Collection score, artist score and activity level, all clearly visualised at a glance.
Collection value, score history, privacy mode — all in one view.

KF — the Kunstfaktor — is the German metric for value calculation. We compute it from real sales, not estimates or auction fantasies. Per format pool, per artist activity level.
