Re:Build Manufacturing helps industrial companies, inventors, and startups turn physical products from early concepts into engineered, validated, and scaled production. Its work spans product design, engineering, automation, components, batteries, medical manufacturing, robotics, and factory systems.

  • New funding: $2.1 billion announced on October 27, 2026, led by General Catalyst and JPMorganChase's Strategic Investment Group; TechCrunch reported the financing without a disclosed valuation or round name.techcrunch.comrebuildmanufacturing.com
  • Product output: TechCrunch reports that Re:Build has launched hundreds of products and production systems during its six-year existence.techcrunch.com
  • Business mix: Aerospace and defense account for approximately 40% of Re:Build's business, according to CEO Miles Arnone's interview with Tectonic Defense.tectonicdefense.com

WHY WE WOULD WORK AT RE:BUILD MANUFACTURING

Rebuild American Industry

Help make the next generation of important products at scale in America. Re:Build is strengthening domestic production across aerospace, defense, electrification, medical, energy, and robotics.

Work End to End

Take physical products from concept through engineering, prototyping, validation, and scaled production. You can see your work move from "Brain to Box" rather than stopping at a single development stage.

Solve Hard Tech

Work across robotics, industrial automation, embedded controls, composites, precision metals, batteries, and electrification systems. Projects include UAVs, battery packs, medical products, factory equipment, and aerospace components.

Build With Momentum

A $2.1 billion financing is funding new manufacturing capacity, acquisitions, and industrial-company spinouts. The platform has grown to more than 2,100 U.S. employees, 2.4 million square feet, and 13 acquired businesses.

Learn Across Specialists

Collaborate with engineers, designers, automation experts, and manufacturing teams across a network of specialized operating companies. Re:Build emphasizes knowledge sharing, constructive dissent, accountability, and continuous improvement.

Launch What Matters

Help turn ambitious ideas into production-ready products, including work for Boeing, Airbus, Bell, Sikorsky, Stryker, Form Energy, and other industrial innovators. The company has launched more than 800 specialized products and production systems.

MARKET AND TRACTION

GROWTH TACTICS

  • Expands through long-term industrial partnerships, strategic acquisitions, and incubation of new industrial companies.

  • Uses its integrated platform of engineering, manufacturing capacity, capital, and operational support to help physical-product companies move from concept to scaled production.

  • The company has incubated ventures including Slate, Neon Aero, and Ensorcell.

    • NOTABLE CUSTOMERS

  • Re:Build's highlighted customers include 3M, Airbus, Boeing, Bell, GE, Sikorsky, Stryker, Whirlpool, Virgin Galactic, Form Energy, Ginkgo Bioworks, and Antora Energy.

  • The company does not publicly disclose contract sizes, customer counts, or the exact services delivered for each highlighted customer.

    • KEY METRICS

    ✦ KEY METRIC
  • Re:Build reported more than 2,100 U.S. employees and over 2.4 million square feet of advanced manufacturing capacity as of October 2026.

  • The company cites more than 450 engineers, over 800 specialized products launched, more than 14 U.S. locations, and approximately 13 acquired manufacturing and engineering businesses.

  • Re:Build announced $2.1 billion in new funding in October 2026, following a disclosed $120 million General Catalyst investment in 2024.

    • COMPETITIVE ADVANTAGE

  • Re:Build integrates product and industrial design, engineering, prototyping, automation, component manufacturing, and scaled production within a single U.S.-focused platform.

  • Its Manufacturing Constrained Design and "Brain to Box" approaches involve manufacturing engineers early, incorporating cost, tooling, capacity, quality, and production requirements into product development.

  • Long-term ownership, specialized operating companies, and domestic manufacturing capacity differentiate the company from conventional contract manufacturers and standalone engineering firms.

    • MARKET POSITION

    ✦ KEY METRIC
  • Re:Build serves aerospace and defense, electrification, energy and environment, medical, and robotics and automation markets, with additional activity across industrial equipment, mobility, cleantech, life sciences, and energy storage.

  • The company positions itself as an integrated U.S. advanced-manufacturing platform focused on helping important physical products reach production at scale in America.

  • Aerospace and defense reportedly account for approximately 40% of the business, according to a 2026 interview with CEO Miles Arnone.

    • PRODUCT AND TECH

    Product Engineering

    Provides industrial and product design, mechanical and electrical engineering, prototyping, testing, and product validation from concept through production.

    Manufacturing-Constrained Design

    Its Manufacturing Constrained Design and Brain to Box methodologies bring manufacturing engineers into development early, aligning products with cost, tooling, capacity, quality, and production requirements.

    Advanced Component Manufacturing
