What Counts as a Real Commitment in Customer Discovery

A split scene: on the left, a founder and a potential customer at a whiteboard sketching a calendar with blocks of time and a dollar sign; on the right, a scorecard with rows for 'time', 'money'.
Key points

Key points

  1. 1A real commitment is a costly action a potential customer takes now, such as a scheduled meeting with a decision-maker, a signed letter of intent, a pre-payment, or a public referral.
  2. 2Vague enthusiasm and hypothetical "I would buy" statements are not commitments and should be scored at zero.
  3. 3Score each commitment by cost (time, money, reputation) and by whether it is unconditional.
  4. 4Treat partial and conditional commitments as leads to convert with one specific follow-up ask, not as proof.

Why enthusiasm is not evidence

Most customer conversations end with a pleasant signal: the person nods, says the problem is real, and asks you to keep them posted. That feels like progress. It usually is not. Harvard Innovation Labs frames demand validation around three blunt questions: does the customer recognize the problem, are they actively looking for a solution, and do they have budget to solve it (Harvard Innovation Labs). None of those is answered by a compliment.

The reason is structural. People are polite, and in an interview they are imagining a perfect product at no cost to themselves. That is why the Mom Test asks you to avoid opinions about your idea and reconstruct real past behavior instead (Harvard Innovation Labs). Past behavior has a price tag: last time the problem occurred, what did they actually do, and what did it cost them.

Todd Jackson's research on how companies like Flexport, Vanta, and LaunchDarkly validated their ideas makes the same point: founders who gained confidence did so by pushing past conversation into something a customer had to give up to participate (Lenny's Newsletter). So use one definition throughout:

A commitment is a specific action a potential customer takes now that costs them time, money, or reputation, and that they would not take for an idea they did not care about.

Everything else is a conversation.

Score commitments on two axes

Two questions separate a real commitment from a polite one. How expensive is it for the customer? And is it unconditional?

Cost comes in three currencies. Time is cheapest and easiest to fake, so it only counts when it is scheduled and involves the right person. Money is the strongest signal in most markets and the easiest to verify. Reputation is the most underused: a customer who introduces you to a peer or posts publicly on your behalf spends social capital they would not spend lightly.

The condition axis matters just as much. "I will pilot this in Q3 if it integrates with our warehouse system" and "I will pilot this in Q3" describe different levels of belief. The first is a real signal wrapped in a real risk. It does not count until the condition is met or converted into a deposit.

A workable scoring rule:

CommitmentCost (0 to 3)Unconditional (0 to 3)ScoreHow to read it
"Sounds great, keep me posted"000Nothing. Do not log it as a lead
20-minute call with a user, no next step112Weak. Ask for a decision-maker
Meeting scheduled with the budget holder235Real. Confirm it in writing today
Signed letter of intent with a price range224Strong if it names a date and a buyer
Deposit or pre-payment, even small336The strongest ordinary signal
Public case study or referral to a named peer325Strong, and it produces warm leads
"We will pay if you add SSO"303Conditional. Convert the condition or discount it

The scoring rewards deposits above everything, because money is the only currency that cannot be given by accident. Referrals sit close behind, because a referral to a named peer both proves belief and generates the next conversation.

It also gives you a decision rule. If a segment produces no commitment scoring 4 or above across roughly ten conversations, the problem is probably not urgent enough for that segment, however much they liked the demo. If you see three commitments at 5 or above, you have enough to justify a bounded build. Adjust the thresholds to how expensive your product is.

Specific asks by product type

Generic advice fails because what counts as expensive varies by product. A consumer who gives an email address has given you almost nothing. An enterprise buyer who books a second meeting with their CFO has given you a great deal.

B2B software

B2B has the richest menu because the buying process is itself a series of commitments. In rough order of strength:

  1. A scheduled session with the economic buyer, not just the end user. Insist on a calendar invite with a named attendee.
  2. Access to real data or a real workflow, even read-only. This is a time and reputation commitment, because someone approves it internally.
  3. A letter of intent naming a price range and a target start date.
  4. A paid pilot. 100tasks treats paid pilots as standard validation evidence, and notes that a paid pilot validates willingness to test, not willingness to renew (100tasks). Price it small enough to clear a discretionary budget, large enough that someone signs.
  5. A reference call with another of their customers, or an intro to a peer at a comparable company.

