You bring the vision.
We engineer it.
Engineered around your first product
An engineering studio for digital products, the backend and cloud platforms behind them, and AI that runs in production.
Teams we have worked with
Most software is easy to start and hard to keep running. We build the kind your team can still change in five years.
- Ideas need a working product.
- Products need a platform that holds.
- We build both, as one team.
01What we do
What we build
Five areas of work. Most projects need two or three of them working together, from the first prototype to the system running in production.
AI and intelligent systems
Agents, retrieval, and machine learning connected to real workflows, with review points and evaluations.
See how we do itProduct design and engineering
Web and mobile products from discovery and prototype to release, with design systems your team can extend.
See how we do itBackend and platforms
Services and APIs in Rust, Go, Java, and Node.js, and modernisation of the systems everything else depends on.
See how we do itData and machine learning
Pipelines, PostgreSQL and Kafka, vector stores, and the models trained and served on top of them.
See how we do itCloud and Kubernetes
Infrastructure on AWS, GCP, and Azure, containers on Kubernetes, and the monitoring to run it calmly.

How it gets built
Interface, services, data, models, and infrastructure, built by one team in five stages. Scroll to watch the system come together.
01 / 05Define
A line.
Every project starts as one sentence: the outcome, who it is for, and what must not break. We agree it before anything is drawn.
02 / 05Design
A blueprint.
The architecture, data model, and user journeys are sketched together: which services, which stores, and where AI earns its place.
03 / 05Build
A working system.
Services in Rust, Go, Java, or Node.js, the APIs, the interface, and any models run end to end early, in your repositories.
04 / 05Release
A release.
Containers roll out on Kubernetes in stages, behind CI checks and canaries, with a clear way back if something looks wrong.
05 / 05Operate
A running platform.
Metrics, traces, and alerts cover every service and model, with runbooks. Your team runs it, or we keep running it together.
04Why Sozeno
Why teams work with us
We start with the outcome and the people who will own it. The stack, the architecture, and the AI follow from that.
- 01
No black boxes.
You see working software every week, and the code lives in your repositories from the first day.
- 02
Code your team can own.
Readable, tested, and documented, so your engineers can take it over without a rewrite.
- 03
Built for the day after launch.
Monitoring, runbooks, and a handover plan are part of the work, not an extra.
- 04
One team, one conversation.
The people who scope the work are the people who build it, so nothing is lost in a handover.
05Engagement models
Ways to work together
Four ways to start, from a defined first step to ongoing support. Each says when it fits, what you get, and who is on the team.
Sozeno Your team
Defined scope
Discovery sprint
Good when You have an idea or a problem, and need a clear plan before committing budget to a build.
A small Sozeno team works beside your decision makers.
- Product brief
- Clickable prototype
- Architecture outline
- Delivery plan you can fund
Defined outcome
Build sprint
Good when You know what to build and need a team to ship a working first version, then harden it for production.
Sozeno builds; your product owner steers.
- Working first release
- Weekly demos
- Tests and CI
- Production hardening
Ongoing capacity
Embedded delivery
Good when Your roadmap is clear but your team is stretched, and hiring would take too long.
Sozeno people work inside your team, as part of it.
- Engineers in your team
- Your tools and rituals
- Shared code ownership
- Flexible scale
Ongoing partnership
Reliability support
Good when You run a live platform and want it to stay healthy, secure, and easy to change as it grows.
A small Sozeno team keeps watch around your running system.
- Monitoring and alerts
- Incident triage
- Upgrades and patching
- Platform health reviews
