Customer Discovery template — free

Four copy-paste blocks that take you from hypothesis through 20 interviews to decision. Paste into Notion, Google Docs, or any tool.

Short answer

What goes into a customer discovery template?

Four blocks: a hypothesis document you keep internal, an interview guide, a synthesis matrix and a decision record. Paste them into Notion or Docs — but the synthesis matrix wants a spreadsheet, so themes can be sorted as they appear.

The short version

Hypothesis doc, interview guide, synthesis matrix, decision record — four blocks, copy and paste
Never show the hypothesis doc to an interviewee. Telling people what you are testing is how you get it confirmed instead of tested
The synthesis matrix belongs in a spreadsheet rather than a document, so themes can be sorted and filtered as they emerge
You have enough interviews when the same three to five themes repeat across twelve or more, and the last three surfaced nothing new
Still hearing new themes at interview twenty means the hypothesis or the recruiting was off — usually a segment defined too broadly

Block 1: Hypothesis doc

Write this BEFORE you talk to anyone. It's what you're testing. Treat as falsifiable claims.

# CUSTOMER DISCOVERY — HYPOTHESIS DOC Initiative: [Name] Owner: [Name] Date: [YYYY-MM-DD] ## Customer Hypothesis We believe our customer is: - Role: [specific job title] - Company: [size, industry, stage] - Geography: [region, language] - Behavior: [what they do today that shows fit] ## Problem Hypothesis We believe their problem is: - Description: [1-2 sentences, specific not generic] - Severity: [why it's painful, not just annoying] - Frequency: [how often it happens] - Current solutions: [what they do today + why it falls short] ## Solution Hypothesis We believe our solution will work because: - Mechanism: [how our solution addresses the problem] - Differentiator: [why us vs alternatives] - Why now: [why this is timely] ## Falsifiable claims (ranked by risk) 1. [Most risky claim — if false, kill] 2. [Second-most risky claim] 3. [Third-most risky claim] 4. [...] 5. [...] ## What would falsify each claim 1. [Specific evidence that would kill claim 1] 2. [...]

Block 2: Interview guide

5-phase structure with sample questions. Copy once, customize per interviewee.

# CUSTOMER DISCOVERY — INTERVIEW GUIDE Interviewee: [Name] Role: [Title @ Company] Date/Time: [YYYY-MM-DD HH:MM] Recording consent: [✓ / Not given] ## 0–5 min: Warm-up - "Tell me about your role and what your week typically looks like." - "How long have you been doing this work?" ## 5–20 min: Context - "What's the biggest challenge you're dealing with right now?" - "Walk me through how your team is structured." - "What does success look like in your role this quarter?" ## 20–45 min: Past behavior (THE MEAT) - "Tell me about the last time [problem] happened. Walk me through the day." - "How often does this come up?" - "What did you do about it?" - "What worked? What didn't?" - "What was the cost when this isn't solved?" ## 45–55 min: Current solutions + WTP - "How do you currently solve this — even as a workaround?" - "What tools or methods have you tried?" - "How do you currently spend money or time on this?" - "What's the budget process for tools like this?" ## 55–60 min: Wrap + commitment - "Anything I should have asked but didn't?" - "Who else faces this problem that I should talk to?" - "Would you be willing to try an early version when we have one?" - "Would you put down a deposit / book a follow-up?" ## Notes during interview (live) [Capture key quotes verbatim here]

Block 3: Synthesis matrix

Best in Sheets/Excel. Each row = one interviewee, columns = themes. Sort + filter as patterns emerge.

# SYNTHESIS MATRIX | Interviewee | Date | Problem severity 1-5 | Frequency | Current solution | Spending today | WTP signal | Commitment? | Key quote | Tags | |-------------|------|----------------------|-----------|------------------|----------------|------------|-------------|-----------|------| | [name 1] | | | | | | | | | | | [name 2] | | | | | | | | | | | ... ## Theme tags (build organically as you go) - problem-severity-high - problem-severity-low - workaround-spreadsheet - workaround-existing-tool - wtp-strong (deposit / LOI / calendar) - wtp-weak (verbal interest) - wtp-zero (free alternatives sufficient) ## Pattern tracking After every 5 interviews, write 2-3 sentences: - What new theme emerged? - What theme got reinforced? - What hypothesis is starting to break?

Block 4: Decision record

Output of the Discovery phase. Either PROCEED to Validation, PIVOT, or KILL.

# CUSTOMER DISCOVERY — DECISION RECORD Initiative: [Name] Date: [YYYY-MM-DD] Interviews completed: [N] Decision: PROCEED / PIVOT / KILL ## Hypotheses outcomes | Original hypothesis | Status | Evidence | |---------------------|--------|----------| | [hyp 1] | Confirmed / Falsified / Mixed | [quotes / counts] | | [hyp 2] | ... | ... | ## What we learned (3 bullets, surprising) - [Insight 1] - [Insight 2] - [Insight 3] ## What we got wrong (1-2 bullets) - [What we believed that wasn't true] ## Decision rationale [2-3 paragraph rationale tied to evidence above] ## Next steps (if PROCEED) - Move to Customer Validation phase - MVP scope: [...] - Pricing hypothesis: [...] - Activation milestones: [...] ## Pivot direction (if PIVOT) - New customer hypothesis: [...] - New problem framing: [...] - Re-run Discovery with [N] more interviews ## Postmortem (if KILL) - Saved [estimated time/money] - What this rules out for related ideas - Where we'll look next

Get a head start on Block 1

The hypothesis doc is where most teams get stuck. We built GoNoGo as a 15-min voice session that helps you articulate hypotheses you didn't know you had — pressure-tests them against synthetic personas before you spend 6 weeks recruiting real interviews.

Frequently asked questions

Where do I paste this template?+

Anywhere structured. Notion is the most common — each block becomes a page. Google Docs works for solo founders. Confluence for larger teams. The synthesis matrix specifically benefits from a spreadsheet (Sheets/Excel) so you can sort and filter as patterns emerge.

Should I share the hypothesis doc with interviewees?+

No. The hypothesis is what you're testing — sharing it leads them to confirm it. Keep it internal. Interviewees should learn nothing about your hypothesis until after the interview ends (and even then, only if you're asking for follow-up commitment).

How do I know when I have enough interviews to make a decision?+

When the synthesis matrix shows the same 3–5 themes across 12+ interviews, with no surprising new themes in your last 3. If you're still hearing new things at interview 20, your hypothesis or recruiting was off — likely customer segment was too broad.