Avoid the pilot with no money and no success criteria. That is free consulting for the buyer and a signal of roughly zero. If they will not pay, ask what internal approval payment would require, then ask for that introduction.

Consumer apps and prosumer tools

Consumer commitments are hard to make expensive, so manufacture cost. The staged approach of two hours on desk research, twenty hours on conversations or a landing page, and only then two hundred hours on a build is a useful discipline here (Isabella Pennington). Commitments worth counting:

  • Joining a waitlist that requires a qualifying form, not just an email. The qualification is the cost.
  • A refundable pre-order or deposit with a clear refund date.
  • Referring a named friend who also signs up. KickoffLabs treats referrals as real validation because they move a signup from passive interest to advocacy (KickoffLabs).
  • Booking a call. For consumer products this is a surprisingly high-cost ask and a good filter.

Be careful with waitlists. KickoffLabs says plainly that a signup is not a paying customer and warns against over-reading a waitlist (KickoffLabs). A thousand signups is a channel test. A deposit page that takes real cards is closer to proof.

Marketplaces

Marketplaces need two commitments, one per side, and supply is usually easier to test. A seller who lists an item commits time and, in many categories, reputation. Commitments to ask for:

  • A real listing with real inventory and a real price, and whether they keep it live.
  • A refundable booking fee from buyers. A fee converts curiosity into intent in a way a "notify me" button never will.
  • A manual, concierge run for a small number of buyers before matching at scale. Harvard Innovation Labs describes this approach as validating problem and solution before automating (Harvard Innovation Labs).

Supply commitment predicts viability better than demand surveys, because a seller who lists inventory has thought about shipping, returns, and pricing. A buyer who says "I would use this" has thought about nothing.

Hardware and physical products

Hardware commitments are the most legible, because crowdfunding normalized the pre-order. Ask for:

  • A refundable pre-order at a stated price with a delivery window you can miss gracefully.
  • A paid prototype evaluation for a business buyer, invoiced at cost plus a small margin.
  • A design partner agreement with a purchase order or committed quantity.
  • For industrial products, a site visit where the customer shares measured operational data: downtime, throughput, cost per unit. That is a time and reputation commitment and often more valuable than a signature.

One caveat: pre-orders validate willingness to pay at a price, not at a cost. Run unit economics separately, because the classic hardware failure is a popular product with a negative margin.

Services and consulting

For services the commitment is the engagement. Stage it:

  1. A paid discovery session or diagnostic. This is the cleanest test: will they pay for your thinking before you have built anything?
  2. A signed scope for a small first engagement, with a deposit invoice.
  3. A public testimonial or a named referral, the highest-value commitment for a business whose whole acquisition channel is reputation.

Services have an advantage worth exploiting: deliver the first engagement manually and you learn more in two weeks than six months of research would teach you. Automate once you know which parts the customer values (Harvard Innovation Labs).

How to ask without pressuring

The ask should be a natural next step, not a test the customer can fail. Three practices make it work.

First, reconstruct a recent, specific event before asking for anything. Alloy's question guide recommends covering what triggered action, what the current approach costs, and what evidence a buyer needs before changing behavior (Alloy). By the time you ask for a deposit, you should know what they spend today.

Second, name the ask and the reason. "We are building this for six design partners, and participation means a small deposit and two hours a month. Want one of the six slots?" This is honest and makes declining easy, which is what you want: an easy no beats a difficult maybe.

Third, offer a smaller version if they hesitate. If they will not pre-pay, ask for the decision-maker meeting. If they will not book that, ask for a referral. Log which ask they accepted, because the level is your score.

One ethical note. Fake door testing, where you show a button for a feature that does not exist and measure clicks, is a legitimate demand test with a reputation cost if handled badly. ConfigCat's guidance is to lead with transparency, say the feature is under consideration, and offer a notification when it ships (ConfigCat). Userpilot warns that in a young product a poorly handled "coming soon" page can damage trust before it forms, so space repeated tests far apart for the same segment (Userpilot). A click is also a weak commitment, closer to 1 or 2 on the scale. Use fake doors to recruit people for the real ask, not as final evidence.

Handling partial and conditional commitments

Most early data is partial. Treat it as an instruction to make a follow-up ask, not as proof.

