What Fever does

Fever Energy AB is a Stockholm-based powertech company founded in 2021 that provides a software platform acting as an operating system for distributed energy management. The company sells to enterprise energy companies — utilities and energy service providers — under a white-label model, enabling those customers to connect, monitor, forecast, optimize, and trade heterogeneous distributed energy assets (batteries, solar PV, EV chargers, meters) under their own brand. The platform architecture is modular: a Core layer (REST APIs, a shared Data Model, Integrations, and an event-driven Orchestration engine), five functional Modules (Connect, Insight, Predict, Optimize, Trade), four role-based Interfaces (Console for operations, Field for installers/support, View for end customers, Charge for EV charging), and a proprietary Gateway hardware device that connects legacy assets lacking cloud connectivity. The Gateway ships by post, supports 100+ device types, and enables self-installation without an installer visit, materially expanding the addressable asset base for each customer.

Fever's go-to-market is sales-led and consultative, with demo-driven enterprise engagement and a quote-based pricing model. The company generates revenue primarily through platform software subscriptions to energy companies, supplemented by hardware sales of the Gateway. Named customers include Vattenfall (600,000+ households reached, 10,000+ assets, 600 MWh+ under management, 100 MW+ qualified for the balancing market), Varberg Energi (700+ BESS and 500+ PV sites onboarded, 3x homeowner revenue growth), Enequi (+30% monthly site growth, 99.9% uptime), Greenely (4,000+ EVs aggregated), and Flexecharge (500+ high-power charge points aggregated). AI/ML capabilities are focused on forecasting, anomaly detection, and portfolio optimization on telemetry data, with reported customer outcomes of +150% revenue versus the next-best optimizer in Sweden.

The company has raised approximately $21.7M across three rounds — a 2022 pre-seed led by La Famiglia with Norrsken VC, a 2024 seed of €10M led by General Catalyst with La Famiglia and Norrsken VC, and a 2025 round of ~$9.3M led by RTP Global. Use of funds is explicitly directed at expanding the virtual power plant platform across Europe from its current Swedish base. The company operates as Fever Energy AB under Swedish jurisdiction, with a team of 11-50 employees.

Product offering

Core offering

Fever provides a modular software platform, marketed as the operating system for distributed energy, that enables energy companies to connect, orchestrate, optimize, and trade distributed energy assets such as batteries, solar PV, EV chargers, and meters. The platform is sold to utilities and energy service providers on a subscription basis and is deployed under their own brand to end customers, with a complementary Gateway hardware device for legacy assets lacking cloud connectivity.

Product overview

Fever is a modular platform-plus-modules architecture serving as the operating system for distributed energy. The platform consists of a Core layer (APIs, Data Model, Integrations, Orchestration) providing the shared foundation, overlaid by five Modules (Connect, Insight, Predict, Optimize, Trade) that deliver specific capabilities, and four Interfaces (Console, Field, View, Charge) for different user types. A complementary Gateway hardware device enables connectivity for legacy assets without cloud requirements. The architecture is designed to scale from individual sites to large portfolios without multiplying operational complexity.

Fever competitors and assessment

Company assessment

Emerging players

Stem Inc: US-listed AI-driven clean energy and DERMS provider that connects and optimizes distributed solar, storage and other assets for commercial/industrial customers and utilities. Comparable on AI-driven DER optimization and orchestration platform, though primarily US-focused.
Tibber: Norwegian digital energy retailer operating across the Nordics and Europe with smart home/energy management app, dynamic tariffs and EV charging integration. Adjacent to Fever in Nordic energy ecosystem and smart-home energy use case, but operates as a retailer rather than a B2B platform.

Direct peers

Enode: Norwegian-headquartered platform that connects and orchestrates distributed energy assets (EVs, batteries, heat pumps, solar) for utilities and energy companies via APIs. Direct comparable to Fever in target customer (European utilities), operating model (white-label DER orchestration), and EV aggregation use case.
GreenCom Networks: German white-label IoT energy management platform connecting distributed energy assets (solar, storage, heat pumps, EV chargers) for utilities. Highly comparable on white-label platform model, multi-asset DER connectivity, and European utility customer base.
GridBeyond: Irish-Dutch platform combining AI-based forecasting and DER orchestration for industrial, commercial and distributed energy assets, with a focus on European flexibility markets. Direct peer on AI-driven optimization, multi-asset DER orchestration, and utility/aggregator customer base.
Piclo: UK-based independent marketplace and matching platform connecting flexibility providers (DER operators, VPPs) with system operators and flexibility buyers. Comparable as a complementary layer in the European flexibility value chain where Fever's customers participate.
Sympower: Amsterdam-based flexibility provider and VPP operator aggregating industrial and commercial DERs to provide balancing and capacity services across European TSOs. Direct comparable to Fever on VPP/DER aggregation business model and European energy-company customer base.

Broad incumbents

Limejump (Shell): UK-based flexibility platform acquired by Shell that aggregates DERs to provide balancing, capacity and ancillary services to the GB market. Comparable on DER aggregation and market participation; broader incumbent under Shell's energy services umbrella.
Sonnen (Shell): German residential battery and VPP player now owned by Shell, providing home batteries, virtual power plant aggregation, and energy services across Europe. Comparable on residential battery aggregation and VPP; broader incumbent with vertically integrated hardware and energy services.
Octopus Energy: UK-headquartered renewable energy retailer with Kraken technology platform, smart tariff products, EV integration, and growing VPP/flexibility capabilities. Comparable on European energy customer base and flexibility/dispatch capabilities, but a much larger and vertically integrated incumbent.
