What is a Proof of Concept (PoC) or Proof of Principle? A crucial first step in software development

A Proof of Concept (also known as Proof of Principle) is a small-scale, functional prototype developed to validate that your idea is technically feasible and meets market demands before full investment. In business terms, PoC refers to a demonstrable verification that a product, technology, or idea can work in practice. Our PoC services reduce risk and provide tangible evidence for stakeholders.

PoC vs Prototype vs MVP: Understanding the differences for your project

While a Proof of Concept validates technical feasibility ('Can it be built?'), a prototype focuses on user experience and design ('How will it work?'). An MVP (Minimum Viable Product) is a fully functional product with core features ('Will users value it?'). Our structured PoC development process ensures your idea works technically first, creating a foundation for future prototyping and MVP development.

Our Proof of Concept Development Process

We follow a structured approach: Discovery (understanding your vision and requirements), Development (building the core functionality focused on technical validation), and Evaluation (testing, documenting results, and providing recommendations for next steps).

What is a proof of concept in software development?
A proof of concept (PoC) in software development is a small-scale, functional implementation created to verify that a software idea is technically feasible. It focuses on validating the core concept rather than delivering a complete solution. The primary goal is to determine if the technology stack, architecture, and key functionalities can work as envisioned before investing in full development.
Is proof of principle the same as proof of concept?
Yes, 'proof of principle' and 'proof of concept' are essentially synonymous terms. Both refer to the process of testing and validating an idea's technical feasibility before committing to full development. Some industries may prefer one term over the other, but in software and technology development, they represent the same methodology of creating a minimal implementation to verify that a concept is viable.
How long does it take to develop a proof of concept?
Typically, our proof of concept development takes 2-4 weeks, depending on complexity. Simple web or mobile application PoCs may require just 2 weeks, while more complex solutions involving embedded systems or advanced technologies might take up to 4-6 weeks. We focus on rapid development of core functionalities to validate your idea quickly and cost-effectively.
What's the difference between a proof of concept and a prototype?
A proof of concept (PoC) validates technical feasibility and answers the question 'Can this be built?' It focuses on core functionality and technical validation. A prototype, on the other hand, demonstrates how the product will look and function, focusing on user experience and interface design. PoCs typically precede prototypes in the development process, confirming technical viability before investing in user experience design.
How much does a proof of concept cost?
The cost of a proof of concept typically ranges from €5,000 to €25,000, depending on complexity, technologies involved, and development time required. Simple web application PoCs start at the lower end, while complex solutions involving embedded systems, AI, or blockchain may require higher investment. We provide detailed estimates after an initial consultation to understand your specific requirements.
What happens after the proof of concept is completed?
After completing your PoC, we provide comprehensive documentation of findings, technical validation results, and recommendations for next steps. Based on the PoC outcomes, you can decide to: 1) Proceed to prototype or MVP development, 2) Adjust your concept based on technical insights gained, 3) Secure funding or stakeholder approval using the PoC as evidence, or 4) Pivot to an alternative approach if technical limitations were discovered.
Can a proof of concept be used to secure funding?
Yes, a proof of concept is an excellent tool for securing funding. It provides tangible evidence that your idea works technically, reducing perceived risk for investors. Our clients report up to 50% improved investor confidence when presenting a working PoC versus a concept alone. The PoC demonstrates your commitment, validates technical feasibility, and gives investors something concrete to evaluate.
Do you offer proof of concept services for hardware and embedded systems?
Yes, we specialize in both software and embedded systems development. Our team has expertise in developing PoCs for IoT devices, connected products, hardware-software integrations, and embedded systems using platforms like STM32, nRF, and ESP32. We can create complete end-to-end PoCs that include both firmware for hardware components and accompanying software applications.
Why choose a Polish company for proof of concept development?
Poland offers an exceptional combination of high-quality engineering talent at 30-50% lower costs than Western Europe or US. Our engineers are highly skilled in both application and embedded development, with excellent English proficiency and EU-aligned business practices. Additionally, we operate in the same time zone as most European clients, making collaboration seamless while providing EU compliance and data protection standards.
How can a proof of principle or proof of concept benefit my business?
A proof of principle/concept provides multiple benefits: 1) It validates technical feasibility before major investment, 2) It reduces development risks by identifying potential issues early, 3) It helps secure stakeholder buy-in and investor funding with tangible evidence, 4) It shortens time-to-market by focusing initial efforts on core functionality, and 5) It provides a solid foundation for subsequent development phases like prototyping and MVP creation.
What does PoC mean in business and software development?
PoC stands for Proof of Concept. In business and software development, it means creating a small-scale, functioning version of an idea to verify that it works technically before committing significant resources. It's used to validate assumptions, test technical feasibility, and demonstrate to stakeholders that the concept can work in practice. PoC development helps businesses make informed decisions about whether to proceed with full-scale development.
What is the difference between a PoC and an MVP?
A Proof of Concept (PoC) and a Minimum Viable Product (MVP) serve different purposes in the development process. A PoC answers the question 'Can we build this?' by validating technical feasibility with minimal functionality, typically not shown to end users. An MVP answers 'Should we build this?' by delivering a basic but usable product with core features that can be released to early users for feedback. A PoC comes before an MVP in the development sequence: PoC → Prototype → MVP → Full Product.
How does Scrum methodology apply to Proof of Concept development?
We apply Scrum methodology to PoC development by organizing work into short, focused sprints (typically 1-2 weeks for PoCs). This approach brings structure to the exploration process with daily stand-ups, sprint planning, and demo sessions. Scrum helps ensure rapid progress, maintains transparency, and allows for frequent feedback and adjustments. For PoCs specifically, we adapt Scrum to emphasize quick validation of assumptions rather than delivering a polished product.
