Alterist is a marketplace for Magic: The Gathering altered card art — a niche where artists hand-paint over existing cards and collectors buy unique pieces for hundreds of dollars. The community has been served only by generalist marketplaces (Etsy, eBay) that don't understand the medium.

Business Opportunity

Altered MTG cards sell for $200-$2000+. The community is passionate, vocal, and underserved by existing platforms. No purpose-built marketplace exists. AI/ML unlocks discovery features generalist platforms can't replicate — tagging by aesthetic, object, art quality, and eventually personal taste.


Personal Challenges

Build a multi-sided marketplace solo while running audience research, design, frontend, backend, ML integration, and go-to-market in parallel. Balance dev-first execution with design polish once concepts validate.


Goals

Build the purpose-built marketplace for MTG altered art. Demonstrate AI-augmented discovery as a category differentiator. Test what solo AI-augmented development can ship in product velocity. Expand into custom commissions, collections, and personalized feeds.


Tech Approach

  • TypeScript/React frontend
  • Claude Code as primary development partner
  • Gemini 2.5 Flash + 3 Flash for image tagging
  • Three ML models for aesthetics, object recognition, and art quality
  • Custom search and filter built on ML-generated tags


Coming Next

Taste profiles built from user behavior and search history. Continued marketplace iteration as transaction data accumulates. Commission flow refinement.
