ion design is a San Francisco AI company (YC W24) building tools that let non-engineers ship real UI changes to a live codebase. It started by turning Figma designs into clean React code, grew into a Figma-like visual editor that opens branches and pull requests against your GitHub, and now runs autonomous AI product-design agents that create and test on-brand pages to grow revenue. Founded in 2023 by Samraaj Bath, it targets the gap between people who can ship code and the PMs, designers, and marketers who cannot.
Tempo is a Toronto-based, Y Combinator-backed (S23) AI development environment for React. It pairs a drag-and-drop visual editor with AI code and reasoning agents so founders, product managers, designers, and engineers can build and ship production-grade React apps from the same canvas. Optimized for Vite and Tailwind, it works on real production codebases rather than throwaway prototypes, and connects to backends like Supabase and payment tools like Stripe through its MCP App Store.
Replo is a San Francisco-based software company that lets ecommerce marketing teams design, launch, and test high-converting Shopify pages without writing code. Built around a visual drag-and-drop editor, hundreds of templates, live product-data integration, and increasingly AI-driven page generation, Replo targets mid-market direct-to-consumer brands that need custom landing pages and marketing funnels fast - without hiring engineers. Founded in 2021 by ex-Uber and PlanGrid engineers Yuxin Zhu and Noah Gilmore, the Y Combinator-backed startup has grown to thousands of ecommerce customers.
Webflow is a San Francisco-based SaaS platform that lets designers, marketers, and developers build production-ready websites without writing code - or with it, if they want. Founded in 2013 after three failed attempts and a near-bankruptcy, the company grew into a $4 billion business serving over 300,000 teams including The New York Times, TED, Dropbox, Dell, Discord, and Monday.com. Its visual editor outputs clean HTML, CSS, and JavaScript automatically, while its built-in CMS, hosting, ecommerce, and now AI-powered tools make it a full-stack web platform. In 2025 and 2026, Webflow pushed deeper into enterprise with a next-gen CMS, AI prompt-to-production site building, answer engine optimization (AEO), and the acquisitions of animation library GSAP and AI content platform Vidoso.ai.
