When doing a startup sometimes is optimal to have someone at your side as the technical brain so he or she can develop any product you want to build. But beware of the concept now that it can be tricky sometimes to decide what do you look for because it exist a enormous difference whether you need a developer or a cofounder.

You may think you need both, but here some huge differences:

A developer is a guy who most of the time when coming on early stages you will pay on cash or equity. Maybe a combination of both so he can build the product from the scratch. it is like a contract, he will not be a part of the decision making on the product, he will only develop whatever features you want in the order you think is necessary.

A cofounder is most to the time is a long time friend or someone kind of close to you. Which you can trust and his product decisions will have a huge impact. He or she will take care of things but it is necessary to have consensus on everything. if you want someone just to develop your dream app and don’t want anyone to tell you what to do you should hire a developer.

There are many other reasons whether you need a developer or a cofounder.
choose wise.
