Builds an AI-powered platform that uses computer vision to automatically generate manufacturing-ready 2D engineering drawings from 3D CAD models, targeting mechanical engineering teams at hardware companies.
REV1 has publicly positioned itself as "Claude Code for Mechanical Engineers," focusing on automating the creation of standards-compliant 2D drawings (ASME, GD&T) from 3D CAD files. The GD&T tolerancing standard alone is over 300 pages of rules. Start with a 3D CAD file, specify your design intent, and REV1 generates a fully annotated drawing with proper GD&T. Their Launch YC page highlights PLM synchronization, design intent communication in 3D, and a native review/editing interface.
GitHub and hiring signals are minimal, suggesting deep stealth-mode product development. The presence of a dedicated computer vision engineer (Aleksa Filic) alongside the ML co-founder (Louis Liu) hints at proprietary vision models for CAD feature extraction beyond pure LLM prompting. The combination of Tesla/Apple hardware pedigree with academic AI research suggests potential partnerships or pilot programs with major hardware OEMs.
Automated generation of manufacturing-ready 2D engineering drawings with GD&T annotations from 3D CAD models using Claude LLMs and computer vision.
An AI looks at your 3D part design and automatically creates the precise, annotated flat blueprints that factories need to build it—a task that used to take engineers hours of tedious manual work.
It's like having a brilliant junior engineer who memorized every page of the ASME standards handbook and can draft perfect blueprints in minutes instead of hours—except they never call in sick.
AI-powered capture and communication of design intent from 3D models to manufacturing partners, ensuring critical features and requirements are unambiguously conveyed.
The AI reads your 3D design and automatically figures out which surfaces and features are most critical, then writes clear manufacturing instructions so the factory builds exactly what you intended.
It's like a translator who not only speaks both "engineer" and "machinist" fluently but also knows from experience exactly which instructions get lost in translation and preemptively clarifies them.
AI-driven synchronization of engineering drawings and documentation across PLM systems, automatically updating downstream artifacts when 3D models change.
When an engineer changes a 3D design, the AI automatically updates all the related blueprints and factory documents everywhere they live—so nothing is ever out of date.
It's like having a hyper-organized assistant who, every time you rearrange furniture in one room, instantly updates the floor plans, the insurance documents, and the moving inventory—without you ever asking.
Alex Rivero is a former mechanical engineer at Apple and Tesla, giving him firsthand experience with the exact drawing creation pain point REV1 solves. Louis Liu brings ML research expertise from the University of Toronto. Together they combine deep engineering domain knowledge with frontier ML techniques needed to automate manufacturing drawings — a combination almost no competitor possesses.
