Eight candidate marks.
Pick one.

The shipping mark. The outer loop opens at 12 o'clock and a satellite node sits inside the break: work entering the system. An opposed inner arc gives it rotation; the solid core is Optimus. Three true readings in one geometry: a gate (the agent fleet admitting work), a speaker driver seen front-on (the industry's own object), an orbit (an operating loop that never stops). Compact variant drops the inner arc below 16px so the favicon stays crisp.

The v1 mark, retired 2026-08. A perfect O with a 4° notch at 12 o'clock and a solid disc at center. Clean, but the notch vanished below 48px and the silhouette read as a generic circle-and-dot. The Gate keeps its DNA (container + core) and makes the signature legible at every size.

Three rings at decreasing opacity wrap a central point. Reads as emanation, broadcast, orbits — the brand 'radiates intelligence outward'. More poetic than minimal. Slightly busier at 16px favicon.

Five rounded vertical bars in classic spectrum-analyzer rhythm. The most literally AV-coded option — your audience reads it as 'audio/signal' immediately. Risk: too genre-specific, less timeless than the geometric O family.

A solid core node connected to four cardinal satellites with hairline lines. Reads as 'one platform connecting many endpoints' — exactly Optimus's positioning. Slightly literal but on-message.

The Greek letter Omega rendered as a custom letterform. 'Optimus' is Latin from Greek roots meaning best/highest; Ω evokes that lineage. Distinctive against the SaaS-O sea. Risk: reads more 'mathematical' than 'AI'.

A six-sided container holding the AI core. Hex shapes carry strong 'tech/network/blockchain' associations — gives the brand a more engineering-grade signal. Distinct from the circle-O family.

A ring with one offset solid node in the upper-right + a smaller centered core. Reads as motion, activity, an agent orbiting the system. Pairs beautifully with a CSS rotation animation (the dot can literally orbit on first paint).

Drop the tile entirely. 'Optimus AI' in Geist Sans with tight tracking, gradient under-accent on the wordmark. The Stripe / Linear-wordmark approach. Frees us from competing in the 'letter-in-a-box' SaaS pile but loses favicon recognizability.
