Cedric is a college student who built PepAI and hit $50K in revenue in 7 weeks. $11K MRR, ~2,000 active subs, $10/mo or $45/yr with a 3-day trial.

The stack is dead simple:

Repl.it + Claude to vibe code the whole thing in ~2 weeks
Firebase for backend + user data
RevenueCat for in-app subscriptions
Resend for email
PubMed sources powering the research library
Apple Health for the lifestyle + tracking layer

The real edge wasn’t the tech. It was spotting peptides trending on TikTok before anyone shipped a serious app for it, then moving fast.
