From Idea to Functional Web App — Fast.

We build and deliver modern web applications using React, Next.js and Tailwind — from concept to live prototype in just a few days.

What We Do

We design, prototype, and build custom web applications that you can demo, test, and present — fast. Whether it’s for investors, internal validation, or production rollout, you’ll get working code you can actually use.

Rapid Prototyping

We turn requirements into a functional prototype within a few days — perfect for validation or investor demos.

Full Development

Production-ready Next.js and React applications, optimized and scalable from day one.

Technical Consulting

We help define the architecture and plan for your MVP or product, even if you choose to continue elsewhere.

Our Process

1 day

From idea to wireframe

We start by understanding your requirements as quickly as possible. Within a single day, you receive a clickable wireframe showing how your app will look and behave.

3–5 days

From wireframe to functional prototype

We turn the wireframe into a fully functional web app prototype, hosted live for demo or internal review.

4 weeks

From prototype to go-live

We complete development, deployment, and final testing — delivering a production-ready web app. If it takes longer, you don’t pay extra.

Why Work With Us

Investor-Ready Prototypes

Show a real, clickable prototype to investors or shareholders. Gain traction before full development.

No Commitment

The first phase is free. You can use the prototype internally or even hand it off to another team.

Speed & Transparency

We deliver functional results in days, not weeks. You’ll see progress live on every iteration.
