  • Mitra EV

    Led · Equity · Feb 2026

    Mitra EV delivers a fully managed fleet-electrification service that bundles vehicle leasing from OEMs such as GM, Ford, and Mercedes-Benz with overnight depot charging and access to a growing network of shared DC fast-charging hubs. Targeting the small- and mid-sized businesses that comprise 99% of U.S. fleet operators, the platform promises immediate operating-cost reductions of up to 70-75% by lowering fuel and maintenance expenses. Mitra’s model is capital-efficient for customers, requiring no upfront spend while guaranteeing cost savings from day one. The company is vehicle- and charger-agnostic, enabling flexible, future-proof deployments without locking fleets into a single hardware provider. Recent launches include the nation’s first shared DC fast-charging hub network designed for urban commercial fleets, addressing charging access constraints in dense markets. Proceeds from its latest financing will fund expansion of this charging network, additional vehicle deployments, and entry into new geographic markets. Although the article does not disclose revenue or user counts, Mitra emphasizes quick payback periods and measurable ROI for fleet customers.

  • L-Charge

    Led · Equity · Jan 2026

    L-Charge focuses on solving power-access bottlenecks for electrification by offering self-contained, modular charging units that operate independently of the electrical grid. Its flagship products enable rideshare, last-mile delivery, and broader fleet customers to deploy charging stations in weeks rather than waiting months for utility upgrades. The company monetizes through Charging-as-a-Service and Power-as-a-Service contracts that eliminate up-front capital expenditure for customers. With demand rising amid permitting delays and grid constraints, L-Charge plans to expand its national installation footprint and introduce additional product categories, particularly enlarging its portfolio of off-grid chargers. The newly secured capital will also fund growth of sales, operations, and customer-support teams to manage increasing project volumes. Although no revenue or user metrics were disclosed, management describes the company as entering a “next phase of growth,” underpinned by accelerating fleet electrification trends.
