Company Overview / Who We Are
Aucfan Co. Ltd, listed in the Tokyo Stock Exchange Growth Market, was established in 2007.
The company was first established to operate "aucfan.com," one of the largest shopping and auction market search sites in Japan.
Using AI technology and the transactional data we've accumulated from over 70 billion EC and physical store since our establishment, we have built an estimation model that visualizes the market value of products and optimizes the price and sales channels for corporate inventories.
Founded on the desire "to make people and goods happy by discovering the value of idle goods and sending them to where they are needed," we are tackling the problem of waste and inventory loss, which amounts to 22 trillion yen in Japan and 100 trillion yen worldwide.

Our Vision / Mission
~RE-INFRA COMPANY ~
Building a circulating distribution infrastructure based on AI x people to solve the world's "Mottainai" (wasteful) problem.
Since our establishment, we have grown to become one of the largest shopping and auction market search sites in Japan and have continued to expand our business with BtoB wholesale platforms and tools to improve the efficiency of collective EC operations. We are motivated by the desire to make people and goods happy by discovering the true value of idle items and moving them to the people and places they are needed.
The annual value of wasted merchandise is JPY22 trillion in Japan and JPY100 trillion worldwide. We have redefined our company as a "RE-INFRA COMPANY" because we revitalize the distribution of products by reawakening their true value. "RE" means recapturing what is already there, reconfiguring it for the better, and reconstructing it. By connecting and integrating the various "RE" functions of each service, we maximize the value of our products and deliver them to those who need them.
