Startups

When hiring programmers for one startup, how can you be sure that they will not steal the very idea of ​​​​the project in its infancy?
Can someone share their experience?

Answer 1

And how will they implement it, without your support, primarily financial? That is what experience is, unsuccessful!

Answer 2

Well, I already answered .... only NDA and so that they already have their own project, nothing else!

Answer 3

Don't tell anyone about her

Answer 4

How to protect the project from theft by the programmer?

Answer 5

Divide into small pieces.
Entrust the development of these parts to different people.
Do not forget to sign an agreement on the alienation of copyright. In addition to a regular employment contract.
Without such an agreement, everything that the programmer has written can be legally used anywhere.
