Questions & Answers

Q: How did Cedric find a trending app idea for Pepai

Cedric found a trending opportunity after a roommate suggested peptides and a For You Page TikTok exposed the topic to him. He noticed there was no successful app explaining peptides or tracking safety, so he scanned existing apps and reviews to identify gaps. This gave him a chance to build a focused tool for a growing, underserved audience.

Q: What was Cedric’s background before Pepai

Cedric was a college student who built an earlier student marketplace app at the University of Oregon, which taught him the value of targeting a niche. He learned that revenue comes from solving a specific problem for a defined group, and used that insight to pursue a more scalable, revenue generating idea with Pepai.

Q: How long did it take to build Pepai

Building Pepai took about two weeks, aided by AI tools like Replit for rapid development and Claude as a guide. This allowed him to set up the backend with Firebase and handle revenue features and email automation without advanced coding, though some app store constraints still required iteration.

Q: How long did the Apple approval process take

The Apple approval process took about a week, with back and forth to satisfy review requirements. Cedric learned that expedited reviews could accelerate the process when there is a major update, reducing typical wait times to about two hours in certain cases.

The suggested method is to spend time on social media daily, watching what big content creators discuss and identify topics that are gaining widespread attention. If a topic shows sustained interest, it can be turned into a useful app, and rapid validation should follow with minimal viable product steps.

Q: What would Cedric do if starting over in mid 2026
