Collaboration with other people is good way for your business as long as you do it properly.
If you are a newcomer in your industry, it is very helpful that your partner introduce you to his followers or customers.
Because no one knows you right after you start your business.
It is also helpful even if you have sufficient results to collaborate with other people.
To make a collaboration successful, the most important factor is who you collaborate with.
It doesn’t mean that you have to choose a successful entrepreneur as your partner always.
But you have to choose a person who have a common philosophy with you.
Otherwise the collaboration would fail.
Because the purpose of such a collaboration tends to be just money.
That is, you and your partner just want to earn money, but you guys don’t share a common philosophy.
I’ve heard many failure cases because of the reason.
The point is to choose like-minded people.
You should be careful about choosing people.
If you become successful to some extent, various people approach you about making collaboration.
Some of them would just want money. Such people are harmful to you.
