If you can't make the economics of paid acquisition work, consider using self-liquidating funnels to break even on ad costs and acquire email addresses for future marketing efforts.

"The idea here is, if you push that, and if enough people buy this cheap, say $50 $20 thing, that it at least breaks even on your ad cost... And then you use emails like drip sequences over the next few months to convert that person to buy the primary product."

Product led growth is a healthy and viral way to grow, focusing on the quality of the product experience and encouraging users to invite others or share their usage.

"It's like the healthiest thing that no one can take away from you that you can optimize over time and tends to be the most viral."

Giving away money or other incentives can be a powerful way to attract customers, especially if presented in an appealing manner.

"When I can present something to someone in the framing of we're giving away tons of money... the ads tend to perform extraordinarily well."
