Lelantos Raises Seed Funds for New Era of Gas Sensing

New York, NY and Silicon Valley, CA – October 11th 2021 – Lelantos, a developer of semiconductor gas sensors for Internet of Things (IoT) monitoring applications targeted to the oil and gas industry as well as heating, ventilation, air-conditioning and refrigeration market (HVACR), has raised seed funding to further develop and commercialize its patented gas sensing technology. Lelantos was recently awarded a National Science Foundation SBIR Phase II grant. Concurrently, Lelantos has also received funding from the Silicon Catalyst Angels, a group of early-stage angel investors based in Silicon Valley. The combination of the SBIR grant and the equity investment enables Lelantos to expand the team and move forward with their product development plan.

“Securing this initial funding is a very important step forward for the company,” said Dr. Stylianos Siontas, CEO and co-founder of Lelantos. “Our vision is to provide pervasive environmental monitoring and safe working conditions in the oil and gas, and HVACR market. We appreciate the shared commitment from these early investment groups to enable this vision.”

Lelantos was founded in 2019 by Columbia University professor, Dr. Ioannis Kymissis and Dr. Jose Bajamonde, CTO, alongside Dr. Stylianos Siontas. The foundational technology was developed in Dr. Kymissis's lab over the last 5 years. Lelantos implements a novel approach to sense the presence and identity of the target gas molecules by leveraging functionalized piezoelectric films that can be fabricated on conventional silicon microchips. This approach enables a single sensing device able to identify a myriad of target gasses while offering an unparalleled combination of size, power, and cost, enabling widespread adoption in Internet of Things (IoT) applications. The opportunity to commercialize the technology was initially enabled with the award of an NSF STTR Phase I grant in 2020.

“We are pleased to witness the strong investment support in Lelantos combined with the SBIR II grant. We have been extremely impressed by the team and their continued advancement of a technology that could have a material impact on addressing leak detection applications in the oil and gas industry. Aegex is strongly invested in this space and continually seeks innovative sensor technologies that we can support in integrating into our IoT solutions. With this milestone, we will be expanding our support and continue to commit resources to accelerate the Lelantos technical development and path to commercialization.’’ said Thomas Ventulett, CEO of Aegex Technologies, LLC a global provider of certified intrinsically safe solutions targeted to the industrial market.

In April 2021, Lelantos joined the Silicon Catalyst incubator to take advantage of the expanded design and manufacturing ecosystem. The mission of Silicon Catalyst is to lower the capital expenses associated with the design and fabrication of silicon-based IC’s, sensors, and MEMS devices. For over seven years, the Silicon Catalyst partner ecosystem has enabled early-stage companies to build complex silicon chips at a fraction of the typical cost. Additionally, the startups can tap into the world-class Silicon Catalyst advisor and investor network.

“Lelantos’ gas sensor technology addresses a critical market that is already very large and will grow dramatically in the coming years. As a Portfolio Company in our incubator, we are pleased to see that they are making great progress in executing on their commercialization plans,” said Pete Rodriguez, CEO, Silicon Catalyst.

About Lelantos
Lelantos is revolutionizing the world of gas sensing, developing a new generation of IoT compatible gas sensors targeted to high value monitoring applications in threat detection, industrial safety, environmental and air quality monitoring as well as medical diagnostics. Current gas sensors suffer from inherent weaknesses such bulky size, high power consumption and high cost. As such, they prohibit effective monitoring in IoT oriented use cases that require pervasive sensing to be provided by autonomous, battery operated sensors with wireless connectivity. In contrast, Lelantos sensors can achieve up to 1000x more compact size, lower power consumption and lower cost than currently utilized systems. With its transformative sensing technology, Lelantos is enabling the widespread adoption of gas sensing in IoT applications and the disruption of the market providing a true chemical sensor for the Internet of Things.
