NOX Energy

What NOX Energy does

NOX Energy is a Belgium-based software company (Antwerp, founded 2024) that operates a cloud-to-cloud API platform connecting residential energy assets - heat pumps, solar inverters, and (forthcoming) batteries - to wholesale, ancillary, and congestion-management energy markets. The platform abstracts device-specific manufacturer APIs behind a single REST interface (api.noxenergy.com/v1/devices) supporting 20+ brands including Bosch, Daikin, DeWarmte, LG, Midea, Mitsubishi, NIBE, Viessmann, Samsung, Vaillant, and Bulex. Core technical components include flexibility-steering algorithms, predictive day-ahead market forecasting, weather-based predictive control, comfort-preserving baseline calculations, and automated trading strategies that dispatch residential flexibility while preserving end-user comfort.

The company operates a multi-segment go-to-market. For utilities and energy suppliers (including beta partners Energy Knights, Trevion, Eneco, and Mega), NOX provides a B2B platform for residential flexibility management covering asset management, forecasting, dispatch, portfolio management, real-time monitoring, and revenue settlement, with whitelabeled app options and pre-built UI components. For OEMs (heat pump and inverter manufacturers), the company offers integration partnerships with revenue sharing on devices that participate in energy flexibility markets. For individual homeowners, NOX runs a free consumer self-serve product at app.nox.energy, monetized indirectly through energy supplier partnerships that pay for accurate consumption predictions. Distribution includes a direct consumer self-serve motion, enterprise field sales to utilities and OEMs, and a channel partnership with Belgian HVAC installer network FACQ (€25 per connected heat pump, capped at 500). The company has approximately 9 employees and is backed by Volve Capital, Seeder Fund, ERA, Golden Egg Check Capital, and Why Commit Capital, plus a AU$1.51M ARENA grant for Australia EV fleet expansion.

Revenue model

1. B2B Platform Licensing (Utilities): Provides utilities with a complete platform for managing residential flexibility, including asset management, flexibility forecasting, dispatch, real-time monitoring, and revenue tracking. Utilities pay for platform access to create new revenue streams from demand response.
2. OEM Integration Partnership: Heat pump and inverter manufacturers integrate with NOX platform, earning revenue sharing from every device that participates in energy flexibility markets. Partners track performance and payments through a partner dashboard.
3. Energy Market Trading Participation: Platform trades residential flexibility on wholesale, ancillary service, and congestion management markets. Revenue generated from grid operators paying for consumption flexibility is shared with participating households.
4. Free Consumer Tier (Lead Generation): Free service for homeowners monetized through energy supplier partnerships. Suppliers pay NOX for accurate consumption predictions that enable them to optimize electricity purchasing.

Core offering

NOX Energy builds a cloud-based SaaS platform that connects residential energy assets (heat pumps, solar inverters, batteries) to wholesale energy markets via a unified API supporting 20+ device brands. The platform enables utilities and OEMs to manage residential flexibility portfolios for demand response, grid balancing, and market trading without requiring hardware installation. Individual homeowners can use a free consumer app to optimize energy costs and participate in grid flexibility programs.

Product overview

NOX Energy is a B2B software-as-a-service platform connecting residential energy assets to energy markets. The core NOX Energy Platform provides a unified API connecting 20+ heat pump and inverter brands (Bosch, Daikin, DeWarmte, LG, Midea, Mitsubishi, NIBE, Viessmann, Samsung, Vaillant, Bulex) via cloud-to-cloud integration without hardware. The platform comprises the Asset Info API for device connectivity, Flex Availability System for real-time flexibility calculation, Portfolio Steering for intelligent baseline and comfort management, and Optimized Market Trading for day-ahead forecasting and imbalance response. Two customer-facing products target distinct segments: the Platform for Utilities enables energy companies to manage residential flexibility with solar curtailment, heat pump control, whitelabeled apps, and prebuilt UI components; the Platform for OEMs allows device manufacturers to add energy flexibility capabilities. For individual consumers, the Consumer App connects heat pumps via a simple 3-step process to optimize self-consumption, shift to dynamic tariffs, and participate in grid balancing for bill credits. The Beta Program provides early access with partner utilities, while the FACQ Installer Partnership incentivizes professional installation. All products operate on a cloud-to-cloud architecture, distinguishing NOX from hardware-based competitors.

• Sympower: Sympower is a Dutch-based flexibility service provider that aggregates commercial and industrial assets and increasingly residential flexibility for European TSO markets. It is comparable to NOX as a European-focused flexibility aggregator targeting utility and grid operator customers.
• AutoGrid (Uplight): AutoGrid, now part of Uplight, provides a VPP and flexibility trading platform that aggregates distributed energy resources for grid services markets. Comparable to NOX in trading residential flexibility on wholesale and ancillary service markets.
• Enode: Enode is a Norwegian energy API platform that connects to a wide range of residential energy devices (EVs, batteries, heat pumps, solar inverters) and exposes them to energy markets and apps via a unified API. It is the most direct competitor to NOX in the multi-brand residential energy asset aggregation space.
• Piclo: Piclo is a UK-based independent flexibility marketplace and matching platform connecting DERs to local flexibility markets run by DSOs. Comparable to NOX on the market participation and trading side of residential flexibility services.

Broad incumbents

• Tibber: Tibber is a Norwegian digital energy retailer operating across the Nordics and parts of Europe (including the Netherlands) with dynamic pricing and smart home integrations. It is comparable to NOX on consumer-facing dynamic tariff optimization and shares the same European footprint.
• SolarEdge: SolarEdge is a global solar inverter and energy management hardware/software company with its own optimizer and monitoring platform, including grid services. Comparable to NOX as a residential energy management provider, but with proprietary hardware rather than an API-aggregation model.
• Octopus Energy: Octopus Energy is a large UK-based energy retailer with in-house flexibility products (Octopus Intelligent, Kraken platform) and significant residential DR/VPP capability. It operates in adjacent space to NOX with much broader scope, including as a potential customer or competitor.
