Key Takeaways

  • The company raised $22 million to accelerate growth in ambient IoT markets
  • Crédit Mutuel Innovation and SFPIM backed the round to support semiconductor and energy-efficiency expansion
  • The funding strengthens the organization's position as demand rises for battery-free connected devices

The ambient IoT category is expanding as industries scale connected systems. To support this demand, e-peas, headquartered in Louvain-la-Neuve, Belgium, secured $22 million to broaden the reach of its energy-harvesting semiconductors. Crédit Mutuel Equity led the investment through Crédit Mutuel Innovation, with participation from SFPIM and several existing investors, underscoring rising industrial interest in low-power and battery-free electronics.

This financing aligns with a broader industry focus on energy efficiency and long-term device deployment. Technical bodies, including the IEEE, report that 802.15.4 low-rate wireless standards require new approaches to power management in energy-constrained ecosystems. As enterprises roll out massive fleets of sensors, these technical standards now directly influence corporate procurement strategies for ambient IoT technologies.

The new capital will accelerate commercial expansion, fund entry into international markets, and support a broader product portfolio for battery-free electronic systems. The company also used the funding process to streamline its shareholder structure, positioning itself for scaled production.

Crédit Mutuel Innovation’s participation fits its strategy of backing deep technology and life sciences ventures. The investor typically supports companies with €1 to €20 million in equity and manages capital through its parent group, Crédit Mutuel Equity, which oversees about €5 billion. SFPIM, managing roughly €12 billion, added its support to back Belgium-based companies in strategic sectors tied to national priorities, including the energy transition and advanced technology.

The drive toward ambient IoT stems from concrete operational challenges. Analysis by McKinsey indicates that as IoT projects move into large field deployments within industrial and logistics environments, device power strategies face intense pressure. Traditional battery-powered sensors create logistical and financial barriers when deployed by the millions, making frequent battery replacements practically impossible.

e-peas addresses this challenge by developing semiconductor technology that captures ambient energy from surrounding sources. Its ultra-low-power integrated circuits and microcontrollers collect energy from light, radio-frequency signals, heat, or vibration. This allows devices to operate without frequent battery replacement cycles, directly reducing operating costs. The technology currently supports applications ranging from remote controls and HVAC systems to cameras and asset-tracking devices, cutting technician hours and extending hardware lifespans.

According to Deloitte, sustainability metrics are increasingly embedded directly into enterprise procurement and engineering requirements. Energy-harvesting devices enable organizations to meet environmental targets by eliminating battery waste while maintaining reliable operations. The organization aims to move the market toward treating energy harvesting as a default design choice rather than a niche application.

The core technology relies on approximately 15 years of research and patented intellectual property focused on power efficiency. The ability to harvest ambient energy aligns with formalized ecosystem support, specifically 3GPP Release 19, which includes ambient IoT in its core specifications. This standard development indicates formal cellular ecosystem readiness for passive tags and devices with extremely low power requirements.

Diverse connectivity frameworks are adapting to accommodate these ultra-low-power deployments. The LoRa Alliance positions LoRaWAN for low-power, wide-area IoT networks, while the Bluetooth SIG’s Bluetooth LE ecosystem supports short-range asset-tracking use cases. By developing hardware that functions across these different wireless protocols, the firm integrates with the broader connectivity ecosystem rather than relying on a single network standard.

Enterprise demand is scaling as organizations deploy sensors across factories, transportation fleets, and large commercial buildings. Maintaining devices in hard-to-reach locations drives up operational overhead when technicians must be dispatched solely to swap batteries. Ambient energy harvesting minimizes these maintenance requirements, enabling long-term deployment intervals for large-scale sensor networks.

The funding will directly support the development of new energy harvesting chips and expansion into additional product categories. The organization maintains offices in Belgium, Switzerland, and the United States, positioning it to capture enterprise demand across regions where businesses are scaling zero-maintenance IoT infrastructure.

The company's CEO stated that the investment strengthens the ambition to make energy harvesting a standard option across sustainable electronics. A representative from Crédit Mutuel Innovation characterized the opportunity as a way to reshape IoT growth toward long-term sustainability. Additionally, leadership at SFPIM noted that the technology aligns with Belgium’s national priorities for deep-tech leadership and the energy transition.

The $22 million capital injection reflects formalizing institutional support for the broader ambient IoT segment. As standards like 3GPP Release 19 reach maturity and global sensor deployments expand into the millions, eliminating battery dependency is transitioning from a specialized differentiator to a baseline requirement for industrial network design.
