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.
If you want a one-man-show you need to do both, reasonably well until you can hire someone to do the other.
LevelsIO on Twitter is a good role model there.
