BeFC offers data opportunities without the downsides of a battery by providing a sustainable paper-based biofuel cell and ecofriendly microelectronics. Data helps us make evidence-based daily decisions with objective and reliable information. From industrial logistics to the health of the population, BeFC products and services facilitate the implementation of a digital interface using an active sensing platform with the aim of securing supply chains, optimising workload, and improving safety. This is achieved whilst simultaneously reducing the cost, the environmental impact and the risks linked to customer activities.

‍"This significant financing round is critical for BeFC to take the next step to industrialisation. We are thankful to have strong commercial and technical investors in our lead investor Otium Capital along with the continued support of Demeter, BNP Paribas Développement and Supernova Invest."  – Dr. Jules HAMMOND, CEO & Cofounder of BeFC.

Following the €3M seed round in 2020, and with significant non-dilutive financial support from Bpifrance and Ademe, BeFC was able to construct pilot production facilities in France, reinforce its IP portfolio with over 30 patents (5-fold increase), build a talented team, and demonstrate use cases across various market verticals. day, this Series A round will allow BeFC to deliver its mission of low-cost and low-environmental-impact electronics by consolidating its strategy and pursuing its growth trajectory towards mass production. BeFC will use its resources to boost customer engagement and target new market segments within their scope of performance and long-term interest. With an established team of 45, and the objective of deploying the technology internationally to North America and Asia, BeFC will further reinforce the team with experienced industry disruptors.

An innovative alternative to current miniature batteries

BeFC invented ecological biofuel cells that are paper-based, ultra-thin, and flexible. Inspired by implantable technologies, their core technology revolves around the use of biocatalysts to convert natural biofuels (glucose and oxygen) into electricity. The biofuel cells can even be activated with environmental or biological fluids including sweat, blood, and urine.

BeFC® products : a sustainable paper energy and an ecofriendly electronic tag.

In addition, BeFC develops an active electronic sensor tag capable of collecting a range of sensor measurements (temperature, humidity, etc.) and transmitting the data wirelessly using several different protocols (NFC, BLE, Sigfox...).

Labels and awards

The disruptive and innovative technology of BeFC has resulted in numerous accolades including:

Scaling up

Based in the French deep tech ecosystem of Grenoble, over the past 2 years BeFC has focused on the industrialisation of their core technology. Transitioning to an ink-based system to leverage high throughput printing technologies, by the end of 2024 the objective is to reach a production capacity of 1 million units per day.
