Small Team.
Senior Talent.
We're not a 200-person factory. We're a focused team of experienced developers and designers building trading interfaces, SaaS platforms, mobile apps and websites — with the kind of attention larger agencies can't give.
Why We Started AppStackX.
We started AppStackX because we saw the same problem everywhere: businesses were paying agency prices for junior-level work, getting bloated software nobody could maintain, and dealing with agencies who disappeared after launch. We wanted to be different — a software house that builds things properly, whether that's a real-time trading interface, a SaaS platform, a mobile app or a website.
We built AppStackX as a place where the people you talk to are the same people who design and build your product. Where every project gets senior-level attention. Where the work we deliver is something we'd be proud to put our name on.
Our career background is in systems that aren't allowed to break — the team's past employers include PIMCO, S&P Global and JP Morgan — and we bring that same discipline to everything we build, from trading dashboards to product websites. We're small by choice, because at our size we can guarantee that your project won't be handed off to a team of juniors the moment the contract is signed.
We work remote-first with clients in the UK and internationally. You get a direct line to the people actually designing and building your product — no account managers relaying messages, wherever you happen to be.
Remote-First
UK & worldwide clients
Our Values.
Craft Over Speed
We'd rather ship one thing that works brilliantly than ten things that half-work. Every line of code is written with care, tested thoroughly, and documented properly.
Radical Honesty
If something isn't the right approach, we'll tell you — even if it means a smaller project for us. Trust is built on honesty, not on telling clients what they want to hear.
Long-Term Thinking
We build software that your future team can maintain. Clean architecture, sensible patterns, and documentation that actually helps — because we think about what happens after handover.
