SEED

What SEED does

SEED Corporation (株式会社シード・コーポレーション) is a privately held Japanese company founded in April 2007 and headquartered in Fukuoka, with regional offices in Tokyo, Osaka, and Nagoya. The company operates a specialized 24/7 call center and physical emergency dispatch network built exclusively for the residential rental property industry. Its core offering is a suite of branded membership products — Kurashi-do 24, SEED24, and Anshi-do 24 — under which residents in partner-managed properties receive single-number emergency response for water leaks, lockouts, glass breakage, electrical and gas failures, fittings repairs, and fire-safety incidents. Dispatch is executed through a nationwide network of approximately 3,200 affiliated contractor locations covering all of Japan except remote islands, and the company's proprietary でんワンSYSTEM web platform gives property managers real-time visibility into inbound calls, dispatch status, and case analytics.

The company monetizes through three complementary streams. First, recurring subscription fees from resident members on monthly or annual billing cycles, with optional 2-year payment aligned to lease terms. Second, transaction-based sales agency commissions paid to roughly 5,100 real estate management company partners who enroll tenants into the dispatch service. Third, subscription-based call center BPO contracts (Trouble Nai-Nai Desk) where SEED answers tenant calls on behalf of property management companies 24/7, with quote-based pricing tied to expected call volume. Distribution runs primarily through this agency channel, supplemented by a direct BPO field sales team of approximately 20 staff conducting door-to-door visits, plus an OEM/white-label offering that lets partners rebrand the dispatch service under their own toll-free number.

Operationally, SEED reports approximately 110 employees as of April 2024, a 95% call response rate, and a 3-year employee retention rate above 90%. The membership base has grown from 50,000 dispatch contracts in November 2011 to 600,000+ contracts by March 2026, while the agent network has scaled from 500 stores in 2009 to approximately 5,100 today. Cumulative sales revenue crossed the ¥1 billion mark in March 2019 and the ¥4 billion (40億円) mark for the fiscal year ending March 2024, with sixteen consecutive years of revenue growth. In January 2026, SEED completed the 100% acquisition of Fukuoka-based software firm AST Co., Ltd., signaling a move to internalize proprietary technology development.
