(Hamburg, Germany) has raised €4.3 million to build its first autonomous production site for lightweight composite components in Hamburg. The new facility, scheduled to open later in 2025, combines robotics, AI and closed-loop recycling to scale composite part production with greater speed, cost efficiency and sustainability.

Composites manufacturing has traditionally been constrained by high costs, slow cycle times and limited scalability. While automation has reduced some manual work, most processes remain labor-intensive. Holy Technologies is addressing this by developing a fully autonomous production system designed from the ground up to eliminate trade-offs between cost, speed, performance and circularity.

Central to Holy Technologies’ system is its infinite fiber placement (IFP) technology. IFP places a continuous carbon fiber along a pre-calculated path, tailoring local properties — such as strength and stiffness — according to a part's performance requirements. It enables precise fiber deposition in complex geometries, combining robotics with digital control to optimize performance and material efficiency. The system comes with integrated closed-loop recycling. This means that components can be fully recovered at end of life and reused in equivalent applications, avoiding downcycling. While currently specialized in carbon fiber, the technology is designed to be material-agnostic.

Since its founding in 2022, Holy Technologies has:

• Built a fully operational pilot line
• Partnered with OEMs and Tier 1 suppliers in sectors including automotive, motorsports, aerospace, orthopedics and industrial tooling
• Secured its first serial production contracts, covering thousands of parts.

In a recent collaboration with a Formula 1 team, the company demonstrated a 20% weight reduction compared to incumbent composite parts, underscoring the performance potential of its technology.

The company’s most recent funding backed by Rockstart, Vanagon, Sands, Innovationsstarter Fonds Hamburg and EIT Manufacturing, alongside angel investors such as Adrian Locher (Merantix AG), Matthias Dantone (Ellipsis Ventures), Christian Vollmann (C1), Markus Kerkhoff (Poppe+Potthoff), Kai Müller (PowerCo) and Timm Moll (Moll Gruppe).

“Autonomy in composites is not just about efficiency,” notes Moritz Reiners, CTO and co-founder. “It enables entirely new component categories — lighter, stronger and recyclable. But to achieve this, you need to redesign the production system itself. That is exactly what we are doing.”