A partial commitment is a commitment on one axis only: two hours but no budget holder, or a referral but no willingness to pilot. Score it for what it is, then ask for the missing axis: "Would you introduce me to whoever owns this budget?" If they will not, that tells you something about their authority or belief.

A conditional commitment is more interesting, because the condition is the deal talking. Sort conditions into four buckets:

Condition typeExampleWhat it meansNext ask
Integration or technical"If it connects to our CRM"Real requirement, real riskTechnical session with the system owner
Price"If it is under what we pay now"Purchase possibleTarget price in writing; compare to your costs
Timing"If it is ready before our audit"Deadline-driven, possibly urgentThe date, and what happens if you miss it
Approval"If the CFO signs off"You have not met the buyerThe intro to the CFO

The decision rule: a conditional commitment scores at most 3 until the condition is met or converted into something unconditional. Convert by asking for something that survives the condition. For a timing condition, ask for an LOI with the date on it. For an approval condition, ask for the meeting. For a price condition, ask for a refundable deposit at the target price.

Discount one variant entirely: the condition that is vague and unmeasurable. "If it is more robust" and "if it saves us time" are not conditions, they are politeness. Ask what number would count as saving time. If they cannot give one, the conversation is over for now.

Patterns beat single data points after tagging. Kromatic's guidance is to tag notes with recurring themes and look for signals like seven of ten interviewees describing the same behavior (Kromatic). Do the same with commitments: a spreadsheet with one column per commitment, its score, and its condition type. If the highest scores are time commitments from users and there is nothing from buyers, you have a channel problem no amount of conversation will fix.

A worked example

Suppose you sell scheduling software to regional clinics and have run 12 discovery calls. Here is a scored log.

ClinicBest commitmentScoreCondition
A30-minute call with practice manager3None
BSigned LOI at list price, start in 60 days4Timing
CDeposit of one month's fee6None
DReferral to a peer clinic owner5None
E"Would pilot if it syncs with our EHR"3Integration
F to LEmail signups, no follow-up0 to 1None

Read the numbers, not the enthusiasm. Two commitments (C and D) are unconditional and strong. One (B) is a strong conditional with a date. One (E) is a condition you may or may not satisfy, and it does not count until you hold a technical session with the EHR owner.

The decision: this is enough to run a bounded pilot with C and B if B's date can be met. It is not enough to justify building the EHR integration, because one integration condition in twelve calls is a segment question, not a product question. Ask every clinic in the next round about their EHR setup. If five of ten raise it, the integration becomes the product.

The same logic scales across product types, and it scales better with a system of record than with memory. If you are building AI into the product and want to test a pricing or workflow hypothesis quickly, a single API for text, image, audio, and embedding models lets you stand up a working test rather than a mockup (Quanta Inference). If the real question is whether you can build fast enough to test at all, that is a different problem, and one a specialist can take on with you (Quanta).

The next step is yours: rewrite one discovery script so it ends with a specific, sized ask, add a commitment score column to your notes, and run ten conversations. If nothing scores above 3, you learned something valuable and cheap. If several score 5 or 6, you have earned the right to build.

FAQ

FAQ

What is the difference between a discovery interview and a commitment?

Discovery uncovers the problem, the buying process, and what the customer does today. A commitment is a separate action the customer takes at real cost. You need the interview to know which ask is appropriate, and the commitment to know whether the interview meant anything.

How many commitments do I need before building?

There is no universal number, but a workable rule is three or more commitments scoring 5 or above from one narrow segment. Fewer means you are building on conversations. More, and you are probably delaying a build you should start.

Is a letter of intent enough?

An LOI is strong when it names a price range, a buyer, and a date. It is weak when it says "we are interested in exploring." Before counting it, check that someone with budget authority signed, and that missing the date would be noticed.

How should I treat a referral?

Score it highly, because it costs the customer reputation and produces a warm next conversation. Verify it: a named person who actually took the meeting counts, while an offer to "introduce you to someone" that never arrives scores zero.

What if a customer gives me a condition I cannot meet?

Say so directly, then ask what would make them buy anyway. If the answer is still the condition, park the customer, note it, and track how often it recurs. A recurring condition is a roadmap item; a one-off is a lost deal and should not reshape the product.
