Followers can lie. Comments can't.
@jakecastilloooo (co-founder and COO, Cal AI) on how to tell whether a creator niche will convert before you spend a dollar: read the comment sections under its biggest creators. Are people asking for a solution your app solves?
"If so, that's prime time. You know, you go full steam ahead."

Hard paywall apps convert 5x better than freemium. That number is real.
It also only measures one of the three things people mean by "hard paywall."
In our latest <15 min tl;dr video @drbarnard sorts out the other two, with BoldVoice, Opal, Natal, Ladder, and Phil Carter.

1/ BoldVoice is at $10M ARR with a team of 10.
One early decision: charging from the first weeks of YC. $10 a month, one-week trial, nothing fancy.
@AnadaLakra on why charging early was how they found their customer 🧵

I’ve sold three apps, and never shared the sales price or numbers behind them. Founders rarely do!
But this Thursday an app founder is letting me and @alwaysjoshp (who buys apps for a living) dig into his numbers live and come up with a valuation.

This Thursday: a founder opens his real books, LIVE on air.
@alwaysjoshp buys apps for a living. He's going to value one in public, with the founder sitting right there.
We're not saying whose app it is until we go live.

First app shipped. Apple hadn't paid yet. Dad said no to the bridge loan. So @drbarnard sold the Honda Accord. 🚗
