The methodology behind every question

Distil's interview process is grounded in five proven startup frameworks. Each one brings a different lens to your idea, and together they give you a complete picture.

These aren't buzzwords. They're the same tools used by the best startup mentors, accelerators, and venture firms worldwide.

Why these five frameworks?

Most idea validation is shallow. People ask their friends, get polite encouragement, and start building. Months later they discover nobody actually wants what they've made.

Each of these frameworks attacks a different blind spot. The Mom Test stops you from asking leading questions. Jobs-to-be-Done makes sure you understand why customers switch. Lean Validation forces you to test assumptions before committing. The Value Proposition Canvas checks whether your solution actually fits the problem. Customer Discovery gets you talking to real people instead of guessing.

Distil weaves them together into a single conversation. During the early phases, we lean on the Mom Test and JTBD to understand the problem. As we explore your solution, the Value Proposition Canvas and Lean Validation take over. When we assess your market, Customer Discovery principles guide the questioning. By the end, all five contribute to your score.

🎯

Jobs-to-be-Done

Clayton Christensen · Christensen Institute · Book: Competing Against Luck

People don't buy products. They hire them to make progress in their lives. A person doesn't buy a drill because they want a drill; they want a hole in the wall. JTBD looks past demographics and features to understand the real reason someone would switch to your solution.

Forces of progress

Push: Pain with the current situation that makes someone want to change.

Pull: The appeal of a new, better solution.

Anxiety: Fear of the unknown, risk, learning curves.

Habit: Comfort with the way things are, switching costs.

For someone to switch, push + pull must exceed anxiety + habit.

How Distil uses it

During early conversation, Distil explores what progress your customer is trying to make. It asks about struggling moments, switching triggers, and whether the job is functional, emotional, or social. This shapes your Problem Clarity score.

Key principles
  • Focus on the job, not the customer segment
  • Competing with non-consumption is the hardest sale
  • Map all four forces before building
  • The job stays stable even as solutions change
  • Find the struggling moment

The Mom Test

Rob Fitzpatrick · momtestbook.com · Book: The Mom Test

If you ask your mum whether your business idea is good, she'll say yes. Not because it is, but because she loves you. The Mom Test is a set of rules for asking questions that even your mum can't lie to you about. Talk about their life, not your idea. Ask about specifics in the past, not hypotheticals about the future.

Good vs bad questions

Bad: "Do you think this is a good idea?" / "Would you buy this?" / "How much would you pay?"

Good: "Tell me about the last time you dealt with this problem." / "What did you do about it?" / "How much does this cost you in time or money?"

How Distil uses it

The Mom Test shapes every question Distil asks, especially in early phases. When you make a claim about your customers, Distil pushes for concrete evidence. "You said small businesses struggle with this. Can you tell me about a specific conversation where someone described that struggle?" It never asks "is this a good idea?" because the answer would be meaningless.

Key principles
  • Never mention your idea until you understand their problem
  • Seek disconfirming evidence actively
  • Ask "why" five times to reach concrete motivations
  • If they haven't tried to solve it themselves, it's probably not a real problem
  • One deep conversation beats a thousand surveys

Lean Validation

Eric Ries · theleanstartup.com · Book: The Lean Startup

Every business idea is a bundle of assumptions. Lean Validation says: find the riskiest assumption and test it before you build anything. Don't spend six months building a product only to discover nobody wants it. Spend six days running an experiment instead.

Evidence hierarchy

Weak: People say they're interested (opinions)

Medium: People take action (sign up, share email)

Strong: People pay money or invest significant time

Strongest: People repeatedly use and refer others

How Distil uses it

During solution exploration, Distil asks you to identify your riskiest assumption and what evidence you have for it. It distinguishes between opinions ("people said they'd use it") and behaviour ("people paid for a beta"). This directly feeds your Idea Maturity score.

Key principles
  • Identify your riskiest assumption before building anything
  • An experiment without a success metric is just a demo
  • Opinions are not evidence; behaviour is evidence
  • If everything is working, you're not testing hard enough
  • Pivot or persevere, but never ignore the data

Value Proposition Canvas

Alexander Osterwalder · strategyzer.com · Book: Value Proposition Design

The Value Proposition Canvas is a visual tool for checking whether your product actually fits what your customer needs. On one side: the customer's jobs, pains, and gains. On the other: your product's features, pain relievers, and gain creators. The magic is in the mapping between the two.

Customer profile vs value map

Customer Profile: Jobs (what they're trying to do), Pains (what frustrates them), Gains (what success looks like)

Value Map: Products/services (what you offer), Pain relievers (how you reduce pains), Gain creators (how you deliver gains)

Fit happens when every pain reliever maps to a real pain and every gain creator maps to a real gain.

How Distil uses it

When exploring your solution, Distil checks whether your features address specific customer pains and gains, not just vague "improvements." It asks: "You mentioned your customer struggles with X. How specifically does your product address that?" This shapes your Solution Potential score.

Key principles
  • Start with the customer profile, not the value map
  • Not all jobs, pains, and gains are equal; rank them
  • Every feature must map to a real customer need
  • Fit is not a one-time event; revisit regularly
  • A proposition that addresses everything addresses nothing

Customer Discovery

Steve Blank · steveblank.com · Book: The Four Steps to the Epiphany

Steve Blank's foundational insight: no business plan survives first contact with customers. Customer Discovery is the process of getting out of the building and testing your hypotheses with real people. It's not about confirming what you believe. It's about finding out what's actually true.

Pivot signals

Customers describe a different problem than you expected.

They care about different features than you planned.

Your target segment isn't reachable or willing to pay.

A different customer segment responds more strongly.

The problem exists but isn't painful enough for a new solution.

How Distil uses it

During the deep dive phase, Distil asks whether you've spoken to real people with this problem. How many? What did they say? Have you found patterns? It also checks whether you've identified alternatives your customers have tried and why those failed. This feeds into all three scoring dimensions.

Key principles
  • Talk to real people, not proxies
  • Seek patterns across conversations, not validation from one
  • Your first idea about who the customer is will probably be wrong
  • Distinguish between "nice to have" and "must have"
  • Discovery never truly ends
