Software that
just works.
A full-stack studio for custom software of every kind — with a specialist reputation for seamless integrations that make your systems talk to each other.
What we do
Generalist capability. Specialist reputation.
We build anything you need — and we're known for the hard part: making separate systems work as one.
Custom Software
Web apps, internal tools, custom systems — whatever your business actually needs, built properly.
Integrations
Connect any system to any other. E-commerce APIs, inventory, payments, third-party tools — talking seamlessly, in real time.
Inventory & Commerce
Proven expertise in the systems that run stores — stock, orders, fulfillment, and the webstores they power.
How we build
AI-accelerated
We put AI to work across the build to ship in days, not months — fast, but every output is reviewed and owned by senior engineers.
Senior-led, always
Every decision and every line is driven by senior engineers. You're never a training ground for juniors.
Efficient by design
A lean, globally distributed senior team means top-tier engineering without a top-tier agency price tag.

Hand us the goal. We'll bring back a working product — and the decisions we made to get there.
Featured project
A full inventory system, rebuilt and wired to the webstore.
We rebuilt the entire inventory platform for UK Hip Flasks from the ground up and wired it directly into their webstore APIs, so stock, pricing, and orders sync in real time. Delivered on time, and stable in production from day one.
Entire inventory system, from scratch.
Live sync with webstore APIs.
Stable from day one.
“Having worked with Altos for a few months, I'd happily recommend them to any business looking for a programmer. The replacement system they built for my business is a great improvement on previous versions: faster, cleaner, and it just works better overall. Once tasks were agreed, they worked independently and got on with the job, often suggesting improvements along the way. I've found them reliable and responsive.”

FAQ
Questions, answered.
What does Altos do?
Altos is a full-stack software studio. We build custom software of all kinds — web apps, internal tools, and complete systems — and we specialize in integrations that connect your existing tools so they work as one.
What integrations does Altos specialize in?
We connect e-commerce and webstore APIs, inventory systems, payment providers, and third-party tools. If a system has an API, we can wire it into the rest of your stack and keep data flowing in real time.
Which platforms and systems can Altos integrate?
Common ones include Alibaba, Etsy, freewebstore, Shopify, and WooCommerce, plus inventory and order-management systems. Because we build to each API, we can integrate virtually any platform that exposes one.
How fast can Altos deliver?
We're AI-accelerated and senior-led, so we typically ship in days or weeks rather than months — without cutting corners. Every output is reviewed and owned by senior engineers.
Is Altos expensive?
No. A lean, globally distributed senior team lets us deliver top-tier engineering without a top-tier agency price tag — premium quality at a fair, efficient rate.
