Since 100% of the business relies on having the product and I don't have the skills to create the product, should I drop the idea or find a tech cofounder?
Because then I'm 100% reliant on the tech cofounder to build it and how do I know the person doesn't just build it and market it themselves?
You ca do this for certain and agree with the other answer that you do not have to have the skills to create the product. If you are going to bring on a co-founder for the tech side, legal agreements can be to ensure both of you are protected.
You can also think about outsourcing the technical work to one of many companies who can architect and build out your product, meaning that you maintain ownership.
There is surely more than one way to approach, but do not give up on your concept due to a lack of technical skills.
Happy to discuss more if I can be of help to you.
