From Anduril to Amazon of Composites: Zack Eakin's $42M Startup Layup Parts! (2026)

In the ever-evolving world of startups and innovation, a fascinating story unfolds with the rise of Layup Parts, a company aiming to revolutionize the composite parts industry. This article delves into the journey of Zack Eakin, a former engineer with a unique background, and his ambitious vision to create an 'Amazon' for custom composite materials.

The Birth of an Idea

Zack Eakin's path to entrepreneurship is an intriguing one. After gaining experience in motorsports and working with carbon fiber structures, he took a detour to become the first engineer at Elon Musk's The Boring Company. This diverse background, coupled with his time at Anduril, a defense startup, provided him with a unique perspective on the composite parts industry.

A Revolution in the Making

During his time at Anduril, Eakin witnessed a revolution in industrial fabrication and manufacturing. Startups were streamlining the prototyping and shipping of parts, but composites remained a challenge. This realization sparked an idea: why not make ordering custom composite parts as seamless as shopping on Amazon?

The Pitch and the Mentors

Eakin's journey began with a pitch to his former colleagues at Anduril. Each co-founder provided valuable feedback: from refining the VC pitch to strategizing and storytelling. This miniature boot camp, guided by experienced mentors, laid the foundation for his successful startup venture.

Funding and Growth

Layup Parts has secured impressive funding, with a $42 million Series A round led by Marlinspike, a dual-use venture fund. The startup's vision and potential have attracted notable investors, including Cerberus Ventures and Pinegrove Venture Partners. With just 60 employees, this funding will enable Layup Parts to expand its team and move into a larger facility, a testament to the company's rapid growth.

The Composite Challenge

Composites present unique challenges due to their complex nature and the involvement of multiple processes. Eakin recognized that the industry lacked innovation, with bigger firms hesitant to disrupt their revenue streams. He saw an opportunity to streamline the process, reduce the 'clicking' required for part production, and ultimately aim for a zero-click solution.

Rapid Prototyping and Customer Focus

In just two years, Layup Parts has made significant strides. The team has rapidly prototyped and produced parts for various customers, reducing manufacturing time from weeks to hours. This customer-centric approach has attracted a diverse range of clients, from motorsports to design studios and even pickleball paddle companies.

Defense and Aerospace Opportunities

The biggest business lines for Layup Parts are unsurprisingly in aerospace and defense. Eakin's background in these industries, coupled with his innovative approach, has positioned the company well to serve both startups and traditional defense primes.

Investor Confidence

The cap table speaks volumes about the potential of Layup Parts. Investors with defense and manufacturing expertise, such as Marlinspike and Cerberus Ventures, have backed the company. This confidence from industry insiders is a strong indicator of the startup's future success.

Lessons from The Boring Company

Eakin's experience at The Boring Company, despite not directly involving composites, taught him valuable lessons in 'first-principles engineering.' The high-pressure environment and tight deadlines at Elon Musk's company prepared him for the challenges of a startup, a skill he carries over to Layup Parts.

Conclusion

Zack Eakin's story is a testament to the power of diverse experiences and innovative thinking. Layup Parts has the potential to disrupt the composite parts industry, making it more accessible and efficient. With a strong team, investor support, and a customer-centric approach, the startup is well-positioned to make its mark. As Eakin puts it, 'the best way to do this was to start a whole new composites company,' and his vision is rapidly becoming a reality.
