Construction automation firm Xpanner has secured $18 million in Series B bridge funding to address the severe labor shortage in the US construction sector. The round, led by existing investors Korea Investment Partners and KB Investment, brings the company's total funding to $38 million. This capital will fuel the expansion of its unique subscription-based platform that retrofits existing machinery into autonomous robots.
Addressing a Structural Labor Crisis
The US construction industry is facing an unprecedented labor deficit, with an estimated 349,000 new workers needed by 2026. This shortage is intensified by a simultaneous boom in the construction of solar farms, AI-driven data centers, and battery storage facilities. These massive infrastructure projects are all competing for the same limited pool of skilled labor, creating significant project delays.
According to Xpanner CEO Henri Lee, traditional recruitment methods are insufficient to solve a structural shortfall of this magnitude. The only viable solution is to fundamentally enhance the productivity of each worker on a jobsite. This requires a technological shift that empowers smaller crews to accomplish significantly more work than was previously possible.
A Novel Approach to Automation
Xpanner distinguishes itself by not building new autonomous machines, a capital-intensive approach taken by many competitors. Instead, its flagship X1 Kit is a retrofit solution that attaches to equipment contractors already own, such as pile drivers. This hardware and AI processor combination transforms standard equipment into what the company calls Software-Defined Machinery.
The company operates on an Automation-as-a-Service (AaaS) subscription model, making advanced automation accessible without large upfront investments. Contractors pay for specific task licenses, such as piling or material handling, allowing their existing machines to operate with minimal supervision. This model generates software-like economics with gross margins reported to be above 80 percent.
Proven Traction and Profitability
Since entering the US market in 2023, Xpanner has demonstrated remarkable growth and market penetration with zero customer churn. The company has already engaged with 19 of the top 20 US solar farm EPCs, including industry leaders like Mortenson and Black & Veatch. This rapid adoption underscores the urgent need for its automation solutions in the field.
The company's financial performance has been equally impressive, achieving profitability in the first quarter of 2026 with $8 million in revenue. Cumulative revenue has surpassed $31 million, with the company targeting $60 million in annual recurring revenue by the end of the year. Sangjoon Park of Korea Investment Partners noted that few Physical AI firms achieve such commercial traction so quickly.
Future Expansion and Market Opportunity
With the new funding, Xpanner plans to expand beyond its initial success in solar farm construction. The company is now targeting the rapidly growing sectors of Battery Energy Storage Systems (BESS) and AI data center construction. These markets represent a massive runway for growth, driven by the global demand for AI-era energy infrastructure.
Investors see this strategic expansion as a key driver for future success, building upon a proven and de-risked business model. As Kiho Lee of KB Investment stated, solar piling provided the essential foothold for the company. The burgeoning BESS and data center markets now offer a significant opportunity for scalable expansion.
Xpanner's $18 million funding round highlights the market's confidence in its practical and cost-effective approach to construction automation. By converting existing equipment into intelligent machines through a subscription service, the company provides a scalable answer to the industry's critical labor crisis. As the demand for new energy and data infrastructure continues to surge, Xpanner is well-positioned to lead the charge in automating the jobsites of the future.
