Circular Fashion × AI Agent Development

We build it,
and we run it.

The way discarded clothes get a second life, and the apps you'll find in the store — we started both ourselves, and we still operate them.

Creating a world where every fashion lover can enjoy fashion even more

MODALAVA designs new circular systems for fashion, starting with the simple choice of "not throwing away." Through technology and creativity, we build a world where clothes are reborn and passed from person to person.

About MODALAVA

Why one company does
both fashion and apps

Since 2017 we have launched flea market events, e-commerce, a physical store and a remake community to change the structure that sends clothes to landfill. None of them stayed on paper — we have run every one of them ourselves.

Along the way we kept needing tools of our own: managing inventory, matching people with clothes, keeping a community moving. Building those tools is what led us into app development and AI agent development.

That is why, even on contract work, we never "build it, hand it over and walk away." Our own apps are live in the stores, and we operate and fix them every day.

Our Story

Clothes still worth wearing
are being thrown away

Over 13 billion garments are discarded in Japan each year. Clothes with so much life left simply disappear without reaching anyone — we set out to change this structure at its roots.

By redesigning the flow of fashion through technology and creativity, we transform "discard" into "circulate" — building a society where clothes are passed on across people and generations.
