I Built A $30K/Month in 35 Days

Cedric noticed he trusted everything peptide creators said, so he reasoned their followers would download an app they promoted. Before launch he reached out to a few niche creators to make posts testing interest (all said yes). He aimed to reach them before any competitor and get them to present Pep AI as 'the tool I use'. One creator's single Instagram story drove ~$1K revenue; his first feed post got 50K views and ~$4K that day, and ~$10K+ total. Compensation terms were not stated.

Before launch, had a few niche creators post about the upcoming app and made Reddit posts to gauge interest, collecting sign-ups on a waitlist. About 300 people joined, which confirmed demand.

After a roommate mentioned peptides and a peptide TikTok hit his For You page a week later, Cedric saw peptides were huge on social media and that the few existing peptide apps (some a couple of years old) hadn't succeeded. His process: scroll TikTok/Instagram daily to spot what many creators are obsessed with, then check whether apps exist; a couple of unsuccessful apps is a good sign (demand proven, nobody has marketed it well). He chose a narrow audience after his broad first app failed to monetize.

Went through every review of every existing peptide app, noting what people like, dislike and wish the app had. Fed that into Claude (or ChatGPT) to come up with the app concept and had Claude run research searches so the content (peptide library, PubMed sources) was actually useful.

The app (named Pep AI) ranks in App Store search for peptide terms. When a copycat called Peptide AI blew up in a post on X, people searched 'Peptide AI' and Pep AI was the top result, picking up that traffic. Host found it #3 for 'peptide tracker' behind ads. No deliberate keyword work was described.

Apple repeatedly rejected the app for seeming to give medical advice. He studied how similar apps presented their features to find wording Apple accepted, and used Apple's expedited review request for major fixes, which returned reviews in ~2 hours instead of ~2 days. Approval took about a week overall.

For his first app, a University of Oregon student marketplace, he and his team went around campus telling people about it.

A founder Pat interviewed collected their app reviews, Stripe cancellation reasons and support requests, put them all into Claude, and rebranded the whole app based on the output.
