Borusan Ventures Supports the Energy of the Future with Investment in Fourier

Borusan Group’s corporate venture capital firm, Borusan Ventures, continues to invest in technologies that generate energy from sustainable sources. Fourier, a U.S.-based company that develops modular electrolyzers for hydrogen production, raised $18.5 million in a Series A funding round that included participation from Borusan Ventures.

Staying true to its vision of supporting startups in its focus areas, Borusan Ventures joined the Series A funding round of Fourier, which develops modular electrolyzers for hydrogen generation. The round, led by General Catalyst and Paramark Ventures, also saw contributions from investors such as Airbus Ventures, MCJ, GSBackers, and Positive Ventures.

Headquartered in Silicon Valley, Borusan Ventures invests in early-stage startups in the U.S. and Europe, focusing on energy, mobility, logistics, supply chain, and industrial technologies. Leveraging Borusan Group’s over 80 years of industrial experience, Borusan Ventures provides strategic support to help startups achieve global success and long-term impact, while also offering access to new markets and growth opportunities.

Fourier Simplifies Hydrogen Production

Recognizing the rapidly growing global energy demand, Fourier has developed a system that enables on-site and on-demand hydrogen production. In this new era, the need for more reliable, cost-effective, scalable, and sustainable energy solutions is greater than ever. Hydrogen, with its high energy density and eco-friendly profile, has significant potential to meet this demand. However, high costs, inefficient production methods, and complex logistics have long hindered the widespread adoption of hydrogen.

At the heart of Fourier’s technology lies an ultra-modular, software-defined system architecture that sets it apart from existing hydrogen solutions. This architecture is managed by advanced algorithms that not only operate the system but also monitor and predict performance in real time, minimizing downtime and maximizing operational efficiency.

The modular system can be easily configured and scaled to meet the specific needs of each site or application—whether to power a fleet of hydrogen vehicles or support industrial operations. This approach reduces upfront capital costs, simplifies installation, and enables scalability as demand grows. By overcoming the logistical limitations of traditional hydrogen production, Fourier paves the way for hydrogen to become a practical and cost-effective solution for transportation, heating and cooling, and energy storage.

Fourier’s founder and CEO, Siva Yellamraju—an experienced entrepreneur who previously sold ventures to companies like Apple and Google—states that he now aims to leverage his background to seize opportunities in the energy sector.

Defne Kocabıyık Narter: “We are thrilled to support Fourier.”

Commenting on the new investment, Borusan Ventures Founder and Chairperson Defne Kocabıyık Narter said:
“Fourier initially targets the transportation hydrogen market, which is challenged by high logistics costs and complex infrastructure. With its modular and on-site production model, it tackles these issues directly, enabling production even at very small scales and where it’s needed most—instantly creating value for customers. Our investment in Fourier’s innovative hydrogen production technology is a concrete example of Borusan Ventures’ vision to contribute to a sustainable future and support clean energy solutions. We’re excited to be part of Fourier’s journey to accelerate the widespread adoption of hydrogen.”
