Let’s be clear the goal wasn’t to break new ground in fact it’s the opposite. To condense all the accumulated pieces of advice that we give in one place and provide links to dive deeper if needed.
I agree you are trying to do that with this post. But YC startup information sometimes markets itself as knowing what others don't know when it comes to growing a business, and say they know best since they've seen so many startups in their cohorts. It comes across as revolutionary ideas, even if those words aren't exactly used.
For instance, all your reference links are to yourselves. Are there no data points outside your own findings that could be useful ?
