Ask HN: Here is your 50%, "non-technicals"

I am a software engineer and entrepreneur with around 7+ years of experience. In all my startups or corporate jobs I have worked in, I have always been in technical / software development positions. In the startups I have been involved in (I have 2), I can say that I generally find myself successful in the technical and business development stages, but in the "marketing" stage, which is very vital for a startup, I fail every time and it seems like a chore to me. One of the main things I do wrong is that I feel like potential customers or people in general are robots and I have to program them in a very deterministic way to buy my product. I know this approach is wrong, but every time I try, my attitude evolves here. Thank God that in every startup I've been involved in, I've had very talented co-founders to handle that part. They feel the same way about my technical development skills. That's great, but it's the interdependence and not being able to turn it into a "one-man show" that gets me every time. How can I go about this, can I get out of this mess? If the answer is really no, send me an email for 50% (egesabanci@outlook.com.tr), I have some new ideas. By the way, ignore the title, I phrased it that way to draw attention.
