About SOSEI

We've spent years fixing the exact problems this product solves. SOSEI encodes a 12-person agency into a subscription that stays current forever.

How it's engineered

Not another AI website builder

SOSEI takes your existing URL and rebuilds it — preserving brand, content, and tracking — through a 5-stage AI pipeline that grounds every decision in a curated catalog, then compiles the output through a renderer that the LLM can't bypass.

AI-native pipeline

Built on a purpose-built, frontier-AI pipeline — not a WordPress theme wrapper

161 industries

Catalog-grounded design and copy — not generic AI website-builder output

Source-language native

Estonian source → Estonian site. No machine-translated awkwardness

Renderer-enforced quality

WCAG contrast, motion, layout contracts can't be violated mid-edit

“Most outdated sites carry the same five problems — no schema, no llms.txt, no consent gating, fonts hotlinked from Google, images hotlinked from the old CMS. SOSEI encodes all of them as renderer-enforced defaults, so a regen can't ship without them.”
