"Choosing Not to Use AI Is Choosing Slow Bankruptcy": Construction Firm CEO Who Grew Sales from 200 Million to 2.7 Billion Yen Presents Strategy at Bukken-Ou Seminar

On May 25, 2026, Takuma Shirato, CEO of LIFEFUND (headquartered in Hamamatsu, Shizuoka Prefecture), spoke at the Bukken-Ou seminar titled "Construction Management x AI! Successful Cases and Future Strategies from a CEO Who Grew Sales from 200 Million to 2.7 Billion Yen." The session focused on AI-driven management in the construction industry, revealing practical applications and future prospects.

■ 90% of Construction Executives Fail to Implement AI Company-Wide
While interest in AI within the construction industry is rising, adoption remains largely limited to individual use. According to a March 2026 survey by the Construction AI Management Research Association involving 53 executives, only 9.4% of companies have successfully implemented AI company-wide, with 90.6% stuck at the individual or departmental level.

The survey highlighted that the primary barriers to AI adoption are uncertainty about priorities (51%) and the lack of successful roadmaps (45.3%). CEO Takuma Shirato warns that "choosing not to use AI as a company is choosing a slow death via bankruptcy."

■ Four Proposals for AI-Driven Management
【Proposal 1】 Integrate AI into Personnel Evaluations
LIFEFUND shifted employee motivation by identifying pain points through company-wide surveys. By linking the submission of at least six AI utilization cases to performance reviews, the company generated 422 cases within three months (January–March), creating an organization that actively accumulates knowledge.

【Proposal 2】 Environmental Infrastructure and Rules as Risk Mitigation
Leaving AI to individual usage is a major security risk. LIFEFUND established clear usage rules based on Ministry of Internal Affairs and Communications guidelines, including restricting available tools and prohibiting the entry of customer data, thereby minimizing risks.

【Proposal 3】 Generate Design Proposals in 10 Minutes Using AI
Their brand, "PG House," adopts a "sales-design" model where sales staff create designs using AI instead of architects. Tasks that previously took 2–3 weeks, including exterior renderings and floor plans, can now be completed in just 10–15 minutes, providing a significant competitive advantage.

【Proposal 4】 AI as a Management Resource
LIFEFUND positions AI as a core management resource, pursuing a strategy aimed at achieving 100 million yen in sales per employee.
