Key MVP Development Definitions

If you’re doing it right, Product-Market Fit (PMF) is embedded throughout your product design, build, and launch. So first, let’s clarify some essential terms to make sure we're all on the same page.

Proof of Concept (POC) or prototype

A POC or prototype is an early-stage version of a product, often not user-facing. It serves to validate a concept or idea within the project, focusing on technical feasibility or design viability. The two terms are often used interchangeably and can represent anything from design blueprints to a bare-bones version of the product. The key is that it’s primarily for internal use and feedback to evaluate the product's potential.

Minimum Viable Product (MVP)

An MVP is a user-facing, market-ready product. It's a lean version of your envisioned product, focusing on the core features necessary to provide a complete user experience. Whether a startup MVP or a new product within an established enterprise, it allows the organization to test the market, gather feedback, and iterate, offering a comprehensive yet streamlined functionality.

Minimum Marketable Product (MMP)

An MMP is the first marketable iteration of your product, expanding upon the MVP. It includes a clear value proposition and additional features appealing to a broader audience. While an MVP tests the basic concept, an MMP enhances it for broader market appeal, with a product roadmap reflecting longer-term goals.

Market validation

This is the process of confirming that your product idea is a solution to a genuine problem faced by your target audience. It involves various research and testing methods to ensure that your product concept holds real-world value and appeal. Having this is essential before looking for MVP development services.

Product-Market Fit (PMF)

PMF refers to the alignment of your product with the needs and preferences of a specific market. It's about ensuring that your product resonates with users to the extent that they are willing to use and pay for it. Achieving this fit means your product has successfully found its place in the market, meeting user expectations and demands.


For the purpose of this article, when we talk about a ‘client’, we’re referring to the organization we’re working with to build an MVP.


A ‘user’ is how we refer to the end user of the product, those who will use, test and eventually pay for the tool or software created.

At NaNLABS, we approach these concepts from a partnership perspective - which means we’re invested in each stage and every element of the process. Need some guidance on streamlining your scope whilst still achieving PMF? That’s what we’re here for. Looking for a third-party solution to reduce the cost of your MMP? We’re already on it.

Now that we’ve got that cleared up, back to Product-Market Fit.

6 Myths of Product-Market Fit

The concept of Product-Market Fit is often shrouded in ambiguity, mainly because it doesn’t hold a one-size-fits-all definition. PMF varies significantly across different businesses, industries, and target audiences. This variability makes PMF difficult to define which makes it even harder to measure and test effectively.

To define what PMF is, it’s easiest to start with what it’s NOT. Here, we’ll explore the diverse meanings and debunk some common myths surrounding it.

Myth 1: PMF is a one-time, measurable goal

Contrary to popular belief, PMF isn't a single milestone that can be checked off a list - and it is not just the responsibility of marketing or product development teams. It's a continuous process, a blend of strategies and insights gathered over time. Your product will evolve, as will markets, customer needs, and competition. PMF involves constantly gauging whether you’re aligning with these demands, rather than just hitting a one-off target.

Myth 2: More features guarantee better PMF

Adding an abundance of features might seem like a surefire way to improve PMF, but this is a misconception. PMF is about addressing specific user problems effectively, not feature overload. Sometimes, excessive features can even detract from user satisfaction.

Myth 3: Rapid user acquisition equals strong PMF

While a surge in user sign-ups can be indicative of interest, it's not the sole measure of PMF. Other qualitative factors like user satisfaction, retention, and loyalty are equally crucial. A high number of users doesn’t always translate into a sustainable or loyal user base.

Myth 4: PMF instantly leads to revenue

It's a common fallacy that successful PMF immediately results in revenue generation. While PMF can indicate a viable business model, monetizing user interest can be a separate challenge. High user engagement doesn’t always equate to immediate financial gain.

Myth 5: There’s a single “silver bullet” solution

The belief in a “magic feature” that will skyrocket the number of paying users is another myth. PMF is not about finding a single solution but about understanding and fulfilling user needs holistically.

Myth 6: The client knows best

While clients are often experts in their field, assuming they have all the answers to their users’ needs without extensive user interaction is a pitfall. PMF demands a deep understanding of their user needs, great “listening” skills, and the ability to uncover patterns in user feedback - which often requires direct and continuous user engagement.

When does Product-Market Fit Take Place?

We’ve already established that Product-Market Fit isn’t a one-time event confined to a single phase of product development; it's an ongoing process that spans various stages. Still, understanding when and how to evaluate PMF is crucial for aligning your product with market needs and user expectations. These are the key milestones where PMF should be assessed and validated.

Initial market research

Before any code is written or designs are drafted, understanding the market is essential. This involves analyzing the market size, potential adoption rates, and user expectations. It’s about asking critical questions: Who are your potential users? What problems do they face that your product can solve? This early stage sets the foundation for PMF by aligning your product vision with market realities.

POC/ prototype stage

As you move to creating designs and mockups, this stage offers an opportunity for early validation. Here, a small pool of potential users can interact with your product concept, providing feedback on its usability and appeal. This stage is crucial for making adjustments based on user input, ensuring the product is shaping up to meet market expectations.

Testing early versions

Once you have a working version of your product, it’s time to get it into users' hands. This stage is about observing how users interact with your product, what features they use most, listening to their feedback, and finding any annoying bugs. This real-world usage data is invaluable for refining PMF.

MVP launch and beyond

The MVP launch is a significant milestone but not the final destination in achieving PMF. Post-launch activities like conducting demos, collecting feature ideas, addressing bug reports, and actively seeking and acting on user feedback are critical. As the market changes and user needs evolve, so should your product. 

