Vibeflow secures $500K pre-seed funding for full-stack app platform

San Francisco-based AI startup Vibeflow has raised $500,000 in pre-seed funding from Y Combinator as part of the accelerator's Summer 2025 cohort, as the company develops its platform enabling non-coders to build full-stack web applications using natural language prompts and visual workflows.

Co-founded by Alessia Paccagnella and Elia Saquand, Vibeflow addresses the technical barriers preventing non-developers from creating web applications by combining AI-powered code generation with visual backend editing. Users describe their app concept in plain language, and the platform automatically generates database schemas, API endpoints, and business logic that can be refined through drag-and-drop workflows.

The platform integrates with GitHub for version control and deployment, allowing users to connect custom frontends while visually creating backend logic for authentication, payments, AI features, and enterprise workflows. Central to their approach is visual debugging in which their interface displays backend logic as flowcharts, enabling real-time troubleshooting without traditional coding knowledge.

Target applications include SaaS development, enterprise workflow automation for sales, HR, finance, and customer support, as well as rapid prototyping for business logic validation. The platform focuses on web applications rather than mobile development, aiming to democratise full-stack development for business users.

The funding will support product development and team expansion as Vibeflow scales its AI-powered no-code platform for the growing market of citizen developers and business users seeking to build custom applications.
