Ex-Anduril Engineer Raises $42M to Build Marketplace for Composite Parts

Layup Parts, a California-based composites manufacturing startup, has raised $42 million in Series A funding led by Founders Fund, the company's second funding round in just over two years. The Huntington Beach-based company was founded by former Anduril engineer Zack Eakin alongside co-founders Brian Schimpf and Matt Grimm in January 2024.

Eakin, who has worked with composite materials for approximately two decades, left Anduril in 2024 specifically to launch Layup Parts. The startup positions itself as building an "Amazon for composite parts," targeting the fragmented market for carbon fiber and other advanced composite manufacturing.

Rapid Funding Trajectory

The Series A follows an earlier $9 million round, also led by Founders Fund, which closed just five months after the company's founding. This puts Layup Parts on an accelerated funding timeline that reflects both investor confidence in the composites market opportunity and the team's industry credentials.

The broader context here reveals an interesting pattern in defense-adjacent manufacturing startups. Founders Fund's consecutive investment rounds suggest the firm sees significant scalability potential in digitizing what has traditionally been a highly manual, relationship-driven supply chain. Composite parts manufacturing has long operated through networks of specialized shops and direct relationships between aerospace primes and their suppliers.

Defense Industry Origins

Eakin's background at Anduril, Palmer Luckey's defense technology company, provided direct exposure to the procurement challenges that Layup Parts now aims to solve. According to sources, Luckey himself allowed Eakin to workshop the initial pitch for Layup Parts, indicating support from the Anduril leadership team for the venture.

This connection matters because Anduril has been pushing to streamline defense manufacturing through software-driven approaches and standardized component libraries. The company's experience with rapid prototyping and production scaling in defense contexts likely informed Eakin's understanding of where bottlenecks persist in composite part sourcing.

Market Dynamics in Composites

The composites manufacturing sector has historically operated as a collection of specialized job shops, many serving aerospace and defense customers with highly customized parts and lengthy qualification processes. Carbon fiber components, in particular, require precision layup processes and curing cycles that have limited automation potential compared to traditional machining.

Layup Parts enters this market at a time when both commercial aerospace and defense sectors are pushing for faster development cycles and more agile supply chains. SpaceX's manufacturing approaches have demonstrated that rapid iteration is possible even with advanced materials, while defense contractors face increasing pressure to reduce program timelines.

Looking at what this means for the broader manufacturing ecosystem, a successful marketplace model could significantly reduce lead times for prototype and low-volume production parts. The challenge will be balancing the quality assurance requirements that aerospace and defense customers demand with the speed and accessibility that a digital marketplace promises.

Historical Precedent

We have seen this pattern before, when companies like Proto Labs and Xometry digitized machining and injection molding services in the 2000s and 2010s. Those platforms succeeded by abstracting away the complexity of finding and qualifying machine shops while maintaining quality standards through vetted supplier networks. However, composites manufacturing involves more process variables and quality control requirements than traditional subtractive or additive manufacturing methods.

The key difference is that composite parts often require material certifications, process witness points, and environmental controls that make the manufacturing process less commoditizable than CNC machining. Layup Parts will need to solve not just the discovery and quoting problem, but also the traceability and quality assurance challenges that aerospace and defense customers require.

Technical Infrastructure Requirements

Building a viable marketplace for composite parts requires solving several technical challenges beyond typical B2B platform development. The startup will need to develop automated quoting algorithms that account for material specifications, layup schedules, cure cycles, and post-processing requirements. Unlike machining operations where geometry largely determines cost and feasibility, composite manufacturing involves complex interactions between part design, tooling requirements, and production volumes.

Quality control presents another layer of complexity. Composite parts are highly sensitive to environmental conditions during manufacturing, and defects may not be visible until destructive testing or field failure. Any marketplace model will need to address how quality standards are maintained across a distributed supplier network.

Defense Sector Implications

Eakin's Anduril background positions Layup Parts to understand defense procurement requirements, which could provide a competitive advantage in serving military and aerospace customers. Defense programs often require domestic manufacturing, specific material certifications, and supply chain transparency that commercial marketplaces typically do not address.

The timing aligns with broader Department of Defense initiatives to strengthen domestic manufacturing capabilities and reduce dependency on traditional defense primes for component-level sourcing. Programs like the Defense Production Act investments and the CHIPS Act manufacturing incentives have created funding streams for companies that can demonstrate secure, scalable domestic production capabilities.

In my view, the most interesting aspect of this funding round is how it positions Layup Parts to potentially reshape procurement practices across the defense industrial base. If the company can successfully standardize composite part sourcing while maintaining the quality and security requirements that defense customers demand, it could accelerate the broader trend toward software-enabled defense manufacturing that Anduril and companies like it have been driving.
