What is the AI Flow Sprint and how does it work?

The AI Flow Sprint is a 4-week, $15,000 fixed-price engagement on surinder.design. It ships the single most important AI flow in your product, live on a staging URL your engineers can fork. Week 1 decide and scope, week 2 design every state and the prompt architecture, week 3 build, week 4 refine and hand off. One designer-engineer, no handoffs.

The Sprint exists for founders who don't have time for a discovery quarter. The price is fixed ($15,000), the scope is fixed (one flow, every interface state, the trust and control layer, the prompt and behavior architecture where the flow needs it), the timeline is fixed (4 calendar weeks), and the deliverable is fixed (a working build on staging your engineers can fork). It is the smallest unit of real AI shipping that's still useful to a real business.

Pricing structure: $15,000 total. Milestone payments during the build. No hourly billing. No scope-creep invoices. If the scope grows beyond one flow, you move into the AI-Native Product Design engagement (from $45,000) or open an Embedded Design Partner retainer ($8,000 per month, rolling).

What's included: the single most important flow in your product picked together and locked in week 1, the full flow designed across every state (idle, thinking, streaming, citations, partial results, errors, recovery), the trust and control layer, the prompt and behavior architecture, a working build on staging your engineers can fork, repo and walkthrough handoff, and 2 weeks of post-ship support. Booking is a 30-minute scoping call. No pitch deck needed.
