You've got that spark – a great idea for a product, app, or tool that could solve a problem, improve efficiency, or address a need! But before you invest heavily in building it out, how do you know if that core idea is truly viable, technically feasible, or worth pursuing? Building a full solution feels like too much right now, but you need something real – more than just mockups – to test the fundamental concept, gather initial feedback, demonstrate its potential, or just confirm it works for your specific use case.
This is where early-stage ideas often get stuck. You need to move quickly, validate affordably, and get tangible results without months of development. That's where working with a specialized PoC development company makes a difference.
Our Proof Of Concept (PoC) service is designed exactly for this stage, and to ensure cost predictability, we provide a fixed rate once the scope is clearly defined.
View Sample ProjectsWhat is a Proof Of Concept?
Our Proof Of Concept (PoC) service is a focused, rapid development offering designed to bring the absolute core of your product idea to life quickly for initial validation and feasibility testing. It's about building the essential 1-2 features needed to test the fundamental viability of your concept, rather than constructing the full application. Think of it as a working sketch – just enough to prove the core interaction, demonstrate technical feasibility, or validate a key value proposition.
Fast Turnaround
See your core idea working and test its viability in just 5-10 days (depends on the scope), letting you quickly validate your concept.
Core Functionality Focus
We build 1-2 essential features that demonstrate the fundamental value and feasibility of your concept.
Predictable Scope, Clear Investment
We define a clear, limited scope upfront, allowing for a focused effort and a transparent understanding of the investment required to validate your core concept.
Complete Ownership
You receive the source code and full ownership of the PoC we build. We primarily use open-source components that grant you these rights, ensuring you have a clear path forward.
Is a Proof Of Concept Right for You

This service is ideal for those who:
Have a clear idea for a web or mobile application
Need to validate the core concept or a single key feature's viability
Want something tangible to show users, investors, or partners very quickly
Are working with a limited initial budget for development
Need to confirm technical feasibility for a specific interaction or function
If you need a quick, tangible prototype to get crucial early feedback or to verify technical feasibility, the Proof Of Concept service is designed for you.
How We Build Your Proof Of Concept
Our process is strictly streamlined for speed and clarity at this early validation stage:
Quick Scope Lock
We start with a brief chat (often just 30-60 minutes) to understand your core idea. To make this session most effective, please come prepared to discuss the primary problem you're solving and the 1-2 key features you believe are essential to prove your concept. Together, we agree on these features. For concepts where core viability can be tested with a very limited feature set, we aim to define a scope that allows for rapid demonstration, often within about a week. A clear, limited scope upfront is key!
If your initial idea requires more than 1-2 core features for a meaningful PoC, we can discuss a custom scope and a tailored approach to fit your needs. Our goal is to find the right starting point for you.
Rapid Development Sprint
Our expert developer(s) focus intensively to build the agreed-upon core features and basic setup. The development duration aligns with the PoC's defined scope; for tightly focused concepts, this phase is often completed in approximately 5 business days. We value your input and will communicate with you through your preferred channels (e.g., email, quick calls) if we have questions or need brief feedback during this phase. Rest assured, we're committed to delivering on the agreed scope and will not abandon you if unforeseen minor complexities arise within that scope; we'll communicate transparently.
Delivery & Handover
We provide you with the working prototype (deployed to a basic demo environment, typically our Azure account, where it can remain accessible for a defined demo period – we'll confirm this with you) and the source code for the developed features.
Quick Review
A brief follow-up (e.g., 1-3 hours) to hand over the files, demonstrate the Proof Of Concept, answer your initial questions, and discuss potential next steps.
What Your Grassequal PoC Delivers (And Why It's Your Best First Step)
When you engage Grassequal for a Proof of Concept, you're not just getting code; you're getting clarity and a tangible way to test your vision. Here’s what this focused engagement typically includes and why it’s often a smarter starting point than jumping straight to a Minimum Viable Product (MVP):
What’s Typically Included in Your PoC:
Our rapid PoC development is designed for speed and essential validation. You’ll generally receive:
A Scoping Session
A collaborative session to clearly define the core aspect of your concept that needs validation and agree on the essential features and scope for your PoC.
Focused Development
Dedicated development effort from our experienced team to build the agreed-upon features. The specific timeline for development will be determined based on the defined scope.
A Working Prototype
A basic, functional prototype (web or mobile, depending on your idea) that demonstrates the agreed-upon core features in action.
Source Code
Full ownership of the source code for the features developed within the PoC scope.
Demo Environment Setup
Initial deployment to a basic demo environment (often our Azure account) so you can see and share your working PoC.
Handoff & Review Session
A brief session to hand over all assets, demonstrate the PoC, answer your questions, and discuss potential paths forward.
Post-Handoff Support
We'll address any critical bugs directly related to the agreed PoC scope that you might find shortly after delivery.
Why a PoC Before an MVP
It can be tempting to build a more complete Minimum Viable Product (MVP) right away, but starting with a PoC offers distinct advantages for early-stage ideas:
Focus on Feasibility, Not Features
A PoC is laser-focused on answering a critical question: 'Is this core idea technically feasible?' or 'Does this fundamental concept work as envisioned?'. It validates 1-2 make-or-break assumptions with minimal investment. An MVP, on the other hand, is a broader first version of your product for real users, containing a larger set of features to solve a core user problem.
Speed to Insight
Our typical PoC aims for delivery in about a week. This rapid turnaround allows you to quickly learn, iterate, or even pivot without spending significant time and resources on features that might not be core to the initial validation. MVPs naturally take longer to develop.
Cost-Effectiveness for Validation
Because a PoC is strictly limited in scope, it’s a much smaller, more controlled investment to test your riskiest assumptions. This allows you to 'fail fast and cheap' if an idea isn't viable, or gain confidence before committing to the larger budget an MVP requires.
Reduces Risk for MVP Development
The learnings from a PoC – whether it's about technical challenges, user reactions to the core concept, or even internal alignment – can significantly de-risk and better inform the development of a subsequent MVP. You’ll go into MVP planning with more concrete evidence.
In essence, a PoC is your fastest, most affordable way to test the very heart of your idea. An MVP is what you build once you have that foundational validation and are ready to engage early users with a more complete (but still minimal) solution.
What You'll Get Out Of It
Investing in a Proof Of Concept means you'll gain:
Tangible Prototype
Get something real and working to show – far more impactful than mockups for demonstrating feasibility.
Fast Viability Check
Quickly test if your core concept works, resonates with initial viewers, or is technically feasible.
Crucial Early Feedback
Get insights early, before investing heavily in further development.
Clearer Next Steps
Gain clarity on whether your idea is worth pursuing further development, needs a pivot, or should be parked based on concrete evidence. A PoC helps you make informed decisions.
Own the Starting Code
You get the source code for what was built. While a PoC focuses on speed and validation, the code will be organized, and depending on the outcome, parts may serve as a useful reference or starting point for future MVP development.
Ongoing Support
Includes three 30-minute follow-up calls (one per month for 3 months) to discuss your progress, answer further questions about the PoC, or provide light strategic advice as you consider your next steps.
Added Value & Your Path Forward
This Proof Of Concept (PoC) development service is a powerful way to start your validation journey. If the results are positive and you choose to proceed with a larger development project with GrassEqual, we offer a clear path forward.
