Customer Research — Interviews & Surveys (Primary Research)

Going to the source. Mode 2 mines what customers already said in public; this is Mode 3 — you ask. Customer research is your marketing cheat code, and the highest-signal version is talking to customers directly.

Three primary-research pillars, best used together:

  1. Video calls — deep, unstructured, follow-the-thread (this file)
  2. Surveys — broad, quantified, benchmarkable (this file)
  3. Online sleuthing — Sales Safari and watering-hole mining (see references/source-guides.md)

The First Rule of Customer Research

The first rule of customer research: you do not talk about customer research.

Keep it casual. The moment a customer thinks they're in "a research study" they perform — they give you the polished, socially-acceptable answer instead of the real one. Frame calls as a chat, not an interview. Don't lead. Don't pitch. Don't defend the product. You're there to listen and learn how they actually think, talk, and decide.

Prove yourself wrong, not right. The point of research is not validation — it's disconfirmation. Go in trying to break your assumptions, not confirm them. If you only look for evidence you're right, you'll find it, and it'll be worthless.


Sales Safari (Amy Hoy)

Amy Hoy's Sales Safari: go where your audience already congregates and observe them in the wild, without interrupting. It's structured online sleuthing — read threads, reviews, comments, and forum posts to mine four things:

Mine for What you're capturing
Pains The problems, frustrations, and workarounds they describe unprompted
Jargon The exact words, phrases, and shorthand they use — copy gold
Recommendations What they tell each other to buy, try, or avoid
Worldview Their beliefs, biases, and how they see themselves and the problem

Safari is passive (you observe) where interviews are active (you ask). Run it first: it tells you what to ask about, and in whose words. For per-platform search operators and extraction tips, see references/source-guides.md.


Customer Interviews (Video Calls)

Recruit your best customers

Don't interview whoever answers first. Interview the customers you want more of. Segment your CRM and prioritize by:

Recruitment methods, in order of leverage:

  1. Segment the CRM by the three signals above and pull a shortlist
  2. Ask sales and CS for referrals — they know who loves the product and who articulates why
  3. Always close every call with: "Who else should we talk to?" — the single most reliable way to compound your interview pipeline

Incentives

Outreach email template

Keep it short, casual, specific, and low-commitment. Not a "research study."

Subject: Quick favor — 30 min, on us

Hi [First name],

I'm [name] from [company]. I'm trying to get better at helping customers

Are you free [day] or [day] this week? Here's my calendar: [link]

Thanks either way,

Notes:


Keep Asking Why (5-Why Laddering)

The first answer is never the real answer. Keep Asking Why — ladder each response down 3-5 levels until you hit the root motivation, the business outcome, or the emotional driver. Surface answers are features; the bottom of the ladder is why they pay and why they stay.

Worked example — laddering a churn signal to NRR:

The surface answer was "we don't use reports." The root is an onboarding gap that quietly converts an expansion (NRR up) into a contraction or churn (NRR down). You can't fix "they don't use reports." You can fix re-onboarding new hires and surfacing ROI to the buyer — which is the difference between contraction and net revenue retention.

Pain points vs. passion points. Ladder for both. Pain points are what's broken and what they'll pay to escape. Passion points are what they love, brag about, and would be "very disappointed" to lose. Passion points drive retention and referrals; pains drive acquisition. Capture both in their words.


Surveys

The PMF Survey (Sean Ellis / Superhuman)

The single most useful survey question, from Sean Ellis and popularized by Superhuman's Rahul Vohra:

"How would you feel if you could no longer use [product]?"

  • Very disappointed
  • Somewhat disappointed
  • Not disappointed
  • N/A — I no longer use it

The 40% benchmark: if 40% or more of users answer "very disappointed," you likely have product/market fit. Below 40%, keep iterating. Superhuman reached 58% by engineering their roadmap around this metric — segmenting on the "very disappointed" cohort, doubling down on what that cohort loved, and converting the "somewhat disappointed" fence-sitters.

Run it as a recurring pulse, not once. Follow the core question with:

Segment every answer by the "very disappointed" cohort vs. the rest — that cohort is your true market.
