Manufacturing Accelerator Re:Build, Former Parent of EV Startup Slate Auto, Secures $2.1B in Funding

Massachusetts-based manufacturing accelerator Re:Build has announced a $2.1 billion funding round to expand its domestic production capacity and launch new industrial startups. The company, which previously spun out electric vehicle startup Slate Auto in 2023, stated the capital will be used to scale the manufacturing of hard technology products within the United States.

Funding and Leadership Background

The investment round was co-led by General Catalyst and JPMorganChase’s Strategic Investment Group, while other participating investors were not publicly disclosed. Founded in 2020 by former Amazon commercial CEO Jeff Wilke and Miles Arnone, Re:Build counts several former Amazon executives among its leadership team, including Chief Digital and Product Officer Wei Gao.

Re:Build operates by partnering with industrial enterprises to design, engineer, and manufacture products at scale across sectors like aerospace and defense, alongside incubating new startups in underserved markets. The company reports that its network currently employs more than 2,100 people across the United States and encompasses over 2.4 million square feet of manufacturing capacity.

Connection to Slate Auto

In 2022, Wilke and Arnone conceived Slate Auto, later spinning it out in 2023 to secure independent capital. Since the spinout, Slate Auto has raised at least $1.4 billion—including investments from Jeff Bezos’ family office—as it pursues the development of an ultra-low-cost, customizable pickup truck.

Practical Implications and What Remains Unknown

For industry observers and automotive stakeholders, the massive influx of capital underscores a broader trend of redirecting investment toward domestic supply chains and hardware manufacturing as a hedge against overseas dependencies, particularly concerning China.

However, several details regarding the funding remain undisclosed:

• Confirmed Facts: Re:Build raised $2.1 billion led by General Catalyst and JPMorganChase’s Strategic Investment Group; the funds are designated for expanding domestic hard-tech manufacturing and industrial startups; the company previously spun out Slate Auto in 2023.
• Unknowns: The complete list of participating investors outside of the two leads was not revealed, and specific production timelines for the new industrial startups or the exact allocation of the $2.1 billion remain unannounced.
