About 41Stack
41Stack is a Ruby on Rails development studio based in Pakistan. We build custom SaaS products, business automation, and integrations for clients in the UK, US, UAE, and beyond.
About
We're not just a contractor — we ship and run our own Rails SaaS products, Fbrly and Postory. That means when you hire us, you're hiring a team that knows how to build software and keep it running in production.
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 Rails team that ships. Here's what working with us actually gets you.
Deep Rails expertise
Rails is our main stack, not a side skill. We ship production Rails — including our own live SaaS products.
Competitive offshore rates
Pakistan-based, so you get senior full-stack work at a fraction of UK/US agency rates — without cutting quality.
Timezone overlap & English
Several hours of daily overlap with UK and EU working hours, and fluent English — so it feels like an in-house team.
We ship small and fast
A short cycle from scope to a first useful version. You use it, we adjust. No quarter-long black boxes.
What we build on
Boring on purpose. Mostly Ruby on Rails and PostgreSQL, with Flutter for mobile.
