There's already IBM's DataStage. I currently use this for ETL work at my job, although we're working on moving our ETL work to Python and an in-house framework due to licensing costs.
I know there are various Extract Transform Load tools aimed at professional data scientists. My product is aimed at numerate professionals who aren't programmers or data scientists and have never heard of 'ETL'. The idea is that they can install Easy Data Transform, transform their data and output it in a few clicks, without programming. It is also very cheap compared to many commercial ETL tools.
