Most founders have an idea, decide it's something they would like to pursue, then spend many weeks/months working to validate it, build MVP, attract customers. You can't deny that WP Curve started and gained initial traction exceptionally faster than most.
I disagree. Most founders with an audience can generally get 10 paying customers fairly quickly. And, frankly, I think 10 days isn't at all fast, especially these days.
And the impressive part of this story is its not 10 customers within 1 week of "launch" day. It's 10 customers within about a week of deciding on the "idea". Idea --> MVP launch --> Paying customers... 1 week.
