How we work
A process built for shipping.
Four stages, run sequentially or rolled together. Lightweight enough to start in days, structured enough to scale.
- Step 01
Discovery
A focused engagement to map the problem, the data, the constraints and the smallest valuable thing to build first.
1–2 weeks
- Step 02
Design & architecture
We design the product and the system together — UX, model selection, retrieval, evals — so engineering doesn't surprise the business.
2–3 weeks
- Step 03
Build
A senior team ships in tight loops. You see working software early and often, with evals and observability in from day one.
6–12 weeks
- Step 04
Launch & iterate
We ship to production, instrument what matters and stay close — improving prompts, retrieval and UX with real user data.

How are your engagements priced?
We work on fixed-scope discovery sprints and milestone-based build engagements. We share clear estimates up front and revisit them as scope is learned — no open-ended hourly billing.
