Hi! Quick story about coffee and indie builders.
You spent more than $15 on coffee this week. You'll spend more next week. And the week after that.
A Featured Brew costs $15. Once. No subscription. No renewal. Your tool pinned to the top of the feed for 7 days โ in front of every founder browsing for their next stack.
The coffee is gone by noon. The listing stays for years.
The coffee is gone by noon. This isn't.
