What We Build

We focus on a short list of services where our team has real, proven experience. We are not a generalist agency. We do web, mobile, SaaS, and MVP work — and we do it well.

Web Application Development

If your web app takes more than 2 seconds to load, half your visitors leave. We build dashboards, SaaS platforms, portals, and internal tools on Next.js and React. Clean architecture. Load times under 1 second. Built to scale from day one.

Load times: 2.5s to under 0.8sLearn more about Web Application Development

MVP Development

A real MVP is the smallest version of your product that real users can pay for. Not a prototype. We scope it down to 4-5 core features, build it properly, and ship in 4-6 weeks. Fixed price. Production-ready. No rebuilds needed.

Ships in 4-6 weeks. Paying users by week 7.Learn more about MVP Development

SaaS Product Development

SaaS needs multi-tenancy, Stripe billing, role-based access, and admin dashboards from day one. Most agencies bolt these on later. We build them in from the start so you are not re-architecting at 10,000 users.

Built to scale. No expensive rewrites.Learn more about SaaS Product Development

Mobile App Development

One React Native codebase. Two app stores. Half the cost of separate native apps. We handle everything: UI design, device integrations, App Store and Google Play submission.

50% lower cost vs. native iOS + Android.Learn more about Mobile App Development

UI/UX Design

Most design problems are not aesthetic — they are functional. Users leave because they cannot figure out what to do next. We design interfaces that are clear, fast, and built around what users are actually trying to accomplish.

Up to 35% lift in conversion rates.Learn more about UI/UX Design

Cloud Infrastructure & DevOps

Blue-green deployments. Automated rollbacks. CI/CD pipelines. Zero-downtime releases. We have taken a fintech client from 47 seconds of downtime per deploy to zero.

Zero-downtime deploys. 3x release frequency.Learn more about Cloud Infrastructure & DevOps

Why Startups and Founders Choose Us

There are thousands of dev agencies. Most have the same pitch. Here is what actually makes us different.

Senior Engineers. Not a Sales Team.

The engineers who scope your project are the engineers who build it. No account managers. No junior handoffs. Every engineer has 5+ years of production experience.

Fixed Price. No Surprises.

Hourly billing is a blank check. An estimate of 200 hours becomes 400. We give you a fixed price based on a detailed written scope. If we scoped something wrong, that is on us.

You Own Everything From Day One.

Your code lives in your GitHub from the first commit. Your app deploys to your cloud accounts. Every credential is yours. Your code is never a hostage with us.

MVPs in 5 Weeks. Not 5 Months.

We scope ruthlessly. Your 20-feature wishlist becomes 4-5 features that prove your idea. Then we ship fast. Production-ready, not a prototype. The record is 3 weeks.

A Simple, Transparent Process

Most dev agencies are a black box. You sign a contract, wait months, and hope what comes out is what you asked for. That is not how we work.

01

Discovery Call

30 minutes. You tell us what you are building and who it is for. We ask hard questions. By the end you will know if we are the right fit — we will tell you honestly if we are not.

02

Written Scope & Fixed Price

Within 48 hours you get a detailed spec — every feature, every exclusion, a fixed price. No hourly billing. No scope creep. We do not write a line of code until you approve it.

03

Build & Weekly Demos

Every Friday you get a staging URL with working software — not a progress report. You test it, give feedback, and we adjust. Problems caught in week 2, not week 10.

04

Launch & Clean Handoff

We deploy, configure monitoring, document everything, and hand over every credential and repo. We do a walkthrough session. When we are done, you own everything.

What Our Clients Say

Real feedback from founders and CTOs who have shipped with us.

"They rebuilt our patient portal in 8 weeks. Zero downtime during the migration, and our load times dropped by 70%. It is rare to find a team that actually understands healthcare compliance."

M

M. Davidson

Head of Product · Healthcare SaaS · United States

"We needed an MVP fast. They delivered in 6 weeks and it was production-ready — not a prototype we had to rebuild. The async communication worked perfectly despite the timezone gap."

J

J. Hartley

Founder & CEO · E-commerce Startup · United Kingdom

"Working with a team 12 hours ahead seemed risky at first. But their async setup meant I woke up every morning to progress updates. The dashboard now loads in under 2 seconds."

Questions We Get Asked

Straight answers. No fluff.

How long does it take to build an MVP?
Most MVPs we build ship in 4 to 6 weeks from the day we sign the scope. Some very focused scopes have shipped in 3 weeks. Some with more complexity take 8 weeks. Before we start, you will have a realistic timeline written into the scope document.
How much does it cost to build a web app?
A focused MVP with 3 to 5 core features typically falls between $8,000 and $15,000. A full web application with an admin panel, third-party integrations, and multiple user roles usually runs from $20,000 to $60,000. We give you a fixed quote after a free discovery call — no hourly billing.
Do you work with early-stage startups?
Yes. About 40% of our clients are pre-seed or seed-stage founders. We understand what runway pressure feels like. We scope projects to fit real budgets — not by cutting quality, but by cutting scope to what actually matters for your first launch.
Who will actually work on my project?
The same senior engineers you speak to before signing. There are no junior developers who get handed your project after the contract is signed. The people who scope your project are the people who build it.
How do you work with clients in different timezones?
Daily written updates in your inbox every morning, a staging URL you can test whenever you want, direct Slack access to your engineers, and a weekly video demo every Friday. We maintain a 4-hour overlap window with US East Coast, UK, and Australian Eastern Time for real-time calls when needed.
What do I own when the project is done?
Everything. The code repository lives in your GitHub account from day one. The app is deployed to your cloud accounts. Every domain, every API key, every third-party service login is yours. You also get a full README, architecture overview, and a handoff session.
Can you rescue a project another agency left in bad shape?
Yes. About 30% of our work is rescue projects — codebases abandoned by other agencies, apps with serious technical debt, or products where the founder lost access to their own code. We start with a free 30-minute code audit and give you an honest recommendation.
