I worked a few years for German air traffic control and I own a PPL.
From a non-commercial viewpoint, I like to see when people get enthusiastic to make airspace and flying safer.
From a commercial perspective, I agree with others writing here that going into a highly regulated market such as air traffic, is very hard, and I can tell you why I think so.
For example German air traffic control (DFS) publishes tools which are not directly ment for ATCOS https://stanlytrack3.dfs.de/st3/STANLY_Track3.html , so they are already covering part of this market.
Then there are companies already specialised in tapping into the open data of the skies https://www.skysquitter.com/en/home-2/
(Or check https://droniq.de which is specialised in integrating drones into airspace). They are all either governmental or subsidiaries, or not directly involved in air traffic control itself.
I once built a 3D airspace app which I thought could become a commercial product, but I found it is too hard to compete with companies like DFS or Boeing (ForeFlight) and others. (I published the app for free to play around with: https://raphting.dev/confident/)
Saying that, I think I thought a lot about commercialisation of airspace products and my conclusion is that most countries have a good reason to leave air traffic control governmentally owned and continue gatekeeping for new entries. These gates are very well protected, and if it is only with high fees you need to pay to even gain access to data (like when I purchased airspace data from Eurocontrol for the 3D App).
Focusing on training or "post-ops", what I think you plan to do, is probably the more viable direction.
