About Workbench
We renew websites without breaking the brand
Workbench is the AI Website Renewal OS — brand-safe, analytics-driven, and PR-reviewed. We help teams improve every property with evidence-based AI proposals that stay inside design systems and approval flows.

Why Workbench exists
Website change should be measurable and reversible
Most site updates still start with opinions — a redesign brief, a campaign deadline, a gut feel about the hero. Meanwhile bounce rates and conversion gaps sit in dashboards nobody connects to the actual UI.
Workbench closes that loop. Connect analytics, surface the weak spots, and get AI pull requests for layout, style, and SEO that cite the WHY (data) and the WHAT (change). Designers, marketers, and compliance review the same artifact.
We are building for teams that manage many properties and cannot afford brand drift — or another CMS that ships unreviewed AI output.
The founder
“AI should propose website changes the way a senior designer would: with evidence, inside the system, and ready for review — not as a black-box rewrite.”
Workbench brings together product, design, and growth operators who have watched brands lose months to redesigns that never move KPIs.
Our bet is simple: renewal works when every change is measurable, reversible, and governed — across the whole portfolio.
