About Crassone

Crassone Co., Ltd. operates as a key player in the construction technology sector, addressing Japan's significant vacant housing problem through its demolition work DX (Digital Transformation) platform. Founded in April 2011 by Teppei Kawaguchi, the company is headquartered in Nagoya, Japan. Mr. Kawaguchi's background as a top-performing sales representative at Sekisui Heim, a major Japanese housing manufacturer, provided him with direct insight into the structural inefficiencies of the housing and demolition industry. This experience was foundational to his decision to establish Crassone, with the goal of revolutionizing an industry characterized by opaque pricing and multi-layered subcontracting structures.

The company's core business revolves around its online matching platform, "Crassone," which directly connects property owners (clients) with a nationwide network of over 2,000 professional demolition companies. This service caters to individuals needing to demolish buildings, often vacant homes, by providing transparent, multiple-quote comparisons. The business model bypasses traditional intermediaries, thereby tackling the issue of inflated costs caused by intermediary margins. Revenue is generated by charging a success fee to the construction companies upon contract agreement. By digitizing the entire process from estimate comparison to electronic contract signing, the platform offers a streamlined experience for property owners who may be unfamiliar with demolition procedures.

Crassone's platform is more than a simple matching service; it's a comprehensive digital tool for the demolition value chain. A key feature is the AI-powered "Demolition Cost Simulator," which provides instant cost estimates based on property data, addressing a major point of uncertainty for owners. The platform also includes customer reviews and quantitative evaluations of contractors across several criteria, ensuring reliability and quality. Beyond individual property owners, Crassone actively collaborates with local governments to tackle the national empty house crisis, which has seen the number of vacant homes rise to a record 9 million. Its initiatives, such as the "Sumai no Shukatsu Navi" (End-of-life home planning navigation) portal and other tools, have been adopted by over 140 municipalities and recognized by Japan's Ministry of Land, Infrastructure, Transport and Tourism as a model project for vacant home countermeasures for three consecutive years.
