iBusiness and the paperwork problem
A lending company learned to automate its own paperwork. Now iBusiness wants banks to build software around the way they actually work.
The Postgres Company That Let AI Write the Signups
It started as the open-source answer to Firebase. Then AI coding agents adopted it as their default backend, and Supabase doubled its valuation to $10.5 billion in eight months.
The town that refused to demolish its own future
In 2014, two Cape Girardeau residents talked the city out of demolishing a downtown building and started southeast Missouri's first tech incubator inside it. A decade later, Codefi trains AI workers, builds startups as a co-founder, and pulls venture capital into places the coasts forget.
stagewise
stagewise is a frontend coding agent that lives inside your running web app on localhost. Instead of switching between a browser and an IDE, developers click on a UI element, describe the change in plain language, and stagewise edits the actual source code in the local codebase. Started by Julian Goetze and Glenn Toews and part of Y Combinator's Summer 2025 batch, it began as an open-source, framework-agnostic toolbar that has been downloaded more than 130,000 times and starred over 4,800 times on GitHub.
Lovable puts the idea person in charge
Two failed launches taught Lovable that a clever demo was not enough. Its next act gave people with a problem a way to build the software that solves it.
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.
Emergent
Emergent is an AI app builder that turns plain-language ideas into working, monetizable software. Its autonomous coding agents handle design, coding, testing, deployment, and scaling behind the scenes, giving non-technical users something that feels like a cloud-based engineering team. Founded by twin brothers Mukund and Madhav Jha and backed by Khosla Ventures, SoftBank, Lightspeed, Google, and Y Combinator, Emergent reached roughly $50M in ARR within seven months of launch and counts more than 5 million users across 190+ countries.
Sekai
Sekai is a San Francisco Bay Area consumer platform where anyone can build software just by describing it. Users type a prompt and get a playable, shareable mini-app - a game, quiz, utility, poll or interactive story - in seconds, then play, remix and share what others make. Founded in 2024 by serial entrepreneur Lucky Zhang, Sekai (Japanese for 'world') began as an AI anime fan-fiction tool and pivoted into general-purpose app creation as AI coding models improved. By mid-2026 users had created more than 15 million mini-apps, with roughly 200,000 new ones a day, and the company had raised about $26 million across Seed and Series A rounds from Khosla Ventures, Connect Ventures, a16z speedrun, Mayfield and others.
Supernova
Supernova is an AI-powered platform that turns a company's design system into structured context that both people and AI coding agents can use. Founded in Prague and now building a U.S. headquarters in San Francisco, it centralizes design tokens, component APIs, documentation and rules as a single source of truth, then feeds that context into tools like Figma, Storybook, Cursor, GitHub Copilot and Claude Code so product teams can prototype, hand off and ship features faster. A Y Combinator alum, it is used by hundreds of organizations including Air France, KLM, Kraft Heinz, Paramount, Mozilla, LaunchDarkly and Skyscanner.
Jabali
Jabali is a generative-AI game engine that lets people build and publish playable 2D and 3D games by describing them in plain language, no coding required. Founded in 2023 by former Meta, Amazon, Zynga and Microsoft gaming executives alongside AI researchers, the company wants to do for game creation what ChatGPT did for writing. It raised a $5M seed round led by BITKRAFT Ventures with Sony Innovation Fund and Sapphire Sport participating, and opened its Jabali Studio platform in early access in October 2025.
Shuttle
Shuttle is a Rust-native cloud platform that lets developers ship backends without writing infrastructure files. You annotate what you need in code - a database, secrets, a web server - and Shuttle provisions it and deploys to the cloud. Founded in 2019 and shaped by Y Combinator's Summer 2020 batch, the company is now repositioning as an 'AI platform engineer' that handles the deployment step where AI coding tools like Cursor, Copilot and Lovable leave off. It has drawn more than 20,000 developers and over 120,000 deployments, and raised a $6M seed round in October 2025.
TestSprite
TestSprite is a Seattle-based startup building an autonomous AI testing agent that validates AI-generated code. Its agent plugs into AI IDEs like Cursor, Claude Code, and VS Code via an MCP server, then autonomously writes test plans, generates and executes tests in the cloud, diagnoses failures, and feeds fixes back to the coding agent. Founded in 2023, TestSprite has raised $8.2M total, including a $6.7M seed led by Trilogy Equity Partners in October 2025, and serves 35,000+ users. It positions itself as the 'testing backbone' of the AI-native development era.
Woz
Woz is a San Francisco AI platform that acts like a technical cofounder in the cloud - designing, coding, testing, deploying, and maintaining production-ready mobile apps for non-technical founders. Unlike no-code tools that stop at prototypes, Woz combines specialized AI agents with human engineering review to ship real, business-ready apps straight to the app store. Founded by MIT engineers Ben Collins and Brad Eckert, the YC W25 company raised $6M in seed funding in October 2025.
Anything starts where the demo stops.
An AI app builder learned that generating code was only the beginning. The real work was getting ordinary people all the way to a product someone could use - and pay for.
Windsurf
Windsurf (formerly Codeium, originally Exafunction) is a Mountain View-based AI coding company that built one of the first agentic AI-native IDEs, powered by its Cascade agent. Founded in 2021 by MIT classmates Varun Mohan and Douglas Chen, it grew to over 1 million developers and $82M ARR before a dramatic July 2025 split: Google paid roughly $2.4B to hire its founders and license its technology, while Cognition (maker of Devin) acquired the remaining product, brand, team, and customer base. In June 2026, Cognition relaunched the Windsurf IDE as Devin Desktop, an agent command center for managing local and cloud coding agents.
Replit
Replit is a browser-based software creation platform that has evolved from a collaborative cloud IDE into one of the leading agentic AI coding companies. Its Replit Agent lets anyone - engineer or not - go from a natural language prompt to a deployed, production-ready application. Headquartered in Foster City, California, the company now serves more than 40 million users and reached a $9B valuation in 2026.
