Xpanner Raises $18M for Construction Site Automation-as-a-Service

Xpanner, a Santa Fe Springs, California-based startup specialising in construction robotics and physical AI, has successfully raised $18 million in a Series B bridge round. The financing was led by existing investor Korea Investment Partners (KIP), with participation from KB Investment Co. This latest infusion brings the company's total capital raised to $38 million since its inception in 2020. Originally founded in South Korea before relocating its headquarters to the U.S. in 2023, Xpanner is positioning itself as a leader in the rapidly growing physical AI sector, which has already attracted over $37 billion in global venture funding in 2026.

The 'X1 Kit' and Automation-as-a-Service (AaaS)

Unlike competitors that focus on building entirely new autonomous machines, Xpanner’s strategy centres on retrofitting existing heavy equipment. Its flagship product, the X1 Kit, allows contractors to turn their current fleet into automated assets without the need for capital-intensive "rip-and-replace" strategies. Through its unique Automation-as-a-Service (AaaS) model, customers subscribe to task-specific licenses for various operations:

• Piling and Material Handling: Automated precision for foundational work and logistics.
• Trenching and Grading: AI-driven earthmoving that reduces project durations and manual labour costs.
• Software-Led Scaling: Much like a smartphone, the machinery gains new capabilities through simple cloud-based software updates rather than hardware redesigns.

Financial Performance and Path to Profitability

Xpanner has demonstrated exceptional commercial traction, with revenue leaping from $7 million in 2024 to $21 million in 2025. In the first quarter of 2026 alone, the firm recorded $8 million in revenue and $1 million in EBIT. Maintaining gross margins above 80%, the startup is currently targeting an Annual Recurring Revenue (ARR) of $60 million by the end of the year. According to CFO Ryan Park, the subscription model allows for incremental revenue to flow at near-zero marginal cost once the initial hardware kit is deployed.

Leadership and Strategic Verticals

The company’s growth is anchored by a founding team with deep roots in the heavy equipment industry. CEO Henri Lee and CFO Ryan Park both held executive roles at Bobcat and Hyundai Infracore, while CTO David Shin spent 20 years leading robotics at Volvo Construction Equipment. This domain expertise has secured a high-tier client roster including Mortenson, Black & Veatch, and QCells. Moving forward, Xpanner plans to utilize the new capital to expand its physical AI infrastructure and enter adjacent high-growth verticals such as AI data center construction and battery energy storage systems (BESS).

Market Impact: 'Software Economics in a Hardware Market'

Investors note that Xpanner has successfully bypassed the traditional scalability wall of construction automation by focusing on task-specific software rather than end-to-end machine manufacturing. Kiho Lee of KBIC described the venture as a rare "software-economics business" operating within a hardware-dominated market, allowing for rapid account expansion with minimal proportional cost. With near-zero churn and a transition to a full subscription-only model expected by late 2026, Xpanner is redefining the PropTech and robotics landscape, providing the "business agility" required for the next generation of industrial infrastructure.
