I used to think "Learn to Code" was the best advice out there to find a technical co-founder. That's what I did and it worked great.
But honestly, if I went back I wouldn't have learned to code. I would have learned enough to put up a basic lead capture page using unbounce or leadpages or some other landing page out-the-box product and started marketing.
Most good businesses can get some traction without any code. And people are always willing to talk if you have a product that already has some traction - even if it's very minimal.
The key is to figure out some super scaled down version of your product and use it to get some initial traction.
