When listening to YC videos or general startup talk online I see the idea that you know you have Product Market Fit when you feel an overwhelming amount of growth that you can’t handle.<p>The Stripe founders said they knew they had it when a customer sent them brownies to get off the waitlist for a feature. Obviously, Stripe had built an amazing product that resonated with users but how much of that success was from a good product vs. good marketing/network effects?<p>I imagine there are many products out there that people have given up on even if it was able to reach PMF just because nobody knew about it.
