A 7-day validation sprint for a micro-SaaS before you write code

Most micro-SaaS ideas fail for a boring reason: the founder spent the first week building instead of learning whether a specific person wants a specific outcome.

Here is a seven-day validation sprint that produces evidence before a code sprint. It is deliberately small. The goal is not to "prove the market" in a week; it is to decide whether the next week deserves more effort.

Day 1 — Name one narrow problem

Write one sentence in this form:

[Person with a context] struggles to [complete a job] because [friction].

Avoid a persona such as “small businesses.” Prefer “freelance designers who lose leads because proposal follow-up lives across email and WhatsApp.” A narrow problem gives you a way to find people and to recognize useful replies.

Day 2 — Make your assumptions falsifiable

List the three assumptions that must be true for the offer to matter:

  1. The problem happens often enough to be memorable.
  2. The current workaround is costly, slow, or frustrating.
  3. People will exchange money, time, or access for a better outcome.

For each assumption, decide what evidence would change your mind. For example, five people saying “I already solved that with a spreadsheet and it takes two minutes” is useful negative evidence.

Day 3 — Ask about the past, not opinions

Use short questions that invite concrete stories:

  • “Tell me about the last time this happened.”
  • “What did you do instead?”
  • “What did that cost in time, money, or missed opportunities?”
  • “What have you already tried?”

Do not lead with your solution. “Would you use an app that…” mainly measures politeness. A recent example reveals behavior.

Day 4 — Reach five relevant people personally

Send five focused messages, not a blast. Tell the truth: you are researching a narrow workflow and want a 15-minute conversation. If nobody responds, that is a signal about either your audience, message, or problem urgency.

Keep a simple log with the person, their current workaround, the exact phrase they used to describe the pain, and whether they agreed to talk again.

Day 5 — Turn the strongest pain into a one-page offer

Your page needs only four pieces:

  1. A headline that repeats the problem in the customer’s language.
  2. A tangible outcome, not a feature list.
  3. A small explanation of how it works.
  4. One action: reply, join a waitlist, reserve a pilot, or pre-order.

If you cannot explain the offer in one page, the idea is probably still too broad.

Day 6 — Ask for a commitment

The strongest early signal is not a like. It is a commitment that costs something: a calendar slot, access to real data, a pilot agreement, or a small pre-order.

Be transparent about the stage. A useful line is: “I am testing whether this is worth building. If I can solve this for you, would you be willing to reserve a pilot?”

Day 7 — Make a decision from evidence

At the end of the sprint, choose one:

  • Double down: repeated pain, a costly workaround, and at least one real commitment.
  • Refine: the pain is real but the segment, wording, or outcome needs work.
  • Stop: the evidence does not support another build week.

Stopping an unvalidated build is a win. It protects your time for the next test.

A simple scorecard

Before writing code, rate the opportunity from 1–5 on urgency, frequency, ability to reach buyers, willingness to commit, and your ability to deliver a first manual version. The total is less important than the explanation behind each number.

If you want a reusable Spanish-language guide and calculator for this sprint, I made the Kit de Validación Rápida. The same page also offers a transparent, fixed-price Express Audit for one landing page or pre-sale offer; it is paid directly in SOL and does not promise revenue.``

If you already have a defined offer and need the actual page rather than another framework, Launch Page Sprint is a fixed-scope, custom-coded landing-page build for USD 149. It includes one responsive page, focused copy, source files, and two revision rounds; it does not include paid traffic or sales guarantees.
