Congrats on the startup success and (more importantly) I hope your daughter is well. There's a really valuable lesson here for would-be YC founders: > We had high hopes about getting into YC for the winter batch, but were rejected since we only had a non-functional demo of a product and zero traction. ... > This amazing traction helped us get into YC several months later... Same founders - traction = YC rejected Same…
I'm pretty sure they've said multiple times that traction is the best indicator of future success. Very rarely do they fund startups without traction (if they do, it's usually someone from within their network).
