Validoe

Validoe is an app that authenticates and pre-grades Pokemon cards, and reviews graded slabs and sealed product, by combining a global team of card specialists with AI assistance. You photograph the item, submit it for verification, and receive a report covering authenticity, grade potential and any signs of tampering - often within minutes.

Expert-backed authenticity verification

Submit a card, slab, booster pack or sealed box for review by a global team of authenticators, supported by AI. You get an Authentic or Replica verdict with the evidence behind it, rather than a score alone.

Pre-grading for raw cards and packs

For raw cards and unopened packs, Validoe assesses condition and grade potential before you commit to an official grading submission, helping you judge whether a card is worth the time and cost.

Re-grading for slabs

Already-slabbed cards can be re-assessed to flag possible mislabeling and to surface grade or value potential you may have missed - useful when evaluating a slab on the secondary market.

Reports in as little as 10 minutes

Capture card images in the app, submit for review, and choose a turnaround. Reports can be returned in as little as ten minutes, with watermarked images and written commentary from the authenticator.
