Xpanner has closed an $18M Series B bridge round led by Korea Investment Partners, bringing total funding to $38M since 2020. The Santa Fe Springs, California company builds retrofit automation for construction equipment sold on a subscription basis.
The core product is the X1 Kit, a hardware and software layer that bolts onto existing equipment and enables autonomous operation without machine replacement. Task-specific automation — piling, material handling, trenching, grading — are delivered as subscription licenses under an Automation-as-a-Service (AaaS) model. Customers expanding scope get new capabilities via software update, not a purchase order. KB Investment Co. (KBIC) also participated alongside lead KIP.
The co-founder lineup runs deep in construction hardware. CEO Henri Lee spent two decades at Bobcat and Hyundai Infracore running unmanned equipment initiatives. CTO David Shin led robotics and automation at Volvo Construction Equipment for 20 years and was first in the industry to commercialize semi-automation features for construction machinery. CFO Ryan Park brings 12 years in heavy equipment at Bobcat followed by eight years in venture capital. That depth shows in the customer roster: Mortenson, Black & Veatch, and QCells are production accounts, not pilots.
Xpanner grew revenue from $3M in 2023 to $7M in 2024 to $21M in 2025. Q1 2026 alone posted $8M in revenue and $1M in EBIT. The company targets $60M in ARR by year-end 2026. Gross margin sits above 80%, driven by the subscription model's near-zero marginal cost after hardware deployment. Xpanner hit monthly break-even in 2025 and targets full-year profitability in 2026. For a physical-AI play in a hardware-heavy sector, those unit economics stand apart.
KIP managing director Sangjoon Park cited "strong gross margins, near-zero churn, and rapid account expansion" as signals of a durable value proposition. KBIC director Kiho Lee spelled out the architecture: most construction automation companies hit a scalability wall by automating entire machines end-to-end, which ties growth to hardware redesign cycles. Xpanner's task-specific approach scales through software licensing inside existing accounts — expanding wallet share without proportional cost — importing software economics into a hardware-dominated market.
One caveat: a portion of Xpanner's customer base remains on a perpetual modular model — a one-time X1 Kit hardware purchase paired with software rather than a recurring subscription. The company plans to complete the transition to a fully subscription-based book by year-end. Until that migration closes, the 80%-plus gross margin reflects a mixed-model reality. No latency, throughput, or cycle-time benchmarks from autonomous operations were disclosed.
Xpanner plans to deploy capital into next-generation physical AI hardware, core component engineering, and AI/data infrastructure. The company is also entering adjacent verticals: battery energy storage systems (BESS) construction and AI data center construction — both high-velocity build environments with the same labor scarcity as commercial construction.
