How We Work
From first call to production — in four steps.
A repeatable process that keeps you in control at every stage, with zero handover gaps.
- 01
Discovery Call
We spend 30–60 minutes understanding your business, data, and goals. No jargon, no pitch — just straight answers on what AI can and cannot do for you.
- 02
Solution Design
Our engineers map the architecture: model selection, data pipeline, integration points, and a realistic timeline. You get a written spec before any code is written.
- 03
Build & Iterate
Weekly demos, short sprints. You see progress every step of the way and can redirect at any checkpoint — no black-box waterfall delivery.
- 04
Deploy & Support
We handle production deployment, monitoring and ongoing maintenance. Your team gets training, runbooks, and direct Slack access to our engineers.
