> How can you control the market?
I think the phrase "control the market" in it's classical definition: a monopoly. It means control the definition of the market. By "controlling the market" your set constraints that should make it easier to get the product right, and then easier to sell after launch.
> The market seems like a timing and luck factor that's outside of your control.
There's a lot that is outside of control in any startup, or for that matter, when you bring a new product to market in an established company. Some of it is luck. Some of it is being able to quickly iterate and improve. Some of it is having the capital to stay on the playing field long enough. The timing part is the hardest, and is so complex that it might as well be luck. In the end, you control what you can, and have to be ok with riding the trade-winds and current on the rest of it.
