MVP vs PoC: What Should You Build First?

A proof of concept (PoC) and a minimum viable product (MVP) serve distinct purposes. A PoC aims to answer the question: can this work? Conversely, an MVP seeks to discover whether a specific group of people will find it useful enough to sustain a business. This critical distinction impacts both founders and engineering teams. When the primary risk involves technical or operational uncertainty, a PoC is the appropriate starting point.

Identify the core technical or operational question, design a narrow and temporary experiment, and measure the key outcome. If the risk is eliminated, the idea may require a different approach or be abandoned. PoCs should avoid unnecessary features such as production authentication, billing, analytics, polished UI, or support processes.

In contrast, an MVP is designed for situations where the main uncertainty pertains to user behavior. The objective is to establish the most basic loop that one type of user can experience: a real user encounters a specific problem, completes a useful workflow, and demonstrates a reason to continue using the product. An MVP can be technically simplistic, provided it delivers a tangible result to the user and encourages return.

To make a practical decision, list the top three assumptions behind the concept. Classify each assumption as feasibility (can we make it work?), desirability (does the user want it?), or viability (can it become a repeatable business?). If feasibility is the dominant unknown, initiate a PoC. If user interest has been confirmed and feasibility is addressed, construct the smallest MVP.

If both uncertainties persist, conduct a time-boxed technical spike and conduct five to ten user interviews. Remember that neither a PoC nor an MVP supplants the need for customer feedback. To gauge success, measure the technical outcome for a PoC (accuracy, latency, failure rate, cost per transaction, or integration reliability).

For an MVP, evaluate user behavior, such as activation, completion of the core task, repeat usage, time to value, and the quality of user feedback. Although revenue can be a valuable indicator, early signals can also include a user who modifies their workflow or introduces a colleague without prompting. Ultimately, keep both artifacts minimal.

A PoC eliminates technical uncertainty; an MVP establishes a learning loop with users. Choose the artifact that addresses your primary unknown, define the evidence required beforehand, and cease expanding once the desired outcome is achieved.
