Great article, but I have a situational question: Let's say a company has grown at a 10% weekly growth rate and is now at 500 users. But as they try to sell to more people, they realize they are no longer growing at 10% and their growth rate is stagnant or decreasing WOW. Does it make sense to continue trying to sell OR focusing on user feedback and improving the product? I assume 'both' will be a popular answer but why? If you know your product is currently subpar, why not just build until the next iteration is ready and then start selling again?
Part of the sales process is taking the sales feedback and using it to improve the product continuously. If you're not doing that, you're missing the core point which is to improve the product.
Do you know why new users are not signing up? If you do then consider signing up new users on condition that you fill that gap. If you don't know why the growth rate has fallen then fill in that knowledge gap however you can (ie. talk to your prospects).
