For those recommending the Kawasaki book, has anyone actually read it, and if yes how practical is it in your opinion. I have taken look through and it seems more like a motivational book than a hands on guide/handbook to me. I may be wrong, but I doubt it has the resources the OP needs e.g. it tells you to write a business model but doesnt say what makes a good one (advised to ask a woman -wtf) .
On success/failure of tech startup, I believe most fail because they are too focused on the technology/product side, and fail on the business side of things. One needs to always remember that it is a business and not a science project.
For the OP: In the beginning, I would expect one to work on having answers to some questions like (not mutually exclusive)
1. What is the problem and what is your intended solution
2. Who are the customers, what is their need that you are trying to meet, and how much are they willing to pay for it
2. Where is the opportunity i.e. market size, growth potential
3. What are the financial characteristics: investment cost, revenue, margins, profit, ramp cost and rate
4. What are your key costs e.g. product developments, customer acquisition, operational etc
5. What is your business model and strategy logic i.e how is what your doing going to make what your are doing better (e.g. more profitable?).
5. What are the technical, business, market, and/or legal risks?
6. Who are your present and future competitors, both direct and indirect, and what are the barriers to entry for others
7. What is your differential advantage that lets you do better than others e.g. better product, patents, or lower price
