Do you really need a co-founder if you feel very strongly about your idea and the business you're trying to build? You have to sell your idea. You have to know what problem you're solving, and for whom. Ultimately the buck stops with you since it is your idea and you finding a co-founder is only part of the execution. You can most definitely get by without one, as long as you are executing to your maximum capability. Don't feel like you have to give up valuable equity to someone who isn't a good fit, or someone who doesn't share the same passion as you about the BUSINESS. That's what is important. Are they going to be there with you 2/3/5+ years? Anyone can code or be a product manager or throw some designs together. Can they actually contribute to the entire business though? Are they going to help you sell? Will they help you putting out fires on another domain area? If all you need is someone who can code or some other piece of work, you can just hire a contractor to build your system. You can hire them as an employee later, if all they are is excellent in one area of operations. Maybe I'm wrong here, but in 2023 with all the tools and technology and access to experts, I don't think you need to worry or get so hung up about not having a co-founder. It is more than just a checkbox because XYZ said I need to have a co-founder. A good co-founder is always rare to find, rather be the best founder for the problem you're trying to solve and things will fall into place naturally.
