Hi guys. Just read this article and found it extremelly important. Very well writen article btw.
Find a co-founder is the first step in the journey or the second (if you already have an idea). So take it very carefully. It has a tremendous impact in your future such as investment hunting and the daily operations of your venture.
After this topic I'd recommend write down a founder's agreement which will make easier the work togheter (and secure for your investors as well).
I hope it helps you on the search for a co-founder! Good lucky!
