Customer validation: VAL-Q experiments and interview plans

If you are building a company and feel lost about customer validation experiments, you are not alone. This phase exists so your Strategy Pack stays honest—not pretty.

What this phase is really about

Customer validation turns assumptions into evidence before expensive scale. You design interviews and experiments with clear pass/fail thresholds. Startups avoid building unused features; enterprises pilot SKUs with measurable learning contracts.

In Sculptor, CustomerValidationAgent keeps the conversation anchored to Customer validation so you do not mix this work with other phases. That separation is how consultants run engagements: one room, one decision set, one artefact pack.

Why teams skip this (and regret it later)

Teams confuse NPS with validation. Skipping VAL-Q means funding and marketing scale stories nobody tested—with churn discovered after CAC is spent.

Questions this phase must answer

• Which assumption, if wrong, kills VP-001?
• What behavior proves willingness to pay?
• Which segments get distinct experiment designs?
• What sample size is honest for our stage?
• How do we avoid leading questions in interviews?
• What will we do if results are inconclusive?
• Which artefacts update when validation fails?
• How do sales pilots feed validation data?

Deliverables you should leave with

Customer validation artefacts define interview guides, experiment designs, and success thresholds (VAL-Q ids)—linked to riskiest assumptions from brainstorm and strategy.

• VAL-Q-001 interview guide with scoring
• Experiment brief with metrics and duration
• Assumption trace matrix to BRAIN and VP
• Decision rules for pivot, persevere, or stop

What to prepare before you start

• PROT demos or concierge MVP access
• ICP list from SLS-001
• Analytics events from product if live

Who should own the answers

Product and UX research lead validation; sales recruits participants ethically; sponsors commit to acting on negative results.

How this connects to the rest of your pack

Examples from the real world (names changed)

A beverage ritual brand VAL-Q-001 showed users wanted smaller packs, changing packaging backlog before national retail.

A performance sportswear DTC experiment failed a premium price assumption early, shifting MKTG to proof-led messaging instead of discounting.
