DOORS

What DOORS does

DOORS Inc. is a Tokyo-based platform company, founded June 2, 2014, that operates Japan's largest matchmaking platform for exterior wall painting and reform services. Its flagship product, "Gaiheki Madoguchi" (外壁塗装の窓口), connects individual property owners seeking exterior painting work with a curated network of over 6,000 registered contractor stores across Japan, supported by a proprietary database of more than 5,500 contractor companies updated annually with qualifications, staff, and performance data. The platform has served approximately 700,000 cumulative users and intermediates an annual transaction volume exceeding ¥4 billion, operating within a fragmented Japanese reform industry estimated at over ¥5 trillion in total addressable market.

The company extends its platform-plus-services model through two complementary offerings: "Gaiheki Madoguchi Reform Workshop" (wallpaint.jp), a network of community-based direct-operated reform stores that combine online convenience with local trust, and "Gaiheki Madoguchi PRO" (pro.wallpaint.jp), a B2B outsourcing service that allows contractor partners to delegate their reform operations — including consolidated consultation intake and DX-enabled construction management — to DOORS. The company holds a Tokyo Metropolitan Governor construction business license covering multiple construction categories including painting, waterproofing, tile work, and interior finishing.

DOORS generates revenue primarily through transaction-fee matching between homeowners and registered contractors, supplemented by managed-services revenue from the PRO outsourcing offering. End-user consultation and lead-matching is provided free of charge, with the platform monetizing through contractor-side partnerships. The company is a consolidated subsidiary of Nifty Lifestyle Co., Ltd. (TSE Growth: 4262), which provides corporate backing and capital access. Distribution relies on a content-led SEO strategy covering housing renovation subsidies for all 47 Japanese prefectures, paid behavioral targeting across Google, Yahoo! JAPAN, LINE, Facebook, Criteo, and affiliate networks, supplemented by free phone consultation (0120-945-990) and a partner-facing portal (gaiheki.support/ads).

Emerging players

• BuildZoom: BuildZoom is a U.S. construction marketplace connecting homeowners with contractors. It overlaps with DOORS in the matchmaking-plus-contractor-vetting concept but focuses on larger remodeling projects rather than periodic exterior maintenance.
• Renosy (GA technologies): Renosy is a Japanese proptech/renovation platform offering matched renovation services alongside real estate transactions. Comparable to DOORS in leveraging data-driven matching for renovation decisions in the Japanese homeowner market, though with a different primary acquisition channel (real estate purchase).

Others

• Procore Technologies: Procore is a leading construction management SaaS platform serving contractors. Relevant as a potential strategic comparator for DOORS' PRO B2B outsourcing service that involves DX-enabled construction management for partner contractors, though Procore sells software rather than operating a consumer marketplace.

Direct peers

• Reform Suumo (Recruit Co., Ltd.): Reform Suumo is the home renovation marketplace arm of Recruit, the dominant Japanese matching platform operator (also behind Suumo real estate and Hot Pepper Beauty). Directly comparable to DOORS as both operate two-sided marketplaces connecting homeowners with renovation/painting contractors in Japan, with similar GTM (content/SEO, free estimates, vetted partner networks).
• Houzz Inc. Houzz operates a global home renovation and design platform combining marketplace/lead-gen with content (ideabooks, professional directories). Comparable to DOORS' content-led marketplace approach and its extension into adjacent home categories beyond a single trade.
• Angi Inc. (formerly Angie's List / HomeAdvisor): Angi is the leading U.S. home services marketplace connecting consumers with prescreened local service professionals. It is the closest international analogue to DOORS' platform-plus-direct-services model, monetizing via contractor leads and advertising with a similar two-sided marketplace structure (now combining Angi Leads and HomeAdvisor businesses).
• Hipages Group: Hipages is an Australian-listed home services marketplace connecting homeowners with tradies (tradespeople). It directly mirrors DOORS' two-sided marketplace model with vetted contractor networks, transaction-based lead monetization, and recurring B2B SaaS revenue (hipages tradie subscription).

Broad incumbents

• LIFULL Connect (旧: iemo / LIFULL HOME'S): LIFULL operates major Japanese home-related platforms (HOME'S real estate, iemo renovation leads). Comparable as a broad home services content-and-matching incumbent in Japan, though not specialized in exterior painting.
• Suumo (Recruit Co., Ltd.): Suumo is the flagship Japanese real estate and home services portal of Recruit with massive scale and content depth. While broadly competing for homeowner attention and renovation intent, it is a much larger horizontal incumbent rather than a specialist in exterior painting matchmaking.

Regional players

• Nichiden-Gumi / Reform Concierge aggregators: Regional Japanese renovation aggregators and concierge platforms that operate similarly scoped matchmaking businesses but at smaller scale. Included as adjacent reference comparables for category structure, though with limited publicly available scale data for direct benchmarking.
