How a 20-year-old built a $930K AI ebook business on Pinterest

Executive overview

Most people assume AI-generated content businesses require technical expertise or large capital. Joe Poplis built a $930K-valued ebook brand while in college, self-funded for under $500, working nights around a part-time job and full course load.

The model: use ChatGPT to generate structured ebooks chapter by chapter, sell them via Pinterest ads driving traffic to landing pages, and target emotionally motivated niches.

The core insight: the bottleneck isn't content creation — it's niche selection and ad-funnel execution.

Building the books

• ChatGPT generates the outline first; each chapter topic is then generated separately
• A full book costs roughly $3 to produce with GPT-3
• Proofreading can be done manually at the start; Joe later hired a retainer proofreader
• Study competitors' books before writing — congruency and structure matter more than polish
• First books were imperfect but still sold; iteration improves quality over time

Niche and audience selection

• Choose niches with high ambition: people who want a specific outcome
• Emotional targeting works best — present the outcome, position the book as the path
• Joe's primary audience: middle-aged moms and dads on Pinterest
• Pinterest is largely untapped compared to Google and Facebook ads

Marketing and ad funnel

• Start with consideration campaigns to identify which niches convert
• Move to conversion campaigns once a niche shows signal; dial in every stat
• Set up the Pinterest pixel (tag) before running conversion campaigns
• A landing page is non-negotiable — it's where value stacks, chapter previews, and brand image live
• Bounce rate above 70–80% signals a weak landing page, not a weak product
• Profit margin: 70–80%; the main cost is ad spend

Business model and scalability

• $390K profit to date; business valued at $930K
• Received a $930K offer on the first marketplace listing
• Sold 40% to an investor while retaining the brand to build a second one
• The model is repeatable: build a brand, sell a stake or the whole thing, repeat
• Competition entering the market hasn't eroded profits; the market is large enough
• Still only advertising on Pinterest — Google and Facebook represent untapped growth

Advice for getting started

• Prioritise learning over earning early on — skill accumulation reduces failure risk
• Start with under $500; mistakes are part of the first iteration
• Understand how generative AI models work and how to prompt them effectively
• Pick a niche before writing a single word
