What Re:Build does

Re:Build Manufacturing is a U.S.-based advanced manufacturing services company founded in 2020 by former Amazon retail chief Jeff Wilke and investor Will Barker. The company operates as an integrated design-engineering-manufacturing platform serving startups and established enterprises across five primary verticals: aerospace & defense, electrification, energy & environment, medical, and robotics & automation. Re:Build is structured as a manufacturing holding company with 14+ U.S. facilities totaling nearly 1 million square feet of advanced manufacturing capacity, employing 1,200+ team members including 400+ engineers, and delivering programs from prototype through full-rate production.

Core technology centers on the proprietary Manufacturing Constrained Design (MCD) methodology, which embeds manufacturing engineers at the start of each program to align design innovation with production constraints from day one, eliminating design-to-production handoffs. Internal proprietary platforms include smartBuild (an AI-first digital wire harness assembly platform developed by subsidiary Cadonix), Arcadia ECAD (cloud-based wire harness design), and custom UAV optimization software used in the XRAE-1 program. The subsidiary portfolio also encompasses Ensorcell (Versaweld sterile tube welder with patented hot-ribbon and selector-wheel technologies), Re:Build Battery Solutions (domestic battery pack design, BMS, and system integration), and historically Slate Auto (incubated internally and spun off as an independent company in 2022). Other internally developed product lines include the Battery Cell Testing Automation system, SOFC Stack Assembly Automation, Modular BMS Platform, Stack Health Monitor, and Phase Maintenance Kits for military rotorcraft.

Revenue is generated primarily through B2B engineering and manufacturing services contracts spanning the full product lifecycle — design, prototyping, testing, automation, and volume manufacturing — on long-cycle program engagements. Ancillary revenue streams include product sales and licensing of the smartBuild platform to external wire harness manufacturers. Re:Build markets through direct enterprise sales, content marketing via case studies on its corporate website, and participation in industry conferences such as WHMA and The Battery Show. Customers range from two-person startups (e.g., Rovo Medical, an FDA 510(k)-cleared rotational thrombectomy developer) to major defense and aerospace primes and established OEMs, with named engagements including Enigma Aerospace, Alsym Energy, Foundation Alloy, a major defense contractor counter-UAS program, and a major helicopter OEM. The company is privately held and has raised $120 million from General Catalyst as sole investor in August 2024.
