Architecture and design then fix the company brain structure, tool contracts, model assignments and the evaluation plan, written as documents your team reviews before build starts.
Build runs in sprints, typically USD 40k-90k over 6-10 wks for agent work, with code in your repositories, environments in your cloud and demos at the end of every sprint.
Launch covers monitoring, cost controls and rollback paths, followed by team AI training so developers and operators can run the system without outside help. Ongoing support starts from USD 2,500/mo for 10 hrs and covers tuning, model updates and new tool integrations.
Every stage ends in a handover artifact, which means knowledge moves into your team continuously rather than arriving in a single handover at the end.
