Layup Parts Secures $42M to Modernize Composite Manufacturing

Layup Parts, a startup founded by former Anduril engineer Zack Eakin, has secured $42 million in Series A funding to streamline the production of custom composite components. Led by Marlinspike, with participation from Founders Fund and Lux Capital, the investment follows a successful $9 million seed round. The company plans to utilize this capital to expand its workforce and scale its manufacturing facilities in Huntington Beach, California.

The core mission of Layup Parts is to transform the traditionally labor-intensive composite manufacturing sector into a streamlined, digital-first experience. Drawing inspiration from platforms like SendCutSend and Protolabs, Eakin aims to create an "Amazon-like" ordering process for carbon fiber and fiberglass parts. By developing proprietary software that automates design and production workflows, the company seeks to reduce the manual oversight—or "fingers and eyeballs"—that has historically hindered efficiency in the industry.

This initiative addresses a significant bottleneck in modern industrial fabrication. While other manufacturing verticals have benefited from rapid prototyping advancements, the composites market has remained fragmented and resistant to innovation due to consolidation and a lack of specialized software talent. By focusing on software-driven manufacturing, Layup Parts intends to provide a scalable solution for high-tech sectors, including defense and aerospace, that currently struggle with slow, unreliable supply chains.

Ultimately, Layup Parts represents a strategic effort to modernize critical infrastructure. By moving toward a "zero-click" production model, where customer data is automatically translated into finished shapes, the company is positioning itself to solve a systemic supply chain issue. If successful, Layup Parts could become a vital utility for hardware-focused companies, significantly reducing the time and cost barriers associated with advanced material engineering.
