About Sumutasu

Sumutasu Inc., established in January 2018, operates in the Japanese real estate technology sector, focusing on streamlining the process of buying and selling residential properties. The company was co-founded by CEO Takahiro Sumi and Director Tomoya Ito. Sumi's background includes launching the real estate media platform "Ieul" at Speee Inc. and holding multiple roles at Itanji, experiences that directly inform Sumutasu's mission. Ito previously worked at Recruit Holdings on the "SUUMO" real estate portal and was the first senior product manager at the Japanese branch of "OYO LIFE". The company’s name, a blend of the Japanese words for "to live" (sumu) and "to add" (tasu), reflects its mission to add new value to housing.

Read full description

Sumutasu's business model is centered on the "iBuyer" concept, where the company directly purchases properties from homeowners, aiming to simplify and accelerate the traditionally complex sales process. The firm utilizes a proprietary AI-powered assessment algorithm to provide homeowners with a purchase offer, often within an hour, and can complete the transaction and cash payment in as little as two days. This approach addresses common seller pain points such as uncertain timelines, the hassle of property viewings, and negotiations with multiple parties. Revenue is generated by purchasing condominiums, renovating them, and then reselling them. The company also offers a brokerage service, giving sellers a choice between a direct, quick sale to Sumutasu or a traditional market listing.

The primary service, "Sumutasu Gaikyaku" (Sumutasu Sale), targets condominium owners in metropolitan areas like Tokyo, Kansai, and Tokai who are looking for a transparent and swift selling experience. By acting as the direct buyer, Sumutasu eliminates the need for intermediary brokerage, often waiving the associated fees for the seller. For buyers, the company operates "Sumutasu Chokuhan," a portal for purchasing these renovated condominiums, also without a brokerage fee. The company has achieved significant traction, with cumulative property assessment requests surpassing 40,000, valued at over 1.13 trillion yen as of July 2024. Sumutasu has secured substantial funding through multiple rounds, including a Series C round of 1.3 billion yen and a recent debt financing of 2.2 billion yen, bringing its total raised capital to over 3 billion yen.
