Re:Build, the Incubator Behind Slate Auto, Lands $2.1 Billion

Re:Build, the Massachusetts industrial accelerator that gave birth to EV startup Slate Auto, has closed a $2.1 billion funding round. The money comes from General Catalyst and JPMorganChase’s Strategic Investment Group, with other backers kept under wraps.

The stated goal is expansion — more capacity to manufacture hard tech products at scale, and more new industrial startups spun out of its ecosystem. It’s a big bet on the idea that the next generation of innovative hardware can be built on American soil.

Amazon DNA Runs Deep

Re:Build started in 2020 and markets itself, bluntly, as “America’s answer to Shenzhen.” Its leadership reads like a slice of Amazon’s old guard: co-founder Jeff Wilke spent years as Amazon’s commercial CEO, while chief digital and product officer Wei Gao was a longtime VP and technical adviser to Jeff Bezos. Several other executives also came over from the e-commerce giant.

Wilke has framed the whole project in stark terms. He said Re:Build exists because “the deindustrialization of America is an economic failure and national security risk,” and that this capital lets the company move faster than it otherwise could.

What Re:Build Actually Does

The company operates on two tracks:

• Contract manufacturing: partnering with industrial firms to design, engineer and build products at scale, including in aerospace and defense
• Incubation: launching startups in what it calls critical, underserved markets

By its own count, Re:Build has rolled out hundreds of products and production systems since 2020. Its network employs over 2,100 people in the U.S. and holds more than 2.4 million square feet of manufacturing space.

Slate Auto Is the Headline Spinoff

The company Wilke and co-founder Miles Arnone sketched out in 2022 has since become the most visible piece of the Re:Build story. Slate Auto was deliberately spun out to chase outside capital, and it has now brought in at least $1.4 billion on its own, including money from Bezos’ family office.

Slate’s pitch is unusual in today’s EV market: a stripped-down, ultra-low-cost pickup buyers can customize themselves. No giant touchscreen arms race, no luxury trim ladder. Just a simple, affordable truck.

General Catalyst CEO Hemant Taneja tied the funding to a wider shift. Competing with China, he argued, means rebuilding American industrial capacity — and that requires companies operating at real scale, plus an innovation ecosystem that remembers how to make hardware. For a sector that has spent a decade chasing software margins, that’s a pointed message.

Re:Build hasn’t said exactly where the new money will land first. But the direction is clear: more factories, more spinoffs, more hardware stamped “made in America.”
