Design studio · Portland, Oregon
Brand systems, websites and products, built to pass review.
Portmanto is led by Amantu, who led the design system behind 8,000+ Prudential pages. One senior designer leads every engagement. No account managers, no handoffs.
What we have done
Prudential · Evolution design system
A design system 200+ designers and developers used
100+ Web Components for any framework, with a review gate on every one. Replaced an earlier Bootstrap and jQuery system that few teams used.
Wyndham Destinations · rci.com
A print brand book turned into a web system
Accessible web foundations, themed across 6 brands from one set of components. Web and email redesign for the world's largest vacation exchange network.
Avanoo · founding designer
A culture platform, from first designer to 11x engagement
One redesign, a goals and checkpoint system, a brand, and the Series A pitch deck. Built the design practice from zero.
Why we are different
Amantu leads every engagement. No account managers, no handoffs between agencies. The person who scopes the work is the person who does the work.
We build systems your team can keep running after launch. Tokens, components, templates. The work scales because it was designed to scale.
Accessibility is built in, not added on. Every component passes contrast, keyboard and screen-reader review before it ships. ADA Title II readiness for public agencies.
Live pages, not mockups. We show you what works in a real browser, on a real phone, before we ask for approval.
