Background

As generative AI adoption surged, prompt engineering emerged as a valuable but poorly monetized skillset. High-quality prompts were scattered across forums, spreadsheets, and private communities, with no trusted infrastructure to support creators or buyers.

The ecosystem lacked a way to:

• Sell prompts securely
• Establish creator credibility
• Support payouts, reviews, and lifecycle management

The opportunity was clear: build a focused, production-ready marketplace designed specifically for prompt creators and serious buyers — not a generic file marketplace.

The Challenge

Business Challenges

• Prompt engineers lacked a reliable monetization channel
• Buyers struggled to assess quality, credibility, and outcomes
• Existing platforms were either too generic or lacked trust mechanisms

Technical & Operational Challenges

• Designing a two-sided marketplace with clean role separation
• Preventing prompt scraping and content abuse
• Handling secure payments and payouts at scale
• Supporting prompt versioning with lifetime buyer access
• Building admin tooling for moderation and governance
