It is better to work with an outsourcing company in the MVP and early stages to build the product than finding a tech co-founder. There are several reasons:
1. it is very hard to find a reliable tech founder.
2. you will have to convince the person about your idea and also give away liquidity.
3. Even if you find, it doesn't mean that tech co-founder will be able to do everything, you still might have to hire some developers to do tech work.

I would suggest to go with outsourcing now. I have written a detailed blog here, you can check more details:
