With the rampant rise in start-ups over the last few years, almost everyone who is sick of his/her job is ready to take the risk of converting an idea into a business. When he/she sits down to list out the things required to get started, it soon dawns upon the entrepreneur-to-be that one person alone can't do so much.
Do you need someone who can take all the product management decisions? If so then hunt for a Product Manager.
And so we start observing posts on Facebook - 'Co-founder' wanted.
The problem is this - Very (very) rarely are you going to find a co-founder this way.
Why?
Simply because a co-founder is not a standard designation of any professional. Yes, we all understand you are looking out for the partner. Not only are you showing how desperate you are, and weakening any scope of negotiation when it comes to ownership, you are also stating that you haven't researched your requirement enough.
While observing this sudden demand for co-founder, I commented to an acquaintance -' What you're basically saying is that I am willing to give ownership to someone whom I don't know, have absolutely no idea about previous experience, and that he/she will be thinking of the idea as passionately as I will'
This approach is usually a recipe for disaster.
What should you do then?
Do you need someone who can take all the product management decisions? If so then hunt for a Product Manager.
Are you weak in finance and need someone good with drawing up business charts and budgeting? Look for a Finance Manager.
My point is - try to identify the most important reason why you are hiring a co-founder and put that requirement out as the designation you are looking for. Once you have hired this person, and are happy with his/her skills in the domain, test the waters to see if he/she has an inclination towards the business. And that is when you're a better judge to decide if this person is worth being a co-founder
