You have an AI app idea and a deadline. Let's build the version people pay for.

We design and build AI apps for web and mobile: chat assistants, document tools and AI copilots for your users. A real product with real users, shown to you in weekly demos.

## Problems we solve

- Our AI app is a wrapper anyone could copy: A chat box on top of an API isn't a product customers will pay for.
- The API bill grows faster than our revenue: Every new user costs money and nobody planned for it.
- The answers are wrong often enough to scare users: One confident wrong answer and the user stops trusting the app.
- We built it fast with AI tools and now it's breaking: The prototype worked. Now real users, payments and data are hitting it.

## What we build

- Chat and assistant apps: Assistants that answer from your content, take actions and hand over to a person
- Document and data tools: Upload, search, summarize and pull data from PDFs, contracts and records
- AI features for your users: Writing help, suggestions and automation inside your existing product
- Cost and quality controls: Model routing, caching, usage limits and answer testing

## How we work

- Discover (1 week): We define the user, the core job the AI does and how the app makes money. You get a written plan and a fixed price within 48 hours of our first call.
- Prototype (2-3 weeks): We build a working version of the core AI feature and test it with real users.
- Build (4-8 weeks): We build the full app with accounts, payments, admin tools, usage limits and analytics, released in two-week sprints.
- Improve (Ongoing): We watch usage and costs, tune prompts and models, and ship improvements based on what users actually do.

## Results

- Elite Quiz: Trivia app with AI opponents and AI-personalised question picks. Built with React Native and Socket.io for real-time play.
- Growfone: Our own AI business phone: calls, WhatsApp, SMS and AI follow-ups in one place. Live product.
- Coding Assistant Platform, Austin: Developer coding-assistant platform built as microservices. The client reports $2M+ ARR within 2 years.

## Questions

### How do we stop AI costs from eating our margin?
We estimate cost per user before we build, use smaller models where they do the job, cache repeated work and set usage limits. You can see running costs on a dashboard from day one.

### Can you rescue an app we already started?
Yes. We start with a code review, keep what works and fix what doesn't. Many teams come to us with an AI-built app that half works. Starting over is rarely the answer.

### Who owns the app and the prompts?
You own 100% of the code, prompts, data and accounts. We sign an NDA before you share anything and set everything up in your own cloud and model provider accounts.

### How will we know the project is on track?
You see working software in a demo every week. You get a written plan before we start, and we tell you early if anything will take longer or cost more.
