The Startup That Guarded the Back Door - Then Closed It
Internal turned the neglected admin console into a product: quicker to build, harder to abuse, and easy enough for operations teams to shape. Four years and $16 million later, its shutdown supplied the industry with a second lesson - the tool behind your tools still needs an exit plan.
Superblocks
Superblocks is a New York-based enterprise software company that lets organizations build, deploy, and govern AI-generated internal applications. Its AI agent, Clark, turns natural-language prompts into full-stack apps backed by extensible React code, while enforcing an enterprise's existing security policies, data permissions, design standards, and audit requirements. The company positions itself as the governed, IT-controlled answer to consumer 'vibe coding' tools, serving teams that need to ship internal software quickly without introducing security and compliance risk.
Appsmith
Appsmith is an open-source, low-code platform that lets developers quickly build internal tools - admin panels, dashboards, CRUD apps, and workflow automations - by dragging pre-built UI widgets onto a canvas and wiring them to databases and APIs with JavaScript. Founded in 2019 by Abhishek Nayak, Arpit Mohan, and Nikhil Nandagopal, the company positions itself as the developer-first, self-hostable alternative to closed platforms like Retool, and has expanded into AI-powered agents that give business teams context-aware automation on top of their own data.
Gumloop
Gumloop is a no-code AI automation platform that lets any employee build, deploy, and manage AI agents and workflows by dragging modular nodes onto a canvas. Where legacy tools like Zapier treat AI as one node among many, Gumloop makes AI orchestration the core primitive - connecting a company's internal data to leading AI models to complete complex, repetitive work. Founded in 2023 by McGill classmates Max Brodeur-Urbas and Rahul Behal, the company went through Y Combinator's Winter 2024 batch and raised a $50M Series B led by Benchmark in March 2026. It counts Shopify, Ramp, Gusto, Instacart, Samsara, and Opendoor among its customers.
Reflex
Reflex is an open-source, full-stack Python framework and cloud platform that lets developers build and deploy production-grade web apps entirely in Python - no JavaScript required. Founded by ex-Apple and Ancestry engineers Nikhil Rao and Alek Petuskey, the company (originally Pynecone, a Y Combinator W23 startup) wraps React components in Python so data scientists, analysts, and engineers can ship UI, backend, and deployment from a single codebase. It has grown to over a million apps built, 25k+ GitHub stars, and adoption inside Fortune 500 companies.
Glide
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.
Retool
Retool is a San Francisco-based software company that helps engineers build internal tools, dashboards, workflows, and AI-powered apps faster by combining a drag-and-drop UI builder with code (JavaScript, SQL, Python) and connectors to nearly any database or API.
