LIFULL Achieves Record Efficiency Gains with Generative AI Utilization in Business Operations

LIFULL's Generative AI Initiative: A Game Changer in Business

株式会社LIFULL, headquartered in Chiyoda, Tokyo, has successfully harnessed generative AI within its operations, leading to remarkable efficiency gains. Over the past six months, the company reported a record creation of approximately 50,000 hours of productive time. This achievement is attributed to a surge in both the number of employees utilizing AI and the frequency of AI usage in their workflows. In fact, the percentage of employees utilizing generative AI has risen to an impressive 96.2%, marking a significant increase of 2.7 times over the past two years.

New Initiatives with Generative AI

The push for generative AI at LIFULL has been driven by a dedicated cross-departmental project team. While the project has yielded positive results in terms of efficiency, challenges remain. These include enhancing contribution to business performance, fostering a skilled workforce adept in AI, and providing tailored AI support that aligns with the unique characteristics of different roles and departments.

To tackle these challenges, the company announced the establishment of the "AI Innovation Headquarters" in October 2025. This initiative aims to consolidate knowledge and talent in one location, allowing for the expansion of AI applications across the LIFULL Group. The focus will be on leading the integration of AI within the residential domain, particularly through the real estate information services provided by LIFULL HOME'S. The company also plans to nurture around 100 professionals capable of leveraging AI to create new value.

- Total hours created: 49,836 hours, a substantial increase of 18,240 hours compared to the previous period.

Case Study - Harnessing keelAI for Enhanced Performance

In its core business, LIFULL HOME'S, the company leverages its self-developed generative AI tool, keelAI. This tool enables high-quality analysis and proposals by streamlining the data handling process. For instance, by simply inputting URLs of extensive LIFULL HOME'S response data, the system can efficiently conduct data analysis and generate infographics. Previously, the abundance of information led to considerable delays in producing client-facing reports; however, the AI integration has enabled swift and high-caliber analysis, significantly boosting the team's proposal capabilities.

Expert Commentary from Takaishi Tsubasa, Chief AI Officer

According to Takaishi Tsubasa, LIFULL's CAIO and head of the AI Innovation Headquarters, the organization has rigorously promoted generative AI since 2023 through a combination of grassroots project initiatives and top-down strategic efforts. Their commitment to education resulted in achieving a remarkable 96% utilization rate among employees. The ability to generate around 50,000 hours of productivity in just six months is a testament to the power of the workforce's willingness to embrace transformative changes.

LIFULL aims to further enhance efficiency through AI, but the ultimate goal is to use this advanced technology to drive business growth and contribute to solving societal issues.
