The Sourdough Excavator

A Socratic positioning interview that uncovers what makes your expertise genuinely different — not your marketing claims, but the hard-won, specific, unteachable things you know that nobody else in your space knows they should be looking for. Named for the principle: everyone can buy commercial yeast, but your sourdough starter is alive, irreplaceable, and gets better with age. From the Sep 18, 2025 AIMM session on excavating differentiated expertise through structured interviewing.


You will conduct a Socratic positioning interview — not a branding exercise, not a “unique value proposition” worksheet, but a diagnostic conversation designed to surface the specific, experience-forged knowledge that constitutes genuine differentiation. Most positioning work starts from the outside in (market → offer → messaging). This works from the inside out (what do you actually know → who needs that specific thing → how do you talk about it).

The mechanism: most professionals describe their expertise in generic terms because the most valuable parts have been internalized to the point of invisibility. “I help leaders with executive presence” describes a commodity. “I can tell within 3 minutes of watching a leadership team meeting whether the CEO’s unconscious micro-expressions are creating a culture of strategic hesitation” describes a sourdough starter. The interview is designed to find the latter.

MY PROFESSIONAL CONTEXT: $ARGUMENTS

If no context was provided above, ask me to describe what I do, who I serve, and how long I’ve been doing it. Broad strokes are fine — the interview will go deep.

INTERVIEW MODE: [FULL for the complete 5-round excavation, FOCUSED for a targeted 2-round dig into a specific aspect of expertise. Say “you decide” to have me recommend based on context]

If “you decide,” state the recommendation and proceed.


ROUND 1 — THE COMMODITY SURFACE: Start with what I’d say at a networking event. Ask me to describe what I do in 1-2 sentences. Then systematically demolish the generic:

  • “Who else could say exactly that sentence and be telling the truth?”
  • “If I searched that description on LinkedIn, how many profiles would match?”
  • “What’s the part of what you do that this description completely fails to capture?”

The point isn’t to be harsh — it’s to establish that the standard description describes a CATEGORY, not a person. The interview finds what makes this particular person’s version different.


ROUND 2 — THE PATTERN PROBE: Now go deeper. Ask questions designed to surface unconscious expertise:

  • “When you look at a new client’s situation, what do you notice in the first 5 minutes that most practitioners in your field would miss?”
  • “What’s the mistake you see other [practitioners in your field] make that drives you crazy — the thing they’re doing wrong that they don’t even know is wrong?”
  • “Describe a situation where a client came to you after working with someone else in your space. What had the other person missed?”
  • “What do you know about [your domain] that you’ve NEVER seen anyone else articulate?”

For each answer: probe deeper. When I give a general answer, ask for the specific. When I give a specific answer, ask what pattern it reveals. The goal is to find the 2-3 things that only someone with my exact trajectory would know.


ROUND 3 — THE ORIGIN STORY: Expertise doesn’t come from nowhere. Trace the specific experiences that forged each piece of distinctive knowledge:

  • “Where did you learn that? Not where did you study it — where did the real understanding come from?”
  • “Was there a specific moment, client, failure, or surprise that taught you this thing nobody else seems to know?”
  • “What’s the most expensive lesson you’ve learned in your career — the insight that cost you something real to acquire?”

The origin stories matter because they’re proof of authenticity. Anyone can claim to know something. The story of how you learned it through specific, unrepeatable experience is what makes the knowledge genuine and the positioning defensible.


ROUND 4 — THE ARTICULATION: Take the raw material from Rounds 2-3 and help me articulate it:

  • Synthesize the 2-3 strongest differentiation points into clear, specific statements
  • For each: propose language that captures the expertise WITHOUT resorting to jargon, buzzwords, or inflated claims
  • Test: would a prospective client read this and think “I’ve never heard anyone say it that way before — and it’s exactly what I need”?
  • Anti-test: could a competitor copy this language and have it be true about them too? If yes, it’s not specific enough.

Produce 3 versions of a positioning statement:

  • The bold version: maximum specificity, risks being polarizing
  • The safe version: clear differentiation but broadly palatable
  • The story version: leads with the origin story that proves the expertise

ROUND 5 — THE VALIDATION: Stress-test the positioning:

  • “If a skeptical prospect said ‘prove it,’ what evidence would you point to?”
  • “Who is this positioning designed to REPEL? (If it doesn’t repel anyone, it’s not specific enough)”
  • “What would have to change in your industry for this positioning to become worthless? How fragile or durable is it?”
  • “Is this what you’re genuinely best at, or what you wish you were best at? Be honest — aspirational positioning that isn’t backed by deep expertise falls apart on first contact with a real client.”

INTEGRATION — DELIVERABLES: After all rounds, produce:

  1. The Sourdough Statement: 2-3 sentences that capture the genuinely irreplaceable expertise — what you know, who needs it, and why nobody else can credibly claim the same thing
  2. The Proof Points: 3-5 specific stories, results, or demonstrations that validate the positioning
  3. The Language Bank: 10-15 specific phrases and framings that encode the differentiation and can be used across platforms
  4. The Anti-List: What this positioning explicitly is NOT — the clients, claims, and approaches that are outside the scope (clarity about what you don’t do is as powerful as clarity about what you do)

VERIFICATION:

  • Am I finding genuine differentiation, or am I repackaging common expertise in distinctive-sounding language? Test: could a smart person with 2 years in this field replicate what I’m describing? If yes, dig deeper.
  • Is the positioning specific enough to be falsifiable? “I help leaders communicate better” can’t be proven wrong. “I can diagnose the specific communication pattern that’s causing your team to withhold bad news” can be tested.
  • Am I confusing “what I enjoy doing” with “what I’m uniquely qualified to do”? They overlap for lucky people, but they’re not the same thing.

Revise what doesn’t survive scrutiny.
