PoC Development (Validation Phase Only)

Turn the first step of your new business into something tangible—fast.

Contract PoC development for internal reviews, validation, and market tests
Built to support decision-making—not full production

We specialize in small, time-boxed builds focused on validation—so you can decide what to do next with confidence.
PoC-only scope: we build just what you need, as quickly as possible.

Common challenges

We help you unblock the typical bottlenecks in the validation phase.

You have an idea, but nothing you can show yet

We quickly turn concepts into demos and prototypes you can present.

You need a demo for internal stakeholders

We design deliverables that are easy to understand—even for non-engineers.

You want to validate demand before full development

We build a minimal MVP you can use for interviews and market testing.

Typical vendors push the scope too big

With PoC-only scope, we intentionally keep the build lean and focused.

You need speed to run the validation quickly

We aim for “a state where you can decide” within weeks, not quarters.

What is contract PoC development?

Definition

PoC (Proof of Concept) is a prototype build to validate feasibility and market demand for an idea or technology.
This service is not about shipping a finished product—it’s about producing the evidence and artifacts needed to decide your next action, in a short time frame.

Typical use cases

  • Demo for internal approval / executive review
  • Prototype for user interviews
  • MVP for market validation
  • Artifacts for investment and go/no-go decisions

Value & strengths

PoC-focused

We avoid waste by building only what’s necessary for validation.

Short timelines

Typically delivered in a few weeks to 1–2 months.

Designed for decision-making

The goal is not “build and done” but “ready to decide what’s next.”

Clear deliverables

We emphasize demos and explanations that are easy to share internally.

What we can build

Lean web service build

A simplified version focused on the core validation hypothesis.

Prototype with admin panel

Enough to visualize operations and validate workflows.

Landing page + form + admin flow

End-to-end lead capture and management for validation.

Technical spikes (external APIs)

Feasibility checks for third-party integrations.

UI/UX-first screens

Designed for usability in interviews and testing.

Other requests welcome

We’ll propose the minimal build based on your decision criteria.

Process

1 Discovery

We align on context, constraints, and validation goals.

2 Define the PoC goal

We clarify what you need to decide and define PoC-only success criteria.

3 Minimal scope design

We reduce the build to the smallest set that supports validation.

4 Build

We implement quickly while keeping quality that supports next steps.

5 Delivery & walkthrough

We deliver with explanations optimized for internal sharing.

* The direction can be adjusted mid-way depending on what you learn.

FAQ

Q. Can you also do the full production build?

A. Yes—after the PoC, we can discuss the next phase separately.

Q. Is it okay if requirements aren’t clear yet?

A. Absolutely. We can help define the goal and scope from scratch.

Q. How does payment work?

A. We usually start after an upfront bank transfer. After you confirm completion, we deliver once the remaining balance is received via bank transfer.

Q. Can we sign an NDA?

A. Yes, we can.
