The problem
Crown Collectibles needed an intake site that did the work of an experienced buyer: prove credibility instantly to verified collectors, capture mixed Pokémon collections without friction, and feed every submission into an ops workflow without losing the human voice the desk is known for.
What we built
We built a Next.js 14 marketing and intake site anchored by a written brand voice charter. A multi-step quote flow uploads photos to Vercel Blob, persists to Neon Postgres, runs synchronous PSA / CGC / SGC cert lookups inside a 3.5s budget, and triggers an async gpt-4o-mini vision pass that classifies photos and emails a triage report to ops—never the seller. Resend handles transactional email, Slack pings the desk, and a signed status page lets sellers check progress without an account.
