About Signatrue

Built to help collectors make better decisions about signed memorabilia

Signatrue combines digital analysis, reference data and a structured authentication process to help collectors assess autographs before they buy, sell or pursue further authentication.

Collecting should be exciting — not a guessing game.

Signed memorabilia can carry significant financial and personal value, but assessing authenticity can be difficult, expensive or inconvenient.

Signatrue was created to make the first stage of autograph assessment faster, more accessible and easier to understand.
