Your startup deserves a real engineering foundation.
Idea → Airrow → Code → Company
How it works
Answer the CTO interview
An adaptive interview captures your product, audience, capabilities and technical decisions. Only questions whose answers change the output.
Airrow generates your foundation
A language model turns your answers into the architecture, specifications, standards, roadmap and AI context your project needs. Your stack decisions are applied exactly as you chose them; the writing around them is done for your product, not filled in from a template.
Build with your AI agents
Download your repository, open it and run one command to take it from documents to a project that runs. You stay in control of what gets built after that, one spec at a time, and your agents finally have the context of a senior engineering team.
Everything before the first line of code
Airrow doesn't build your app. It builds the foundation that makes AI-assisted development consistent, correct and fast.
Architecture
System design, database schema with RLS, tech-stack decisions
Specifications
One real spec per capability, covering requirements, edge cases and security
AI context system
CLAUDE.md and context files so your agents never guess
Why spec-driven development
AI writes code faster than any team can review it. The bottleneck moved: it is no longer typing, it is deciding. Specs are how decisions survive, and how you stay the one making them.
- Without a spec, an agent optimises for looking finished. It invents requirements you never gave it and quietly reopens decisions you made last week.
- The spec is the source of truth. Code is reviewed against it, not the other way round.
- It replaces “does this look right?” with “does this match what we agreed?”, which is a question you can actually answer.
- Decisions made once, in writing, survive the context window and the three months after it.
Already have a project?
ProAirrow is not only for the first line of code. Point it at a repository that already runs and the foundation is written around the stack that is there: architecture, specifications and AI context describing your project as it actually is. Your application code is never touched. What you choose is how the foundation lands.
Integrated
Your team sees it, and it becomes how the project is worked on.
Airrow's files take their own paths in your repository, beside your own. Anything that collides with a file you already have becomes a conflict you decide, one at a time. This is what you push, and what everyone working on the project gets.
Hidden
One folder git ignores, so the repository your team shares stays as it is.
Every generated file goes into a single folder you name, and git is told to ignore it on your machine, so nothing collides and your repository's diff stays empty. Nothing outside that folder changes: not your documents, not your branches, not a line anyone else will review. No CI comes with this one, because a workflow inside an ignored folder could never run.
Importing a project you have already started is part of Pro, and both ways of landing come with it.
