Xpanner Secures $18M to Transform Construction with AI Robots and Subscription Automation

Xpanner, a California-based construction tech startup, has raised $18 million in a Series B bridge round.

The funding, led by Korea Investment Partners with participation from KB Investment Co., brings the company's total capital to $38 million since its 2020 founding.

Retrofitting Heavy Machinery for Autonomy

Xpanner's flagship X1 Kit retrofits existing construction equipment with hardware and software to enable autonomous operations like piling and grading.

Customers access these capabilities through an innovative Automation-as-a-Service model, subscribing to task-specific licenses without massive upfront investments.

Seasoned Founders Drive Rapid Growth

Co-founders Henri Lee, David Shin, and Ryan Park bring decades of experience from giants like Bobcat, Hyundai Infracore, and Volvo Construction Equipment.

The company reports explosive revenue growth, from $3 million in 2023 to $21 million in 2025, with Q1 2026 already at $8 million and positive EBIT.

Booming Physical AI Meets Labor Challenges

This raise comes amid a surge in physical AI investments, topping $37 billion globally in 2026, as the sector tackles construction's chronic labor shortages.

Early adopters like Mortenson and Black & Veatch highlight real-world validation, with gross margins exceeding 80% and near-zero churn.

By shifting construction toward software-like scalability, Xpanner could lower costs and boost safety for everyday projects, from homes to infrastructure.

Looking ahead, the startup plans next-gen AI hardware, data infrastructure expansion, and entry into battery storage and AI data center builds.

A non-obvious angle: Korean venture firms' bet underscores Asia's growing role in funding U.S. contech, bridging manufacturing expertise with American innovation.

Ultimately, this funding signals a tipping point where AI robotics make construction faster, greener, and more accessible to the average builder.
