Software that grows chamber by chamber.
Nautilus Tech Labs is a small studio that designs and builds AI features, mobile apps and web apps, from the first sketch to the App Store.
A nautilus never starts over.
It builds a larger chamber, seals the one behind it, and carries every chamber as it grows.
Why we chose the name. We build software the same way: one small, finished release at a time, each one tested and sealed before the next, larger one begins.
Every chamber, still in place.
Cut a shell in half and its whole history is there: every chamber the animal ever built, each one larger than the last. Good software keeps that record too. Versioned, tested, nothing thrown away.

What we build
Three kinds of work, often in the same project. Start with whichever one solves today's problem.
What it is
- Applied AI
- LLM features, agents and search over your own documents
- Mobile apps
- Native iOS and Android apps, or one codebase for both
- Web & automation
- Web apps, dashboards and the glue between your tools
Built with
- Applied AI
- Claude, OpenAI and open models, with retrieval and evaluations
- Mobile apps
- Swift, SwiftUI, React Native and Expo
- Web & automation
- TypeScript, React and Cloudflare Workers
A good first chamber
- Applied AI
- One assistant that answers from your own documents
- Mobile apps
- A first release with sign-in and one core flow
- Web & automation
- One weekly manual task, automated
How we test it
- Applied AI
- Against a set of real questions before launch
- Mobile apps
- On TestFlight and Play testing, with real users
- Web & automation
- Side by side with the manual process
After launch
- Applied AI
- Cost tracking, monitoring and model upgrades
- Mobile apps
- Store updates and crash fixes
- Web & automation
- Hosting, monitoring and maintenance
Ownership and price
- All three
- You own the code from the first commit. Each chamber gets a fixed quote.
First, we listen.
A call about the problem, not the technology: who it is for, what they do today, and what would make it worth building.
Then we build the smallest chamber.
One useful release, scoped in weeks rather than months, with a fixed quote before any work starts.
You use it, and we measure.
Real people and real data. We watch what gets used and what gets ignored, and write it down.
Then the next one, a little larger.
Each release builds on the last. Nothing is thrown away, and you can stop after any chamber.
What are you building?
Pick what fits, add a few lines, and we'll reply within two business days.
