What Axle Energy does

Axle Energy is a London-based energy flexibility platform that connects distributed home energy assets — including EV chargers, heat pumps, and home batteries — to European electricity markets. Founded in 2022 by Karl Bach and Archy de Berker, the company operates a cloud-based, API-first platform that aggregates behind-the-meter flexibility and dispatches it into local and national balancing, capacity, and flexibility markets. Its technology stack includes per-household probabilistic forecasting models, a daily battery dispatch optimisation engine, continuous EV charging re-optimisation, and direct credentialed OEM cloud integrations. The platform exposes modular APIs, pre-built frontend components, a whitelabel app, and a Stripe-powered user payments portal, enabling partners to embed flexibility services within days rather than months.

Axle serves two primary B2B customer segments: energy suppliers and OEM manufacturers. Energy suppliers (e.g., Good Energy, SYNC Energy, Mixergy) use the platform to aggregate flexible demand and build customer-facing flexibility propositions, while OEMs (FoxESS, SolaX, Solis, GivEnergy, Sigenergy, SolarEdge, Myenergi, Deye, Pod Point, Monta, Duracell) integrate Axle's VPP backend to monetise their installed base of batteries and chargers. Revenue is generated through a combination of API access and integration fees (subscription), transaction fees on flexibility market participation, and managed services for user reward payouts. As of mid-2024, the platform managed over 15,000 connected assets totalling more than 85 MW of capacity, with Axle claiming over 1 GW of portfolio flexibility capacity.

The company has raised $11 million across two rounds — a $1.6M pre-seed in June 2023 (led by Picus Capital and Eka Ventures) and a $9M seed in August 2024 (led by Accel). It operates across the UK and broader European markets, holding trading licenses that enable assets to participate in flexibility markets across multiple jurisdictions. The company has been recognised externally via a #1 ranking in Futurice's Electric 40 (E40) 2026 report for UK eMobility companies. Headcount sits in the 11-50 range with active hiring, and the company is privately held with no disclosed parent.

Core offering

Axle Energy provides a software platform that connects distributed home energy assets—including EV chargers, heat pumps, and home batteries—to electricity flexibility markets. The platform offers an API-first infrastructure that enables energy suppliers and original equipment manufacturers (OEMs) to optimize and trade the flexibility of customer energy assets in European wholesale and balancing markets.

Product overview

Axle Energy offers a modular energy flexibility platform with two primary product lines: (1) The Axle API and core platform enabling energy suppliers and OEMs to connect distributed assets (EV chargers, heat pumps, home batteries) to European flexibility markets; and (2) Consumer-facing products including Axle VPP for home battery owners, Smart Charging and Flex Lite for EV charging optimization, and a whitelabel-ready app. The platform's modular architecture allows partners to use individual API modules, pre-built frontend components, or the full whitelabel app. Core AI-powered capabilities include probabilistic forecasting, daily schedule optimization for batteries, and continuous re-optimization for EV charging.
