Fraunhofer Institute for Surface Engineering and Thin Films ISTA look behind the scences – two years of “Integrative Nanotech”
Two years have passed since Integrative Nanotech was launched as a spin-off. Since then, the company has made significant progress: what began as a technology-driven vision has grown into a company that is continuously advancing its solutions for hydrogen leak detection and bringing them to market. In close collaboration with Fraunhofer IST, key technical milestones have been achieved, partnerships have been established, and initial applications have been realized. At the same time, the team has had to navigate a range of challenges—from technological fine-tuning and regulatory requirements to building robust organizational structures. Dr. Hunter King shares insights into how Integrative Nanotech has developed over the past two years, the obstacles that had to be overcome, and the successes that have shaped the company’s journey.
Hunter, could you briefly explain what Integrative Nanotech does? What is behind the name, and what products or services do you offer?
Yes of course! Integrative Nanotech specializes in the development of high-performance hydrogen sensors. Our primary focus is the reliable detection of hydrogen leaks and, more recently, the early detection of thermal runaway in battery systems. Our core technical advantage lies in the sensor’s selectivity: it can accurately distinguish between non-critical cell venting and critical thermal runaway events, significantly reducing false alarms in electric vehicle applications and battery energy storage systems. While this remains the central focus of our organization, this just represents the first market opportunities we are looking to address. Our company name eludes to the longer term vision within our organization, that is, to bring about the next generation of sensors, powered by our proprietary commercial-scale nanomaterials.
You’ve been self-employed for almost two years now. How has that journey been for you so far?
Certainly, a lot of learning and growth like any deeptech startup company. This is my first experience as a founder, and although everything is going quite well right now it was a rather extreme learning curve. Our early problems are likely very similar to those many experiences in these fields: building strong customer relationships and understanding their pain points, finding the critical people who can help both build the product as well as the organization as a whole, and ensuring we have the capital to execute on our goals. However, we’ve received a huge amount of support from our local ecosystem partners, other experience entrepreneurs, and our early investors. This has enabled me to build out my skillset, expand and hire an incredible team, and stay focused on what truly matters; pushing the needle and building something of impact and value for the market.
What role has Fraunhofer IST played in Integrative Nanotech’s journey so far? And what are your plans for the future?
Fraunhofer IST has played a crucial role for our organization, especially in actually building our product. One typical major hurdle for many deeptech hardware startup companies is the massive requirement for capital expenditures (CapEx) to be able to actually build their product. Through our collaboration with Fraunhofer IST, we have been able to leverage both their expertise as well as their production-scale systems. This has significantly accelerated our rate of product development while reducing upfront CapEx requirements, giving us a significant market advantage. Furthermore, Fraunhofer IST has an extensive network in both the hydrogen and battery markets. This has given us opportunities to further refine our product and go-to-market strategies.
What has been your most memorable or rewarding moment at Integrative Nanotech so far?
That’s honestly a really tough question as there have been several major high points over the past few years. However, the most recent one would have to be the results from our testing with the National Research Council’s (NRC) battery performance and safety evaluation research facility in Ottawa, Canada in September of last year. This provided the first real-world validation of our technology in a thermal runaway context. The results confirmed that our sensors could reliably identify critical failure states, where existing market solutions often struggle to distinguish between non-critical venting and actual runaway (critical, requiring response/intervention).
What are your hopes or goals for the future of your company?
Of course, like any founder I aim to continue to grow our organization. But I think most important to me is to continue to build new technologies that I find exciting, which also have the potential to make huge impacts in the market.
