Design used to be about rectangles on a canvas. Development was code in an IDE. The gap between them? Endless handoffs, mismatches, and wasted cycles. Were here to change that. We’re building an AI-native, code-based design tool that lets designers vibe design directly on real UI components - with an AI-native design engineer, on a canvas that thinks in code. With Jux, designers can: –Import and evolve Figma assets –Design with tokens, systems, and real code –Preview and publish live components –Collaborate with developers in a common language The result: UI that’s immediately production-ready. This is more than speeding up design. It’s a new foundation for product development - where AI helps automate the repetitive. Our belief is simple: Designers should focus on creation. Devs should receive real, working components. And AI should assist in between. Are you Juxed?

Stealth AI Startup is an independent initiative focused on founders building AI companies before public launch. We explore the earliest stages of building an AI startup—from testing an idea and finding collaborators to assembling a team and preparing to launch. Our focus: • Founder experiences and lessons from building in stealth • Emerging AI technologies and startup trends • Perspectives from founders, researchers, engineers and investors • Practical learning for the journey from idea to launch We believe founders can exchange knowledge and build meaningful professional connections while keeping their products and plans confidential. This is the official LinkedIn Page of the Stealth AI Startup initiative. It represents our initiative, rather than the separate companies built by founders who follow it. Following or engaging with this page does not, by itself, establish employment, partnership or endorsement. Follow us for perspectives on building AI companies and updates from our initiative.
