> Personal (sic) a killer product to me is one that sells If you read the article, this isn't a B2C product. We were working with manufacturers and high-dollar contracts ($100m+ I think). A lot of different hands are involved, lots of due diligence, it had to match the manufacturers strategy, and laws and regulations are all questioned. Since a majority was mobile, we also had to involve the carriers. We also had to work with the labels and publishers when dealing with manufacturers in different regions. A lot of that work was over my head (since as I said, I just built the product... I'm also not sure how much I can talk about publicly, so I'm trying to keep it sort of vague). We had to work a deal out with everyone so they all get paid what is fair to them (we want to negotiate the lowest price, each one of them wants to negotiate the highest price), and those kinds of things take time. All of this happens over a period of months, while other parts of their (everyone mentioned above) business may be moving in other directions -- acquisitions happening, strategy changes, budget projections, layoffs, massive hiring -- you name it. In Y-Combinator land it is really that simple, but when dealing with big business, it's not. EDIT: Just realized I didn't answer the question. A killer product, to me, is one that I would routinely use, and that my wife uses as well. She liked to use the app (I can't say that for everything I've built). I did too. We also proved it would scale, and yada yada. I'm afraid of saying more, but yes it was a solid product.
