Build working software exceedingly fast in Solar

Lumenary develops Solar, a tool to build full-stack apps alongside many LLMs on a canvas, where you can freely remix features and try design variants. We provide infra (auth, DBs, storage, servers), or you can integrate with your own. Deploy in a click. Lumenary was founded by four best friends who met at Dartmouth, with experience from Jane Street, IMC, and Palantir. They've published research in venues like NeurIPS, and have deployed software managing billions of dollars, petabytes of data, and a lot of LLM tokens.

Solar: An infinite canvas for vibe-coding production apps

TL;DR

Solar lets small teams collaborate with AI agents to build and deploy production apps in minutes. Like Figma, but no mockups—just real software with live data and backend Python functionality. Built by our full-stack AI agent, powered by your imagination.

Why this, and why us?

Hi everyone! We’re Vivek, Dan, John, and Ziray: the team behind Lumenary. We met each other during our first few weeks at Dartmouth and have been best friends ever since. We’ve lived together, worked together, traveled the world together, and have even summited some notable peaks together (don’t ask about Mount Shasta).

Our team brings together engineering from Palantir, Jane Street, IMC Trading, and Flatiron Health. We’ve built enterprise-grade AI products, a capital allocation system that controls billions, a data engine that processes petabytes–we all build and deploy software quickly in contexts where it cannot fail.

Solar began as an internal tool that we used to ship enterprise demos faster than any tool on the market. We decided to productize and focus on Solar completely.

The Problem

We’re a team of four engineers who’ve used nearly every AI-powered app builder. Projects started off great, but we found ourselves in an endless loop of “revert, and try again.” Most of our time was spent waiting and hoping as the LLM made changes one-at-a-time.

Even when the app seemed to work, it was unclear what were real features versus frontend demoware. We lacked an understanding of the architecture, dataflow, and what vulnerabilities were left open. It felt like these platforms had prioritized making neat frontends and bolted on real functionality as an afterthought.

What we do

We loved three things:

  • Figma’s flexibility — work on many designs with many people
  • Cursor’s power — write production code with LLMs
  • Retool’s safety — ship apps that you know work

We combined those to make Solar.

Solar’s AI agents collaborate alongside you on a multiplayer canvas. You can see the relationships and data flow between database tables, backend Python logic, and frontend pages.

Solar makes apps production-worthy by combining LLM-generated code with deterministic code generation for databases, services, and authentication. This makes your apps maintainable and deployable past the MVP, and able to integrate nicely with existing infrastructure.

We’re the most agentic platform on the market: Solar will read logs, interact with your application, and work for minutes or even hours unattended to get it perfect.
