In the race to build lighter, stronger and more sustainable components, composite materials, such as carbon fiber, have become key players. But conventional methods for producing them remain costly, manual and hard to scale. Hamburg-based company Holy Technologies is tackling this challenge head-on, by making the production process faster, scalable, cost-efficient and circular by design.
The company recently raised EUR 4.3 million to build the first autonomous factory for composite components, advancing its mission to deliver “radically better lightweight components”. The round was joined by EIT Manufacturing, Rockstart, Vanagon, SANDS, Innovations starter Fonds Hamburg and notable angel investors, drawn by Holy’s blend of automation, sustainability and circular design.
Founded in 2022 by Bosse Rothe Frossard and Moritz Reiners, Holy Technologies combines deep industrial expertise in aerospace and automotive with PhD-level know-how in robotics and composite engineering.
Their goal is bold: to make composite manufacturing autonomous, helping manufacturers build products that are lighter, longer-lasting and more sustainable.
An end-to-end solution for composite manufacturing
Holy Technologies’ technology focuses on automating the entire product lifecycle of composite parts: from design to prototyping, mass production and ultimately, recycling.
Their patented robotic system “Infinite Fiber Placement” (IFP) places a continuous carbon fibre along a pre-calculated path, optimising strength, stiffness and flexibility exactly where needed. This approach removes the inefficiencies of traditional processes and allows components to be designed for performance and recyclability from the start.
Crucially, their system is not only automated but also designed with circularity in mind. By tracking fibre placement and using a recyclable resin system, Holy Technologies enables recovery of composite fibres at the end of a product’s life. Tests show that fibres can be reused multiple times with an average retention of 97% of their original mechanical performance.
Autonomous manufacturing is not just about efficiency: it enables a new category of components that outperform on weight, performance and sustainability. But the path to autonomy is complex. It requires systems built from scratch to deliver it. That is exactly what we are building.

From prototyping to scaled production
Since its founding, Holy Technologies has built a fully operational pilot line, partnered with OEMs and Tier 1 suppliers across automotive, motorsports, aerospace, industrial tools and orthopedics, and secured its first serial production contracts for thousands of parts. Their product innovation service helps manufacturers design and prototype new components, before moving into serial production. With the launch of their new factory, they are taking the next step: proving they can mass-produce composite parts with consistent quality and speed.
European roots, global potential
As part of EIT Manufacturing’s Investment Programmes, Holy Technologies has benefitted not only from financial backing but also strategic mentorship, European visibility and access to a growing network of industry contacts.
EIT Manufacturing has been instrumental in opening doors to media, events and key industry players, while providing valuable strategic mentorship. Their support goes far beyond funding and helps us accelerate our path from prototypes to large-series production.

With its team, Holy Technologies is now scaling both its operations and its vision. A new facility is on the horizon, aimed at accelerating the move from small-batch prototypes to large-series production.
Redefining what’s possible with composites
Holy Technologies represents a new kind of manufacturing startup: one that blends deep-tech innovation with real industrial application, all while staying rooted in sustainability. As Europe’s manufacturing sector pushes toward smarter, greener practices, solutions like theirs will be vital in making materials work harder, last longer and cycle more sustainably through the economy.
