LOS ANGELES — Xpanner raised $18 million in Series B funding on Tuesday to expand its autonomous construction technology as the United States faces a shortage of 349,000 workers by 2026. The California-based startup retrofits existing machinery to help contractors build solar farms, data centers, and battery storage facilities without buying new equipment.
Founded in 2020, the company developed the X1 Kit hardware control unit and AI processor to transform traditional pile drivers into automated systems. Contractors pay for the technology through a subscription model, allowing them to automate piling and material handling tasks across active job sites.
Since entering the US market in 2023, Xpanner has partnered with 19 of the top 20 engineering, procurement, and construction firms, including Mortenson and Black & Veatch. The company said its revenue surged from $3 million in 2023 to a projected $60 million in annual recurring revenue by the end of 2026.
Xpanner achieved its first operating profit in the first quarter of 2026, generating $8 million in revenue during the period, according to company statements. The firm did not disclose the names of the specific investors who participated in the $18 million Series B funding round.
Looking ahead to late 2026 and beyond, Xpanner plans to expand its automation capabilities beyond solar piling into battery energy storage projects and AI data center construction.
