Articles that indicate the costs (both time and money) for a startup

Question

Electronic commerce

Perhaps you have an article fresh in your memory in which the author shares his experience in creating a startup, indicating the specifics (that is, the money spent, time, etc. resources). If yes, please share the link.

An example of such an article: habrahabr.ru/blogs/startup/132832/

It is imperative that you can "feel" the service itself (its capabilities) and at the same time know how much resources were spent.

Let me explain the usefulness. Sometimes there are customers who do not realize the amount of work (here, just like the author from the article at the beginning of his journey). And such information, perhaps, would help bring back to reality.
