You said the icon is the brand — so each of these is built to stand completely alone, at any size, with no name needed. New territory this time: no triangles, no diamonds, no app-tiles. Same color theme you love. Point me at the one (or the family) that feels right.
Each mark is shown large and animated, with a one-line concept. Don't overthink the meaning — react to which one you'd be proud to put on a card, a website tab, and a sign.
The icon has to survive next to the name and shrink to a browser tab. Here are the two I keep coming back to — "Insight" and "Monogram" — shown as full lockups.
Where I land: if you want the icon to mean something about the work, Insight (01) — it ties to the audit, it reads as an eye, and it's ownable. If you want pure, can't-be-copied identity, Monogram (06) — it's literally you. Tell me which one to develop, or which two to merge, and I'll build the full set: every size, mono versions, favicon, and drop it into the hero and the brand guide.