Metrics for Measuring Product-Market Fit

Determining whether your product has achieved Product-Market Fit requires careful consideration of various metrics. These metrics not only provide insights into the current state of your product's market alignment but also guide you in setting and refining your goals.

User engagement metrics

  • Number of active users: Regular user count, both overall and segmented (daily, weekly, monthly), gives a clear picture of your product's engagement level.

  • Frequency of usage: How often users engage with your product can indicate its necessity and appeal.

  • Session duration: Longer usage sessions can signify higher engagement and a better fit.

  • Unsubscribes or churn rate: A high rate of users leaving can point to a misalignment with market needs.

Feedback and satisfaction metrics

  • Survey results: Surveys can provide direct feedback from users about their experience and satisfaction.

  • Customer reviews and testimonials: Qualitative feedback can offer deeper insights into user satisfaction and areas for improvement.

Growth and revenue metrics

  • Number of sign-ups: A steady increase in new users can be a positive sign of PMF.

  • Revenue growth: Sustained revenue growth indicates that users see value in your product.

  • Referral rates: High referral rates suggest that users are finding your product valuable enough to recommend it to others.

Investor-focused metrics

For products seeking investment, certain metrics are particularly important:

  • Churn rate: The rate at which you lose customers over a given period.

  • Customer Acquisition Cost (CAC): How much it costs to acquire a new customer.

  • Lifetime Value (LTV): The total revenue expected from a customer over their lifecycle.

Special considerations for B2B SaaS platforms

  • Pilot programs: For an enterprise MVP, running a pilot program can provide a wealth of data on user adoption and satisfaction.

  • Pricing strategies: Observing how different pricing models (e.g., per company or seat) impact adoption and usage within a SaaS MVP can be telling.

These metrics cover both qualitative and quantitative methods at every stage, a combination of which is needed for valuable and well-rounded feedback. By continually monitoring these and keeping a finger on the pulse of market trends, you can set goals that are aligned with your product's unique market and user base.

Tools for Measuring Product-Market Fit

The process of gathering and analyzing feedback is facilitated by a range of tools that help collect data, conduct surveys, and track user interactions. Here's a breakdown of some of the main NaNLABS-recommended tools.

User feedback and survey tools

  • SurveyMonkey & Google Forms: These platforms are excellent for creating and distributing surveys to gather user feedback. They're user-friendly and can be used to collect a wide range of data, from user satisfaction to specific feature feedback.

  • A customer feedback tool that allows users to submit and vote on feature requests. It's a great way to gauge what your users want next.

  • Net Promoter Score (NPS) surveys: A straightforward method to gauge overall customer satisfaction and loyalty.

Analytics and behavior-tracking tools

  • Google Analytics (GA): A staple in tracking website and app usage, offering insights into user behavior, engagement, and demographics.

  • Amplitude: Provides more in-depth analytics, particularly useful for understanding user interactions and engagement patterns.

  • Heatmaps: Tools like Hotjar or Crazy Egg offer visual heatmaps of where users spend most of their time on your website or app, indicating what catches their attention or causes friction.

Prototyping & stage environment tools

  • Figma: For creating clickable prototypes, allowing you to test user flows and interface designs before actual development begins.

  • Vercel, AWS Amplify (and similar tools): Using tools to easily create stage environments for mid-project demos can be crucial for gathering real-time feedback and making necessary adjustments before full-scale deployment.

CRM and customer support tools

  • HubSpot & Zendesk: These tools are not just for sales and customer support, they provide valuable insights into customer issues, preferences, and feedback.

  • Zoom or Microsoft Teams: Conducting direct interviews with users provides invaluable qualitative insights. For remote interviews, these platforms offer reliable video conferencing capabilities to ensure no feedback is missed.

  • TLDV & Fireflies: Notetaking tools help to automate the feedback-gathering process, provide additional AI insights, and spot patterns across meetings.

  • Omnichannel tools (e.g. Zendesk): Useful for consolidating user feedback from various channels, including customer support inquiries and sales interactions.

These tools, when used effectively, can provide a comprehensive picture of how well your product aligns with market needs and user expectations. It’s important to remember that PMF is not just about collecting data but about interpreting it correctly and making informed decisions based on that data.

Tips for Achieving & Retaining Product-Market Fit 

Once PMF is achieved, the focus shifts to maintaining and building upon it. This requires

✅ Continuous user engagement

Actively seek feedback by regularly communicating with users through surveys, interviews, and feedback tools, as well as tracking behavior through analytics tools. Establishing community forums or platforms for real-time user interaction also has great success stories. Our B2B SaaS client, Fluint, created a dedicated Slack channel to promote interaction, whilst, another NaNLABS client, created media content for their users with expert insights, enhancing user education and engagement.

✅ Market and competitor awareness

Keep an eye on market trends and competitor movements so you can anticipate shifts in user needs and preferences. Then, be ready to innovate and adapt your product in response to new market insights. The inability to adapt is a fast track to failure (just ask Kodak or Nokia).

✅ Fast analysis and innovation

Regularly review user metrics and feedback to identify areas for improvement and update your product swiftly to show your commitment to their needs. This responsiveness encourages user retention and satisfaction.

Tip: You don’t need to wait for a problem to create change. Avoid stagnation by introducing new features that align with user needs.

✅ Effective communication

Above all else, talk to your users. Invite feedback and discussion and keep them informed of updates, new features, or fixes to the product to build trust and loyalty.
