As someone else said the company types you mentioned all are tech oriented and probably have devs who have internal processes already developed or in process of being developed if it's something they need.

Even if you tell your idea 99% of people won't do anything with it. If they do yours could still be implemented better and beat them or you could still beat them to market, or there could be a big enough market everyone can fit.

E.g there are like 10 uptime monitoring apps on indiehackers doing >3k mrr. Very simple function, tons of profitable competitors.

My advice is just say what it is you want to build and get actual feedback on the whole concept, you might even uncover better features by getting insight. Don't be afraid of people stealing your ideas. Ideas are a dime a dozen, successful startups are 1 attempt out of 99.
