How to Apply PMF (Product-Market Fit) to Your Commerce Business

At StoreHero, we provide commerce hacks combining Shopify and growth hacking.

When working on commerce hack projects for new products or services, we always go through a PMF (Product-Market Fit) process.

Many of you have probably heard of PMF, but few have actually put it into practice. In this article, we'll walk through the specifics of PMF and how to incorporate it into your commerce business.

StoreHero leverages its proprietary growth platform to support business growth through fine-grained operations that manual management simply can't achieve, along with the large-scale execution of growth initiatives.

What Is PMF (Product-Market Fit)?

First, PMF refers to the state in which you've found where the customers who will buy your product actually are.

Pinpointing exactly when you've achieved PMF can be difficult, but I believe PMF is reached when you have a genuine, concrete understanding of these three things:

• Who: Which customers are you targeting?
• What: What product or service are you offering?
• How: What is your value proposition?

Building a Strong Hypothesis

Before embarking on your PMF journey, formulate a hypothesis around the three points: Who, What, and How.

The hypothesis is essentially: "If I sell this kind of product to these kinds of people with this kind of pitch, it should work."

A hypothesis starts as a personal, one-sided assumption, but if it's grounded in established theory along with personal experience and addresses the following three criteria, it tends to be much more accurate:

• Is it based on a truth that only you know?
• Is it aligned with current trends?
• Is it adapted to changes in the platform landscape?

Let me briefly explain each of these below.

Is It Based on a Truth That Only You Know?

This is a well-known concept from "Zero to One" by Peter Thiel, co-founder of PayPal.

Why is a hypothesis based on a truth only you know so valuable? A simple four-quadrant framework makes this self-evident.

First, a hypothesis based on false premises will inevitably lead to the wrong conclusion — so that's out.

Equally, a hypothesis based on a truth that everyone already knows tends to lead to businesses in a red ocean. Without significant capital or proprietary technology, it's very difficult to win in those spaces.

On the other hand, building a business on insider knowledge from your previous industry or business experience dramatically increases your chances of finding a blue ocean.

A common example: "There's no product on the market that truly fits this niche customer segment." If you can identify a market like that, there's real potential.

Is It Aligned with Current Trends?

Being aligned with trends is also, I believe, a prerequisite.

Unless you have the kind of influence to create trends yourself, fighting against them as a single company is simply inefficient.

I've been involved in startups and new business ventures several times. Businesses that rode the trend tend to exceed expectations, while those that didn't — no matter how talented the team — struggled to grow.

Is It Adapted to Changes in the Platform Landscape?

Shifts in platforms present critical opportunities.

I've worked in IT for over a decade, and the industry has seen major platform shifts — from PC to mobile, from on-premise systems to cloud services.

When platforms change, the products and services that thrive on them change too.

A clear commerce example: the types of products that sell well on marketplaces differ from those that perform best on independent e-commerce stores. Similarly, what sells through Google Search differs in nature and approach from what sells on Instagram.

Validate with an MVP

Once you've formed a hypothesis about who to target, what to offer, and how to pitch it, it's time to validate.

Start by directly interviewing people in your immediate circle who are close to your target customer profile. I personally reach out to acquaintances via Facebook or Twitter DMs and ask them a few questions.

Once your hypothesis has been refined through these interviews, build a minimal product or service. Since the goal is simply to validate demand, the more minimal it is, the less waste there is.

This minimal product built purely for validation is called an MVP (Minimum Viable Product).

MVPs come in many forms. A famous example: online shoe retailer Zappos launched without any inventory — just a website — to sell shoes.

When an order came in, they'd purchase the shoes from a nearby shoe store and ship them, then accumulate feedback from customers.

AirBnB validated demand for its service using only a landing page — using an LP as the MVP is a very common approach.

In commerce, the two most common patterns are:

• Build a prototype, offer it to a small group, and collect feedback.
• Create a concept video and gather feedback from potential customers.

The latter pairs very well with crowdfunding.

The Build, Measure, Learn Loop

The Build, Measure, Learn loop involves releasing an MVP, collecting customer feedback, incorporating that feedback into an improved MVP, and repeating this cycle as you develop your final product.

By cycling through this loop, you progressively clarify who to target, what to offer, and how to pitch it — working toward PMF.

Don't Overthink It — Sell First, Then Build

The key to reaching PMF is to not get caught up in making things look polished, and to adopt a "sell first, then build" mindset.

Early hypotheses and MVPs are rough by nature, so interviews and pitches often don't get a great response — or are sometimes ignored entirely.

If you let that bother you and try to polish things up, your interviews and pitches get delayed. You'll often think "let me refine this a bit more before reaching out," but in most cases, the time spent polishing would be better spent interviewing and pitching — collecting feedback from real customers.

A "sell first, then build" mindset leads to better PMF outcomes.

After Achieving PMF

Once you've successfully achieved PMF, you move on to executing growth initiatives based on the AARRR model.

I'll explain the AARRR model separately, but the key point is this: if you haven't achieved PMF, pouring effort into ads or site optimization will rarely lead to monetization.

Conversely, once PMF is achieved, conversion rates start high from the beginning, and repeat purchase and referral initiatives tend to be far more effective.

Shopify offers more than 3,000 apps (Shopify app store) and a robust API ecosystem (Shopify developers), enabling a wide range of selling strategies. With PMF in place, you can maximize the full benefits of what Shopify has to offer.

Summary

PMF is a race against time. It's rare for an unproven product or service to receive ample budget and time upfront.

You need to achieve PMF as quickly as possible and move to execution.

To do that, adopt a "don't overthink it — sell first, then build" mindset and validate your hypotheses rapidly. We at StoreHero are here to support your PMF journey, whether domestic or international.
