If a startup can't attract talent (a sign of bad traction), that startup probably is not that good and more people won't solve the underlying problem. You would also be surprised how many startups outsource dev/marketing/etc. in their initial stages.
If you can't convince smart people to work for you and that your idea is good, good luck trying to convince customers of the same.
>And that 95% of startups don't know their metrics. Pretty sure almost all do but again don't have the skills or resources to meaningfully move them.
I said most don't know them as well as Mr. Beast. Read "Chapter 1: What makes a Youtube video viral?". Most founders have not put the same amount of time into seeing how to track, measure, and impact metrics. He identified key KPIs and then experimented with changes until he found what worked. His whole north star to, minute by minute, structure each video, is informed by the KPIs. His whole strategy is built upon metrics by metrics.
He clearly is obsessed with them to a degree few are. Some startups don't even know how much money they make, how much money they lose, etc.
