Rewriting the Rules of Gas Sensing: Why We Invested in FaradaIC

Breaking Open a Multi-Billion Market

The €3.3 billion gas sensing market is overdue for a shake-up. Gas sensing technology has been running on borrowed time. Despite being essential across industries — food logistics, medical devices, industrial IoT, consumer electronics, and more — electrochemical sensors have remained largely unchanged for decades.

The core issue? They rely on liquid electrolytes, which prevent miniaturization and limit scalability. The result is sensors that are bulky, inefficient, power-hungry, and costly, making them incompatible with the demands of modern, high-volume applications.

Yet the demand for gas sensors has never been greater. As industries push toward smaller, smarter, and more integrated devices, they need sensors that can keep up. FaradaIC is delivering exactly that — a scalable, chip-based electrochemical sensor that changes everything.

A Step-Change in Sensing Technology

FaradaIC has developed MECS™ (Micro Electro Chemical Systems) technology, pioneering the miniaturization of electrochemical sensors for the first time. Instead of liquid electrolytes, MECS relies on a solid-state ion-conductive polymer, making it compatible with semiconductor manufacturing. This is a fundamental shift — electrochemistry, now manufacturable at scale, using standard MEMS fabs. No specialized equipment, no idiosyncratic processes — just better, smaller, scalable sensors built for the real world.

This isn’t an incremental upgrade — it’s a MEMS-style revolution for electrochemistry. Just as MEMS miniaturized electromechanical components, MECS miniaturizes electrochemical devices. Gas sensors are just the beginning. This technology has the potential to unlock entirely new applications, from next-generation breath diagnostics to industrial automation and environmental monitoring.

That’s why JOIN Capital led FaradaIC’s €4.5M round, alongside Forma Prime, the European Innovation Council, Elev8, Atlantis-Ventures, Tiburon, and Frontures. We invest in deep tech that leads, scales, and lasts — and this is exactly that.

The Right Team to Build It

A breakthrough technology is only as strong as the team behind it. FaradaIC is led by Dr. Ryan Guterman and Dr. Alexey Yakushenko, two founders with deep expertise in electrochemical devices, semiconductors, and materials science.

• Ryan has spent over a decade working on ion-conductive polymers and electrochemical devices at Max Planck and beyond. His work forms the foundation of FaradaIC’s solid-state electrolyte innovation.
• Alexey brings a wealth of experience from Fraunhofer EMFT, specializing in semiconductor technology and electrochemistry, making him uniquely positioned to bridge the gap between scientific innovation and scalable production.

Together, they’ve built a robust patent portfolio protecting both the material innovation and the sensor miniaturization through photolithography, ensuring long-term defensibility.

The commercial traction is just as strong — FaradaIC technology is already in the hands of more than ten major customers in the form of demonstrator devices & sensors. This year, the company will move into pilot phases with many of them, with first large-scale purchase orders expected in 2026.

Scaling isn’t a question of “if” but “how fast.” With Fraunhofer EMFT manufacturing agreements in place, FaradaIC is set up to scale from thousands to millions of sensors per year, with a roadmap to bring costs down by more than 10x as production scales.

Why We’re Backing FaradaIC

But FaradaIC isn’t just competing with legacy players — it’s redefining the space. By turning electrochemistry into a scalable semiconductor technology, they aren’t just improving existing solutions — they’re unlocking entirely new markets and applications.

From breath diagnostics and environmental monitoring to consumer electronics, food logistics, and industrial automation, the impact of scalable electrochemical sensing will be massive. Faraday Ox™, their first commercial sensor, is already proving its market fit, and Faraday Breath™ — a dual O₂ and CO₂ sensing chip — will expand their reach even further.

At JOIN Capital, we don’t invest in trends — we invest in deep tech that leads, scales, and endures. FaradaIC is exactly the kind of company that builds the backbone of the future, and we’re excited to be part of their journey.
