About
Lovable was founded in 2023 and built a full-stack AI application builder that lets non-technical users create production-ready web applications through natural language conversation. The platform, originally launched as GPT Engineer, enables users to describe what they want to build and iteratively refine it through chat—with Lovable generating, deploying, and hosting a real full-stack application including frontend, backend logic, and database integration. Its target users are entrepreneurs, product managers, designers, and business professionals who want to build software products without writing code.\n\nLovable's platform handles the entire application lifecycle: from initial generation through Supabase-backed database setup, authentication, deployment, and ongoing iteration. Users can connect custom domains, integrate with third-party APIs, and collaborate with team members—all without touching code directly, though developers can also access the underlying codebase for advanced customization. The "vibe coding" paradigm Lovable helped define has proven to be a genuine product category, not just a demo, as evidenced by a growing cohort of businesses running real products built entirely on the platform.\n\nLovable achieved $100M in ARR faster than any software company in history—reaching that milestone in approximately 8 months—and surpassed $200M ARR by Q1 2026. The company raised a $330M Series B at a $6.6B valuation, reflecting investor conviction in the durability of AI-native application development as a massive market. This traction puts Lovable alongside Cursor and Windsurf as defining companies of the vibe coding era, though Lovable's non-technical user focus gives it a distinct and potentially larger total addressable market.
