AI-Native Software Engineering

Ideas to working software in weeks, not months

We are senior engineers who work AI-first in everything we do. We learn your business, shape the solution with you and deliver it faster than any traditional team can.

Talk to us See how we work

AI makes senior engineers 10x faster. We exclusively employ senior engineers.

We build everything AI-first: analysis, design, code, tests and operations. In the hands of a senior engineer, that turns weeks of work into days.

That changes how projects run. A small squad of our engineers delivers 10x, often 100x, more than a traditional team. No project managers relaying messages, no hand-offs, no junior teams learning on your budget.

Writing code is no longer the hard part. Engineering maintainable, scalable, secure, usable and delightful software still is.

AI can produce code all day, and the industry is shipping more of it than ever while quality falls. The hard part is knowing what to build, how it fits your business and how to keep it solid as it grows.

That’s the layer we work on. Clean architecture, automated tests and sound design keep your software fast to change, not just fast to build. We learn your domain and stand behind what we deliver, as we have since 2015.

What we
deliver

Four kinds of work, one way of doing it: senior engineers, AI-first, close to your business.

Custom business software

New products and applications for web, mobile, desktop or distributed systems. You get a first working version in one to two weeks, then we evolve it with you.

Process automation

Your teams lose hours to manual steps, spreadsheets and copy-paste between systems. We map how work actually flows and automate the friction away, so your people can focus on the work only they can do.

Modernization and migrations

Legacy rewrites used to take years. AI-native engineering does them in weeks or months. We modernize what holds you back while your business keeps running.

AI in your product and operations

We build AI features, agents and integrations into your software and workflows. They are designed around your data and processes and engineered to run reliably in production.

Already have a project running, or one in trouble? We step in at any stage. Once it’s live, we stay: we run, support and evolve what we build for as long as you need.

How we
work

No thick specification up front. You see working software early and steer it as it grows.

1 2 3 4

  1. We learn your business.

    We start on-site with your domain experts to learn how your business really works and where the real problem is.

  2. Working software in one to two weeks.

    Instead of a long spec, you get a first version you can use hands-on.

  3. We evolve it with you.

    Short iterations, driven by your feedback. When your business changes, the software changes with it.

  4. We automate, run and improve.

    We automate the processes around it, keep it running and keep making it better.

Speed without the debt

AI lets anyone generate code. Keeping it clean is another matter. Across the industry, more code ships with less scrutiny, and reliability is slipping. We built our way of working to avoid exactly that.

Senior only.
Every engineer has deep computer-science fundamentals and experience across several stacks. They direct the AI; the AI doesn’t direct them.
AI-native, end to end.
Analysis, architecture, design, implementation, QA and operations all run on AI-powered workflows.
Discipline built in.
Clean architecture, proven design principles and automated testing keep your software growing without hidden technical debt.
Autonomous and transparent.
There is no management layer. Engineers own the outcome and keep their work visible, so you always know what’s happening and why.
Fits your team.
We integrate at any level, remote or on-site, in your stack and your processes.

Ways to work
with us

A dedicated squad

One or more senior engineers own your problem end to end, working directly with your domain experts.

Seniors in your team

Our engineers join your existing team and bring AI-native ways of working with them. Not extra hands, but people who take ownership.

A fixed scope

A defined result at a fixed price.

Fixed price, time & materials, or a mix of both, by project or by phase.

What we
stand for

AI changed how we work. It didn’t change what we value.

Reliability and proactivity

We deliver what we promise and are clear about what we can’t do. Moving fast means problems surface sooner, and we raise them early so you can course-correct on the fly.

Openness and transparency

Long partnerships are built on trust. We communicate often and openly, make our work visible as it happens and keep our costs clear.

Pragmatism and flexibility

We’re pragmatists. When your business changes, we change with it: technically, organisationally or contractually. AI-native delivery makes that change faster than ever.

Their markedly deep know-how and high flexibility make InfiniSwiss the perfect partner for Houzy. Even under high pressure and constant change the team always delivered highest quality results.
Florian Ruegg
CTO, Houzy AG
The app has allowed us to provide our sales representatives with an efficient and easy-to-use order entry tool for customers. The tool helped us to dematerialize the process completely so that the sales representative could spend as little time as possible on order processing and more time to dedicate on customer relations.
Daniel Pircher
Corporate Engineering, Dr. Schär
We work with Infiniswiss because their people have been carefully selected and integrate seamlessly into our team. The daily work, except for the physical separation, is no different from our local staff.

Frequently asked questions

Anything else? Ask us below.

How does a collaboration start?

Get in touch below and we’ll meet you, ideally in person in Switzerland or Romania. We learn your business and where software can help, then propose a first step you can see working within one to two weeks. Our advice is always free; we only charge for delivered value.

What does “AI-native” mean for my project?

AI is part of every step of how we work: requirements, design, code, tests, documentation and operations. Our senior engineers direct the work and own the result. For you, that means more done, sooner.

Isn’t AI-generated code risky?

It is without the right engineers. Code is cheap now; judgment isn’t. Our seniors own architecture, testing and quality, so you get software you can build on, not a pile of generated code.

How can such small teams deliver so much?

AI makes senior engineers 10x faster, and seniors don’t need managing. Without layers of coordination, a few people who understand your business move faster than a large team ever could.

What contract models do you offer?

Fixed price, time & materials, or anything in between. You can mix models by project, phase or team.

Do you work on-site or remote?

Usually both. We kick off on-site to learn your business quickly, then continue remotely, on-site or a mix of the two.

Can you join a project that’s already running?

Yes. We step in at any stage, including projects that are stuck or in trouble, and get them moving again.

Do you partner on new products?

Yes. If you have an idea and want an engineering partner rather than a vendor, let us know. We’re always fair, and we’ll assess its feasibility with you and challenge it from other angles too.

What happens after launch?

We stay as long as you need. We run, support and evolve what we build.
