runs nightly.

on the other hand, a small department level project often doesn't have money to buy anything- they got a FTE for a software developer, but no money for an IDE, nor a developer laptop, your server is shared with other departments, so paying for Airflow-but-for-smol-teams- they're probably not paying for that either. But if they did, that still wouldn't be a niche that enterprise sales teams would**n't** pursue-- too small.
