4CXT is a one-person AI lab in San Diego. The agents write the code. The founder decides what is worth building, and reviews everything before it ships. Two products are live.
4CXT Inc. · est. 2026 · say it: for context
4CXT builds and runs SaaS products with a team of one. There are no employees. There is a founder with twenty years of product work, a set of AI coding agents, and a process that makes the agents better every week instead of just faster.
The process has two halves. Planning uses BMAD: a brief, a PRD, a UX spec, and an architecture, argued out by specialist agents before a line of code exists. Building uses compound engineering: plan, work, review, ship, and then write down what was learned so the next build starts smarter. Every solved problem becomes a document the agents read before they plan the next one. That is the compounding.
What gets built here is narrow on purpose. A product has to come from a pain the founder has actually lived, hold a wedge one person can defend, and run as a business one operator can keep running. If it needs a sales team, it is not a 4CXT product.
Both run on AWS under the 4CXT organization. Both were planned, built, and are operated with the process above.
git push → a live Google Doc. Comments in, commits out.Agents and engineers write specs in Markdown. Leadership reviews in Google Docs. TandemDoc keeps both sides in the same document, refuses to overwrite a comment it cannot preserve, and leaves a receipt of what happened to the version the reviewer actually read.
Fly to work. Let the agent do the rest.Travel operations for people who fly to work every week. It books the best refundable hotel as a hedge, rebooks when a better rate appears, and can unwind an entire travel week with one decision.
I have spent my career building software automations that help customers. I have worked at AWS, Intuit and I am a two time startup founder.
4CXT is where I build the things I kept wishing existed, with agents doing the building. I hold a strong opinion that the human review step/process is our primary bottleneck and I am working on solutions to that problem.
