01

Mark — The Pictogram

The pictogram is the exclamation mark of Eureka! — this is the generative concept behind the entire identity. The vertical stele is the body of the «!»; the azure halo is its dot. A standalone glyph with Fibonacci/φ proportions, the halo is the only animated element. Works as institutional stamp, favicon, avatar, centrepiece. Two variants: HALO (with concentric rings) and FLAT (mark only, without halo).

One glyph. One idea. One brand.

Wordmark — EurekaGO

A custom wordmark built from two weights of Archivo: Black (900) for Eureka, SemiBold (600) for GO. The mark is used purely as a construction reference — rotated −90° and aligned to the top-right of the text — to derive the oblique cut axis. A single diagonal cut along that axis produces the final, self-contained wordmark. The mark does not appear in the finished lockup.

H Vertical System — Brand Endorser How EurekaGO appears on vertical products

EurekaGO uses a visible endorser model, similar to "A Google Company." The Tiny wordmark appears on verticals as a quality signature — conveying the value of the integrated data and expertise system, without overshadowing the vertical brand.

Placement

Footer of the vertical, or header as secondary co-branding. Never larger than the vertical brand.
