VENTURE DECISION GUIDE · 02

What a startup must validate before building an MVP

An MVP should be the smallest product needed to test a decisive assumption — not the first expensive expression of an untested idea.

ANSWER FIRST

Before building an MVP, a startup should validate six things: a specific user and painful situation, the current alternative, evidence of demand, the riskiest solution assumption, a reachable acquisition path and basic delivery economics. The required evidence depends on the venture; interviews alone and a polished prototype are not proof of a repeatable business.

01 · DEFINE THE DECISION

An MVP is an experiment, not a smaller final product

The purpose of an MVP is to learn whether a venture assumption survives contact with real behaviour. It is not a reward for completing a business plan, and it is not necessarily an application. A manual service, clickable prototype, landing page, concierge workflow or paid pilot can sometimes produce the needed evidence faster.

Start by writing the decision the MVP must inform: continue, change segment, redesign the value proposition, test another channel, prepare the operating model or stop. If the team cannot state what evidence would change that decision, the build scope is premature.

Agartha separates discovery evidence from build output. The goal is not to remove uncertainty; it is to reduce the most expensive uncertainty before creating the next irreversible cost.

02 · PRE-BUILD GATES

The six questions that must become testable

There is no universal interview count or validation score. Evidence quality depends on the decision, the market, the buying process and the cost of being wrong. The six gates below make the missing proof visible.

GateQuestionStronger evidence
ProblemWho experiences which painful situation, when and why?Observed behaviour, recurring workaround and consequence
DemandWill a defined buyer give time, data, access or money?Pre-order, paid test, signed pilot or qualified commitment
AlternativeWhat do people do today and why is it tolerated?Current cost, switching friction and decision criteria
SolutionWhich mechanism must work for value to exist?Prototype task completion or concierge result
ChannelCan the team repeatedly reach the buyer and user?Named route, conversion steps and acquisition constraint
EconomicsCan the venture deliver value without hiding core costs?Price test, direct cost, capacity and margin direction
03 · PROBLEM AND DEMAND

Listen for behaviour, then ask for commitment

Market research should combine existing evidence with direct research. The U.S. Small Business Administration distinguishes existing sources from direct methods such as surveys, questionnaires, focus groups and in-depth interviews. For a founder, the useful question is not whether people like an idea; it is what they do today, what the problem costs and what would make them change.

A positive interview is weak evidence when no behaviour changes. Stronger signals require something scarce: time from a decision-maker, access to a workflow, permission to observe data, a pre-order, a paid experiment or a signed pilot. A letter of intent can clarify intent but remains non-binding unless the document says otherwise.

  • Interview users, buyers and prescribers separately when they are different people.
  • Ask about the last real occurrence, not a hypothetical future preference.
  • Record current alternatives, workarounds, switching costs and budget ownership.
  • Distinguish enthusiasm, qualified intent, contractual commitment and payment.
04 · SOLUTION EVIDENCE

Test the riskiest mechanism before the full experience

A feature list mixes assumptions about desirability, usability, technical feasibility and operating capacity. Rank those assumptions by consequence and uncertainty, then design the cheapest credible test of the first one.

A prototype can test comprehension and task flow. A concierge test can test whether the promised outcome matters. A technical spike can test a difficult integration. A paid pilot can test the buying process and delivery conditions. None of these alone proves product-market fit; each resolves a narrower question.

The build brief should include the target user, triggering situation, single core job, excluded features, data boundaries, acceptance criteria, instrumentation, support route, test population, budget and decision date.

05 · DELIVERY REALITY

Validate access, feasibility and economic direction

A promising prototype can still fail because the buyer is unreachable, implementation is too heavy, regulated data cannot be used, integrations are unavailable or the price cannot cover direct delivery. These are venture risks, not details for after launch.

Before coding, map the buyer, approver, user and blocker; the channel required to reach them; the direct and third-party costs; the human work hidden behind the interface; and any legal, data, security or sector review. Model a range rather than a single optimistic forecast.

Model lineMinimum questionDo not assume
PriceWhat has a qualified buyer accepted or rejected?Stated willingness equals payment
Direct costWhat increases with each customer or transaction?Founder labour is free forever
CapacityHow many customers can the current process serve?Software removes every manual step
AcquisitionHow does a buyer discover, evaluate and approve?A large market creates a channel
RetentionWhich recurring event brings the user back?Early curiosity becomes habit
ComplianceWhich review is actually required for this context?Incorporation or hosting proves compliance
06 · GO / PREPARE / REDESIGN / STOP

Use a build gate with explicit exclusions

Proceed when the team can name the segment and situation, show credible problem evidence, identify the payer and channel, isolate the riskiest mechanism, access the inputs required for the test and define the decision the MVP will support.

Choose PREPARE when one missing dependency can be closed through research, access or technical work. Choose REDESIGN when the scope is too broad or the proposed product does not test the riskiest assumption. Choose STOP when the evidence no longer justifies the expected cost, risk or founder time.

A build decision does not guarantee traction, fundraising, regulatory approval or commercial success. It authorises only a bounded experiment with a responsible owner, budget, timeline and review gate.

Decision questions.

Short, visible answers matching the page’s structured data.

How much validation is enough before an MVP?

There is no universal interview or survey count. The evidence must be strong enough for the specific cost and risk of the next build decision, with contradictions and limitations visible.

Do founders need code to validate an idea?

Not always. Interviews, observation, landing pages, concierge services, clickable prototypes, technical spikes and paid pilots can test different assumptions before a full product build.

Does a letter of intent validate demand?

It is one signal. Its strength depends on who signed, the scope, the conditions and whether it includes a scarce commitment. A non-binding letter is not revenue or guaranteed conversion.

Is a prototype an MVP?

Not necessarily. A prototype usually tests understanding or usability. An MVP is the smallest product or service experiment that can create the evidence required for a venture decision.

Does validation prove product-market fit or fundraising readiness?

No. It reduces defined uncertainties. Repeatable demand, retention, economics and financing readiness require separate evidence.
