Book a Sprint

Four offerings. All of them end in something shipped.

Appex designs and builds AI systems and custom software for companies that need the result running in production — not summarised in a slide deck.

AI Product Development

Custom Software Development

Custom Software Development

You have an idea for an AI product, or a feature that has to become one. We take it from technical feasibility to a version real users can break.


What you get

  • A feasibility assessment that tells you what is actually buildable today
  • Proof of concept, then an MVP with a real user in front of it
  • Full-cycle development — architecture, build, deployment, iteration
  • Technical leadership for AI R&D, if your team needs someone senior in the room


Choose this when you are building something new and the technical risk is the reason it hasn't started yet.

Custom Software Development

Custom Software Development

Custom Software Development

Web and mobile applications, and the systems behind them. We have built consumer apps used at national scale and internal platforms that had to keep working while the business changed around them.


What you get

  • Mobile applications for iOS and Android, and the backends that serve them
  • Web platforms and internal systems built to a documented architecture
  • Integration with the systems you already run, rather than around them
  • Deployment, monitoring and handover — the parts most projects skip


Choose this when you know what needs to be built and you need it built properly, the first time.

AI & Tech Advisory

B2B AI Video Generation

B2B AI Video Generation

Sometimes the expensive mistake is architectural, and it is made in the first month. We work as the technical partner who has to be right, not the vendor who has to sell you a build.


What you get

  • An AI readiness assessment — including where AI is the wrong tool
  • Technology and model selection, with the cost and lock-in trade-offs written down
  • Target architecture your own engineers can build against
  • A roadmap you can take to a board and defend line by line


Choose this when the decision is bigger than the project, and getting it wrong is expensive for years.

B2B AI Video Generation

Your compliance documentation, onboarding material and sales training, converted into localized video modules in 20+ languages — integrated into the LMS your people already use, and governed by your data policy rather than a vendor's.

Not sure which one you need?

That is what the AI Validation Sprint is for. Two weeks, fixed price, and a recommendation at the end — including, sometimes, the recommendation not to build.
