Market research or trust intuition?

The answer is not to choose one side, but to know which decision needs evidence before committing.

Quick summary

The entrepreneur's intuition is a good starting point for forming hypotheses, but it is not evidence for committing significant resources. Thorough research is needed when making major and irreversible decisions: repositioning, changing customer segments, raising capital, entering new markets. For smaller decisions that are reversible and low-cost, intuition combined with quick testing is sufficient, without the need for expensive research.

Quick comparison
You should choose this direction when
  • Repositioning, changing the customer base, upgrading segments, raising capital, entering new markets.
  • Significant and irreversible decisions, with a high cost of error.
  • There is feedback and sales data sufficient to answer questions.
Not needed when.
  • Minor decisions, reversible, with low cost.
  • waiting for perfect research for every small decision

The intuition of seasoned brand professionals is highly valuable, but it often answers the question "what do I think about the customer," not "what reasons do customers actually decide for." These two questions may seem similar but lead to completely different outcomes when you bet your budget on them.

Intuition is hypothesis, not evidence.

The founder often has the deepest understanding of their product. However, being too close can lead them to view customers through their own lens. When asking acquaintances to try it out and receiving positive feedback, that is not market evidence. When a few friends in the community praise it, that is an encouraging signal, not confirmation that the target segment you want to reach will buy.

The correct approach is to treat your intuition as a good hypothesis that needs to be validated. The role of research is not to replace your judgment but to confirm or refute it before committing significant resources.

When is it mandatory to conduct research?

There is a simple question for self-checking: if this decision is wrong, will the cost to fix it be high, and will it take a long time to turn back? If the answer is yes, that is a sign that you need evidence before proceeding.

  • Repositioning the brand: changing how the market perceives you is an expensive and time-consuming decision that can lead to rebuilding if done incorrectly.
  • Changing or expanding the customer base: assuming that a new group of customers will understand and price your product similarly to the old group is a significant risk.
  • Moving up to a higher segment: the buying motives and decision criteria in higher segments often differ significantly from those in the mass market.
  • When seeking funding or opening new markets: investors and partners will ask for evidence, not just listen to the vision.
  • Rebranding after a crisis: understanding how customers perceive you before engaging with them is essential.

When quick testing is enough

Not every decision requires research. Waiting for perfect data for every small step will slow down the organization and waste unnecessary resources.

  • A small, reversible decision: change the message on one channel, test new content, adjust the pricing presentation.
  • Data is already available: feedback from previous customers, sales figures, and conversion rates are sufficient to answer the questions being raised.
  • The cost of testing is actually lower than research costs: sometimes launching a small version to the market and observing the response is the fastest and cheapest way to learn.
Thorough research: suitable for major decisions that are hard to reverse, where the cost of being wrong is high. Investing time and resources is worthwhile to gather evidence before committing. It does not necessarily have to be a large-scale survey; in-depth qualitative interviews with the right people can provide most of the necessary insights.

Intuition plus quick testing: suitable for small, reversible decisions, or when data is already available. Prioritize practical learning speed over costly research. Intuition is used to set direction, while real market reactions are used for adjustments.

Research does not need to be big and expensive.

A common misconception is that "systematic market research" means hiring a large research company, surveying hundreds of people, and taking months. In reality, for the strategic decisions of small and medium enterprises, in-depth qualitative interviews with the right people are often more valuable than large-scale surveys that ask the wrong questions.

Clayton Christensen's Jobs to be Done method is a practical approach: instead of asking customers what they think about the product, ask them what problem they are trying to solve, what they have done before, and what led them to decide to change. This way of questioning turns subjective feelings into evidence of true motivations.

Positioning must be based on how customers actually make decisions, not on internal assumptions.

Common mistakes when guessing instead of asking

  • Allocating the entire communication budget to a positioning based on the founder's intuition, without validating it with real customers first.
  • Confusing the praise of a familiar majority as evidence of a broader market.
  • Hearing clients say what you want to hear instead of what they truly think: this is the natural bias of those close to the product.
  • Waiting for perfect research for every small decision slows down the entire process due to unnecessary detailed evidence.

The viewpoint of Sinh Vũ

In Sinh Vũ's S1 working process, market research and customer interviews are scheduled for weeks 2 and 3, before writing any strategies or positioning. The simple reason: Sinh Vũ respects the intuition of business owners as a valuable source of hypotheses, but does not use it as a foundation for major decisions without verification with real customers.

For small decisions during implementation, Sinh Vũ does not recommend costly research. Quick testing, observing real reactions, and adjusting is a more effective way to learn at that stage. The important thing is to know what type of decision you are facing before choosing an approach.

Frequently asked questions

How many interviews are enough to make a positioning decision?

There is no fixed number, but the principle in qualitative research is to stop when no new insights are gained from subsequent interviews. The quantity depends on the complexity of the customer file. More important than the number is the quality: in-depth interviews with the right people, asking about real buying motives, are more valuable than large-scale surveys that ask the wrong questions.

I have been selling for many years and understand my customers very well, do I still need to conduct research?

Years of experience are a valuable asset, and Sinh Vũ respects that. However, founders are often very close to the product and tend to hear what they want to hear from customers. If you are maintaining a direction that has been successful, intuition is sufficient. If you are about to make significant changes such as changing your target audience, moving upmarket, or entering new markets, a few validating interviews are still much cheaper than the cost of mispositioning.

Does systematic market research mean you have to hire a large research company?

Not necessarily. Rigorous research here means having a clear methodology and asking the right people, not necessarily large scale or high cost. Some in-depth qualitative interviews with real customers, designed with the right questions, often provide enough insights for strategic decisions, at a much lower cost than large-scale surveys.
