| That's an unanswerable question the way you put it. There is absolutely no information even about size of the potential market, business model, competitive arena, price points, required capital investment and so on. You will have to do a bunch of homework (such as a minimalist business plan) to give you an idea of what you expect to do with your business, then you can go and put a value on it. Garbage in -> garbage out. YC has turned the angel investor game in to a horse race, they bet on the teams, to a much lesser extent on the ideas. 'conventional' angel investors will likely not be able to evaluate you (and possible co-founders) as a team, but they may be able to understand the business proposition behind your idea once you can explain it to them. That will be central to the valuation, as well as your expertise and skill relative to what is needed to develop it and take it to market. A couple of weeks of hard work should get you to the point where you will be able to answer your own question, after all, you're the one that's being diluted so you should know the value of what you have better than anybody. |
