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.
Directus is an open-source data platform that wraps any SQL database with an instant REST and GraphQL API plus a no-code admin app, letting developers and non-technical users manage content and data without building a backend from scratch. Founded on a project Ben Haynes started in 2004 and incorporated as a company in 2020, Directus has surpassed 30 million downloads and is used by organizations including Adobe, Bose, Tripadvisor, AT&T and the U.S. Navy.
Glide is a San Francisco no-code app builder that turns spreadsheets and databases into mobile and web apps without writing code. Founded in 2018 by four former Xamarin engineers and launched out of Y Combinator's Winter 2019 batch, Glide lets anyone build software from data they already have. Since 2023 the company has leaned hard into AI - adding Glide AI, AI agents, and plain-language app generation - to pursue its stated mission of putting software creation into the hands of a billion new creators.
Abel Mengistu is the cofounder and CEO of FlutterFlow, the low-code visual app builder that has enabled over 2 million users to create production-ready Flutter applications without deep coding expertise. A former Google senior software engineer who worked on Google Maps and ATAP hardware, he co-founded FlutterFlow in 2020 with Alex Greaves after a failed restaurant-recommendation startup taught them the real bottleneck was app development complexity. Accepted into Y Combinator's Winter 2021 batch after applying past the deadline, they famously survived 'No-sleep November' to build FlutterFlow 1.0 in a single month. The company raised a $25.5M Series A from GV (Google Ventures) in January 2024, has grown to 173 employees, and in 2025 launched Dreamflow - an AI-powered builder that generates production-ready app screens in roughly 10 seconds.
