Ietty

What Ietty does

Ietty is a Tokyo-based, privately-held proptech startup founded in 2012 that operates an online platform aimed at home hunters in Japan. The platform is built on proprietary, in-house-developed AI and chatbot technology designed to engage prospective buyers and renters in conversational property search, narrowing listings to those that match stated criteria. The company is led by founder and CEO Taihei Ogawa, with Takemi Ohama serving as Head of Technology, and operates with a headcount of 51-100 employees as of the most recent data.

Ietty has raised approximately $6.24M across four disclosed funding rounds spanning 2013 to 2017, drawing a mix of venture capital, strategic corporate, and financial-institution investors including iMercury Capital, Incubate Fund, YJ Capital, Investors Cloud, Robot Home, Dentsu Digital Holdings, Mitsui Sumitomo Insurance Venture Capital (MSIVC), Mizuho Capital, Sansei Capital, and — in its 2017 round — strategic backers CENTURY21 Japan and ITOCHU Corporation. The investor mix reveals a B2B2C orientation, with partnerships to established Japanese real-estate distribution channels layered on top of the direct consumer platform.

The business model combines a direct-to-consumer home-hunter interface with B2B distribution through Japanese real-estate incumbents (notably CENTURY21 Japan's franchise network and Robot Home). Public information on pricing, monetization mechanics (lead-generation fees, SaaS subscription, transaction commissions, listing fees), product surface beyond the chatbot, customer count, and revenue is unavailable in the source data — the company's public-facing WordPress blog is set to private, and ietty.co.jp is not crawlable in this dataset. No patents, awards, certifications, regulatory actions, or M&A activity are disclosed.

Direct peers

• LIFULL: LIFULL operates Japan's largest online real estate and housing search portal (formerly HOME'S) and Homes.co.jp. It is the closest direct competitor to Ietty given the same Japan-focused online home-hunting vertical.
• SUUMO (Recruit): SUUMO, operated by Recruit, is Japan's dominant housing and real estate search platform across rental and purchase. It competes with Ietty for the same Japanese home-hunter audience and listing supply.
• AtHome: AtHome runs a major Japan-focused real estate listing portal serving both rental and sale markets, with strong agency relationships. It is a direct competitor in the same online home-discovery vertical.

Broad incumbents

• Yahoo!不動産 (LY Corporation / Yahoo Japan): Yahoo!不動産 is a Japanese real estate search portal offered by a major general internet platform. It competes with Ietty for traffic and listing visibility from incumbent-portfolio strength rather than specialization.
• Rakuten Real Estate: Rakuten Real Estate is part of Rakuten's broader marketplace ecosystem. It offers Japan-focused property search as one component of a larger platform, overlapping directly with Ietty's core offering.
• Redfin: Redfin is a U.S. tech-enabled real estate brokerage with a strong search portal. Its combination of listing tech and brokerage services makes it a useful benchmark for AI-driven buyer tools, though the U.S. market dynamics differ from Japan.
• Zillow Group: Zillow is the largest U.S. online real estate marketplace and a global PropTech benchmark. While geography differs, Zillow's vertically specialized search/discovery model is the global analogue for Ietty's platform model.
• Compass: Compass is a U.S. tech-enabled real estate brokerage platform. Its agent-facing and consumer-facing tools are a useful incumbent analogue for Ietty's hybrid AI/data-driven approach to home hunting.

Emerging players

• Doorstead: Doorstead is a tech-enabled property management startup using data-driven tools to streamline residential real estate services. It is an adjacent emerging PropTech comparable in applying technology to consumer-facing real estate workflows.
• Mitula Group (LIFULL group): Mitula is a vertical search engine for real estate, cars, and jobs that was acquired by LIFULL. It validates the vertical-search business model that Ietty pursues at the country level.
