About

One partner instead of three.

Zealient is an innovation and cloud computing partner for small and medium businesses.

Getting a product built usually means hiring an agency for the app, a DevOps contractor for the hosting, and an AI consultant for anything smart. Each one hands off to the next, and the business owner is left to hold it together.

Zealient does all three as one team. We build your web and mobile apps, run and scale them on secure AWS infrastructure, automate the repetitive work, and add AI where it solves a real problem. You get one conversation, one plan and one team responsible for the result.

We keep things practical: the simplest setup that does the job, running costs you can see, and security built in from the first release.

How we think

What you can expect from us.

One team, one conversation

The people who build your app also run it and add the AI. Nothing gets lost between an agency, a DevOps contractor and an AI consultant.

Sized for SMEs

We pick the simplest setup that does the job and keep running costs visible, so you pay for what your business needs now.

Secure by default

Private networks, encrypted data, least-privilege access and backups are part of the first version, not a later project.

Built to be handed over

Infrastructure is written as code and the work is documented, so you are never locked in to us.
