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

Borusan Ventures, the corporate venture capital arm of the Borusan Group, continues to invest in technologies that enable energy generation from sustainable sources. Fourier, a company developing modular electrolyzer systems for hydrogen production, has raised $18.5 million in a Series A funding round that included participation from Borusan Ventures.

Borusan Ventures, in line with its vision to support innovation in its key focus areas, joined the Series A round for Fourier, a U.S.-based startup that develops modular electrolyzers for on-site hydrogen production. The round was led by General Catalyst and Paramark Ventures, with participation from Airbus Ventures, MCJ, GSBackers, and Positive Ventures.

Headquartered in Silicon Valley, Borusan Ventures invests in early-stage startups across the U.S. and Europe in sectors such as energy, mobility, logistics, supply chain, and industrial technologies. Leveraging Borusan Group’s 80+ years of industrial expertise, Borusan Ventures provides strategic support to startups aiming for global success and long-term impact, offering access to new markets and growth opportunities.

Fourier Simplifies Hydrogen Production

Driven by the rapidly increasing global energy demand, Fourier has developed a system that enables on-site and on-demand hydrogen production. As the world moves toward more reliable, cost-effective, scalable, and sustainable energy solutions, hydrogen stands out for its high energy density and environmentally friendly characteristics. However, for decades, widespread adoption of hydrogen has been limited by high costs, inefficient production methods, and complex logistics.

At the core of Fourier’s technology lies an ultra-modular, software-defined system architecture that sets its hydrogen production apart from existing solutions. Managed by advanced algorithms that optimize performance in real time, this architecture not only operates the system but also monitors and predicts performance to minimize downtime and ensure maximum operational efficiency.

The modular system can be easily configured and scaled to meet the specific needs of any site or application—whether powering a hydrogen vehicle fleet or supplying energy to industrial operations. This approach reduces initial investment costs, simplifies installation, and enables scalability as demand grows. By eliminating the logistical barriers of traditional hydrogen production, Fourier makes hydrogen a viable and cost-effective solution for sectors such as transportation, heating and cooling, and energy storage.

Fourier’s founder and CEO, Siva Yellamraju, is an experienced entrepreneur who previously sold his ventures to companies like Apple and Google. He now aims to leverage his expertise to capture opportunities within the energy sector.

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

Defne Kocabıyık Narter, Founder and Chairwoman of Borusan Ventures, shared her thoughts on the investment:

“Fourier is initially targeting the transport hydrogen market, which has traditionally been burdened by high logistics costs and complex infrastructure. By enabling modular and on-site production, it allows customers to generate hydrogen exactly where they need it, at low cost and even on a very small scale—creating immediate value. Our investment in Fourier’s innovative hydrogen production technology is a tangible reflection of Borusan Ventures’ commitment to contributing to a sustainable future and supporting clean energy solutions. We are truly excited to be part of Fourier’s journey to accelerate the adoption of hydrogen.”
