What HOMMA does

HOMMA Group Inc. is a privately-held smart home technology company founded in 2016 in Silicon Valley that develops a proprietary software platform called Cornerstone OS combined with custom hardware (in-wall sensors, control pads, connected thermostats, motorized shades, and keyless door locks) to deliver automated, construction-stage-integrated smart home systems. Unlike consumer-installed smart home products, HOMMA's technology is embedded into a property's architecture during construction or renovation, enabling sensor-driven orchestration of lighting, climate, shades, and door locks without requiring resident setup, app configuration, or voice commands. The flagship feature set includes circadian-aligned lighting that adjusts color temperature across five time periods of the day, occupancy detection that triggers approximately 300 automated actions per unit per day, and a unified mobile app for management. HOMMA also develops its own branded residential rental properties under the HOMMA HAUS sub-brand, which serve both as revenue-generating assets and as product demonstrations for prospective developer partners.

HOMMA's business model rests on three revenue streams: (1) B2B project-based integration fees from real estate developers for embedding HOMMA's system into new construction and renovation projects (turn-key delivery covering planning, procurement, installation, and ongoing maintenance); (2) rental income from HOMMA's owned portfolio of HOMMA HAUS properties, currently totaling approximately 48 units across two Portland, Oregon assets (Mount Tabor and Willamette Tower); and (3) recurring subscription services for ongoing software access and over-the-air updates. Reported outcomes include rental price premiums of approximately 11% above comparable properties in surrounding Oregon markets and faster lease-up of move-in-ready units. Pricing is quote-based and not publicly disclosed.

The company's primary customer segment is enterprise real estate developers and builders, both in the US (Portland and Boston markets) and Japan (Tokyo, Osaka, Okayama, Matsue). Named enterprise customers and partners include Diamond Realty Investments (Mitsubishi Corporation's real estate arm), Alamo Manhattan, Nippon Steel Kowa Real Estate, Wada Corporation, Tanabe no Mori, NTT UD USA, and Synergy Boston. In December 2025, HOMMA established a Tokyo office and entered a capital and business partnership with Iris Ohyama Inc. — a major Japanese hardware manufacturer — integrating Iris Ohyama's LiCONEX wireless technology and LED products with Cornerstone OS. The company maintains subsidiaries in Tokyo (HOMMA Group株式会社) and Seoul (HOMMA KOREA Co., LTD.), and has cumulatively raised approximately $31.9M across six disclosed funding rounds from 2016 to 2021, plus an undisclosed strategic investment from Iris Ohyama in late 2025.

Revenue model

1. Smart Home System Integration (B2B): HOMMA integrates its technology into developer-owned residential projects (new construction and renovations) for a fee. Revenue covers planning, device procurement, installation, pre-configuration, and ongoing maintenance/support. Developers benefit from rent premiums and faster lease-up, while HOMMA earns project-based fees.
2. Subscription Services (Software): HOMMA provides subscription services accessible via its mobile app. The software platform orchestrates all smart home functions and delivers over-the-air updates. Recurring subscription revenue from residents or property owners for ongoing access to the smart home experience and software improvements.
3. Direct Property Leasing (Own Portfolio): HOMMA develops and operates its own branded residential properties (HOMMA HAUS), leasing units directly to residents. Revenue is rental income. Currently includes HOMMA HAUS Mount Tabor (18 units, Portland, OR), HOMMA HAUS Waterside (sold 2020), and 30 units at Willamette Tower, Portland, OR. In Japan, the company opened a showroom targeting both B2B and B2C customers.
4. Capital & Business Partnership (Iris Ohyama): Iris Ohyama invested in HOMMA through a third-party share allocation at the end of 2025. This represents an equity investment into HOMMA, with the strategic partnership combining Iris Ohyama's LiCONEX wireless technology and LED products with HOMMA's Cornerstone OS platform for the Japanese market.
