I think everyone will agree that a newborn idea costs nothing. However, there are at least two ways to benefit from the fact that for now nothing costs:
Sell. Together with the project documentation and calculations. Optimal with its services and interest.
To implement. Either through their own investments, or a team of like-minded people. Optimally at the expense of the investor with the office and staff.
In any case, before you undertake anything, you should spend a little time on the rejection. And not necessarily in a “proven” way - put off another for a day and reread again. Every good, really worthy idea will necessarily meet at least several of the following criteria (examples for clarity, not more):
Timely . Did you get washing machines with AI? New soc. the network where they would communicate with televisions is a good idea.
Unique. Service, content, feed. A low-paid job search site for the homeless is a good idea.
Affordable. The description and purpose of the service / project fits in one sentence and is understandable to everyone, including the translation. Good example .
Universal. Has the right to life not only in a given region. A good example is the international flower delivery service.
Innovative. No one has made this.
Only five to ten minutes of time and in the world, perhaps, there will be one less project than this one. More ideas, good and different.
