SparkCharge

The company's core business revolves around a Charging-as-a-Service (CaaS) model, which bypasses the need for fixed, grid-tied charging stations. This is particularly attractive to commercial fleets, which are SparkCharge's primary clients, including industries like last-mile delivery, auto OEMs, rideshare services, and ports. Revenue is generated by bundling capital expenditures, operating expenses, and energy costs into a fixed rate, allowing fleet operators to manage and forecast their charging costs without significant upfront investment. The company also leases its portable charging units to businesses.

SparkCharge offers a suite of mobile, off-grid DC fast charging solutions. Their flagship product, "the Roadie," is a modular, portable battery system that can be stacked to deliver the required amount of charge. These units are designed to be deployed rapidly, getting fleet operations running in days instead of the months or years it can take to install permanent infrastructure. The company provides several service models: Mobile Battery Charging (80-300 kW) delivered directly to fleets, a higher-capacity Off-Grid Power Hub (180-500 kW) for larger-scale needs, and a pathway to Permanent EV Infrastructure that starts with their mobile services. Service can be full-concierge, self-managed, or a hybrid. For individual EV owners, the company developed the Currently app, which allows them to request charge delivery on-demand.

Significant milestones for the company include a successful appearance on "Shark Tank," where they secured a $1 million investment from Mark Cuban and Lori Greiner. SparkCharge has raised a total of $107 million over 13 funding rounds, with the latest being a $15.5 million Series A round in May 2025. The company has delivered over 4 million kWh of power to customers and has established partnerships with major companies like Kia Motors, Hertz, and AAA. In 2025, it was selected as the EV Charging Partner for the Masters Tournament.
