Fiber Global Raises $20M to Expand Sustainable Building Materials, Backed by DBL Partners

BROWNSBURG, Ind.—Fiber Global, a rising innovator in climate-conscious construction solutions, has announced a $20 million Series A funding round to accelerate its expansion in the U.S. market. The funding, led by DBL Partners, aims to bolster Fiber Global’s mission of converting global waste streams into durable, low-carbon building materials.

DBL Partners’ Founder and Managing Partner Ira Ehrenpreis has joined Fiber Global’s Board of Directors, reinforcing the firm’s hands-on support and belief in the company’s long-term impact.

“From day one, our relationship with DBL Partners and Ira Ehrenpreis has been invaluable,” said KC McCreery, Founder and CEO of Fiber Global. “Their team brings more than just investment; they actively engage and support our growth on a daily basis with intentionality. DBL Partners and Ira Ehrenpreis are truly part of the Fiber Global team, sharing our mission and vision of reclaiming tomorrow. This investment round provides us with the ability to continue rapidly scaling our United States manufacturing footprint and production capacity."

Fiber Global has developed a proprietary platform that transforms readily available waste into building products that rival traditional materials in strength and reliability, while drastically reducing carbon emissions. All of its products are formaldehyde-free, have zero VOCs, and carry the UL GREENGUARD GOLD certification.

With the construction sector responsible for more than 10% of global greenhouse gas emissions, Fiber Global’s approach to circular manufacturing offers a powerful alternative. The company’s strategy also supports domestic manufacturing and job creation, aligning with broader efforts to localize supply chains and reduce environmental impact.

“Fiber Global exemplifies the mission-driven, execution-oriented companies DBL seeks to back,” said Ehrenpreis. “KC and his team are building a platform with the potential to revolutionize the building materials sector, combining sustainability, performance, and affordability at scale. Fiber Global is building a better and more economically compelling product that also has a superior environmental footprint, demonstrating how double bottom line is not about tradeoff or compromise but about winning with the best value proposition.”

Over the last two and a half years, Fiber Global has concentrated on validating and scaling its technology, partnering with established players in the materials sector to integrate its low-carbon products across various applications. The Series A round is a milestone in the company’s growth, confirming both market demand and investor confidence in its solution.

As governments, builders, and developers increasingly prioritize climate resilience and supply chain diversification, Fiber Global is positioned to serve as a key enabler of sustainable construction.
