My experience in for parts: Motivation, Partners, Planning and Starting:

I wished to find a partner who really increased the value both professionally and on a personal level. I wanted him or her to be just as eager to found a company as I was myself. Another requirement was that we had to harmonize both as two human beings and with respect to our age, not to forget common shared values.

At one time, I thought I had scored. Together with a colleague of mine, I had already started actual planning. But then he had to pass for financial reasons. Again, I was by myself.
In the end, I got lucky. A cherished soccer friend (unfortunately he is now dead) and fellow employee was in the same situation as I: he wanted to become self-employed. Our knowledge and abilities seemed to complement each other.

And my soccer friend also brought a friend, so now there were four of us.
Together, we wanted to establish a new company specializing on electric data processing. The way there proved to be long and hard. Today, I believe that finding the right partner is the most important requirement, as well as the greatest challenge for establishing a company.
