Layup Parts, a startup aiming to revolutionize the composite materials supply chain, has successfully closed a $42 million Series A funding round. The investment was led by dual-use venture fund Marlinspike, with significant participation from new and existing partners, including Cerberus Ventures and Founders Fund. This capital infusion will accelerate the company's mission to make sourcing custom carbon fiber and fiberglass components as simple as an online purchase.


A Vision Forged in Defense and Technology

Founder Zack Eakin brings a wealth of experience from high-performance engineering sectors, including motorsports with Chip Ganassi Racing and as the first engineer at Elon Musk's The Boring Company. His most recent role at defense technology firm Anduril proved pivotal, where he refined his business concept with guidance from co-founders Palmer Luckey, Brian Schimpf, and Matt Grimm. This mentorship provided a crucial foundation for his entrepreneurial journey.

While at Anduril, Eakin identified a critical gap in the advanced manufacturing landscape that was holding back innovation. He observed that while sectors like metal fabrication were being transformed by rapid prototyping services, the composites industry remained slow and complex. This bottleneck was caused by a lack of software integration and industry consolidation, which stifled progress and created significant delays for companies needing specialized parts.

Recognizing the widespread nature of this supply chain issue, Eakin concluded that the most effective solution was to build a new company from the ground up. He viewed this as a way to not only support Anduril's needs but also to serve the broader aerospace, defense, and automotive industries. This strategic decision led to the founding of Layup Parts, a venture designed to modernize a traditionally challenging manufacturing vertical.

Streamlining Composite Manufacturing

Layup Parts is fundamentally changing how custom components are produced by integrating sophisticated software to automate the engineering process. The company's goal is to create a seamless, near-zero-click experience, taking customer data and rapidly generating manufacturing instructions for complex parts. This approach has already dramatically reduced production timelines, cutting down processes that once took weeks to mere hours in some instances.

In just two years since its inception, the Huntington Beach-based startup has attracted a diverse clientele, producing components for motorsports teams, automotive design studios, and even pickleball paddle manufacturers. However, its primary focus remains on the demanding aerospace and defense sectors, where it serves both agile startups and established prime contractors. This broad market appeal demonstrates the universal need for faster and more reliable composite manufacturing solutions.

The successful $42 million Series A round underscores strong investor confidence in the company's vision and execution. Led by Marlinspike, the round also welcomed new investors Cerberus Ventures and Pinegrove Venture Partners. Continued support from existing backers like Founders Fund and Lux Capital further validates the company's progress since its initial $9 million seed round two years ago.

Fueling Future Growth and Expansion

With the new capital, Layup Parts plans to significantly scale its operations and team of around 60 employees. While the initial seed funding was primarily allocated to capital expenditures, this Series A round will fuel recruitment and facilitate a move into a larger production facility this year. This expansion is critical to meeting growing customer demand and advancing the company's technological capabilities.

Eakin's leadership style is heavily influenced by his time at The Boring Company, where he embraced a culture of high urgency and first-principles engineering. This fast-paced, problem-solving mindset is now embedded in Layup Parts' DNA, driving the team to develop innovative solutions under demanding deadlines. It is this combination of technical expertise and agile execution that positions the company for continued success.


This latest funding round marks a significant milestone for Layup Parts, positioning it to become a leader in the advanced manufacturing sector. By tackling the long-standing complexities of composite production, the company is not just building a successful business but also unlocking new potential for innovation across critical industries. As Layup Parts expands its team and capacity, it is set to redefine the standards for speed, cost, and consistency in the global supply chain.
