Webinar Overview

In an era when the culture of "renting clothes" did not exist,

airCloset challenged an unrecognized market and created a new option: monthly fashion rental.

How did they identify opportunities in a non-existent market? How did they define and refine customer value? And how did they nurture a precedent-setting business within their organization?

In this webinar, we invite Satoshi Amanuma, founder of AirCloset Inc., to deeply examine the decisions made from founding to IPO, under the theme "How We Discovered, Endured, and Cultivated a Market."

We will deliver the entrepreneur's authentic perspective on market selection, customer understanding, business growth, and organizational development—tailored for new business leaders, corporate planners, and executives seeking the next discontinuous growth opportunity.

Talk Topics (Examples)

・How We Discovered the Market - Why we chose the fashion rental market - How we identified customer pain points

・What We Believed In, Despite No Clear Answer - Early signals before PMF (Product-Market Fit) - Approach to hypothesis validation - How we addressed opposing opinions

・How We Cultivated the Market - Educating the market in an era without fashion rental - Building systems to scale the business

Recommended For

・New business leaders and development officers responsible for 0→1 ventures

・Corporate planners and executives exploring "discontinuous growth opportunities" beyond existing businesses
