About 41Stack
41Stack is a software development studio based in Pakistan. We build custom web applications, SaaS products, mobile apps, and the integrations and automation that connect them — for businesses in the UK, US, UAE, and beyond.
About
We're not only a contractor. We build, launch, and operate our own products, Fbrly and Postory. That means when you hire us you're hiring a team that has had to live with its own architecture decisions in production — on call, with real customers.
How we work
We pick a small, real first version we can ship in weeks, put it in front of users, and improve from what they actually say.
We work cloud-first and stay in close contact — several hours of daily overlap with UK and EU hours, fluent English, and a written scope so there are no surprises.
Why teams hire us
A small, senior team that ships working software and stays around to run it. Here's what working with us actually gets you.
We run what we build
We don't only take client work — we ship and operate our own live SaaS products. You're hiring a team that has to live with its own decisions in production.
A written scope and a real price
Before we write production code you get what we'll ship, when, and what it costs. If scope changes, we tell you what that costs before we do it.
Competitive offshore rates
Pakistan-based, so you get senior full-stack work at a fraction of UK or US agency rates — without dropping to junior quality.
Timezone overlap and clear English
Several hours of daily overlap with UK and EU working hours, and fluent English — close enough to feel like an in-house team.
We ship small and often
A short cycle from scope to a first useful version. You use it, we adjust. No quarter-long black boxes and no big-bang launch day.
No lock-in
You own the code, the data, and the infrastructure. We can keep running it, or hand it over clean and documented. Your call, not ours.
What we build on
Boring on purpose. We pick proven tools that a future developer can still maintain — mostly Ruby on Rails and PostgreSQL, with Flutter for mobile.
