What they did
Thousands of messages to creators, kept up every day (on the order of 100 a day) for 18 months. Most didn't reply; many who did asked for rates too high to afford, and every negotiation was hard. Jake's view: being willing to do this grind is the edge, and it is harder now because creator rates have risen with more brands competing.
What happened
Hit rate was low, but sustained volume signed hundreds of creators.

In their words
Sub Club by RevenueCat · How Cal AI turned creators into a growth machine — Jake Castillo, Cal AI“So it's like, yeah, you are sending thousands and thousands of messages to creators all the time, and most of them aren't responding.”
“Because if people can do it for a day, they reach out to 100 peers like, oh man, that sucked. I'm not doing that again. We did that for 18 months every single day.”
