I am a technical cofounder myself. Still i believe a successfull business is the sum of many parts, not only the technical side. There are also enough stubborn devs that praise everything they build but still fail to bring it to a relevant audience. I agree with parts of this post, but overall i dont like this kind of elitist talk on here all the time on how everything else than technical guys is worthless. There a bad business guys and bad technical guys as well.
