Our Team
Who we are
We’re a tight, passionate team of collectors and builders on a mission to bring AI pre-grading to everyone, fast, accurate and accessible from your phone.
Our Values
What Drives Us at Gradeon
From building powerful tech to staying connected with our community, these values keep us focused:
Collector-First Design
We design tools that we’d want to use ourselves — clean, fast, and built around real needs.
Transparency & Trust
We show you what the AI sees — and how it thinks — so you're never in the dark about your card’s condition.
Accuracy Over Hype
We test our AI like pros test cards: critically and precisely. We aim for reliability, not just buzzwords.
