Building the wrong thing is expensive. Most teams don’t fail because they can’t build — they fail because they build too early, without evidence.

A focused 3–4 week validation sprint
Week 1 — Framing
Align on problem, assumptions, and success criteria. Define target users and beta cohort. Identify the highest-risk questions to validate.
Weeks 1–2 — Prototype
High-fidelity AI-assisted prototype (web or app). Designed to feel real, not like wireframes. Instrumented with feedback and behavioral tracking
Weeks 2–3 — Beta
Release to your users. Embedded feedback at key decision points. Capture what users do — not just what they say
Week 4 — Evidence
Synthesize behavior + feedback. Identify risks, opportunities, and false assumptions. Deliver a clear recommendation and iteration plan
Every validation sprint includes:
01
High-fidelity interactive prototype
02
Embedded feedback and usage tracking
03
Guidance on who to invite and what to measure
04
Real-world beta impact data from your audience
05
Executive-level findings report
06
Clear go / no-go recommendation
07
Prioritized iteration roadmap
Each engagement is a fixed-scope validation sprint, delivered in 3–4 weeks.
