A Lostium maker at work

We design and develop the digital product your business needs.

From consultancy to production, with AI applied for real. We take it where others can’t.

We don’t just sell technology, we solve challenges.

Where others can't reach

“I have an ambitious idea and no one knows how to execute it.”

We turn it into a real product, step by step.

“My platform has outgrown itself.”

We grow it or rebuild it without stalling your business.

“I want to use AI in my business, but no hype.”

We integrate it only where it adds value and you can make the most of it.

“I need a critical product that can’t fail.”

Large-scale, international and demanding projects. That’s our thing.

Frequently asked questions

Do you work with companies of any sector and size?

Yes. We have 25+ years across very different sectors, from startups to large organisations and public institutions.

How long does a project take?

It depends on the scope, but we prioritise reaching a working MVP early: weeks, not quarters.

Can you integrate with my team?

Yes. We work as technical direction, a mixed team or turnkey, whatever you need.

Who owns the code?

The code is yours and you can use it to run your business. The intellectual property remains ours; if you want a development to resell to third parties, it requires a specific agreement and licence with us.

Is AI safe with my data?

It can be: we work with privacy by design and the option of self-hosting.

Do you only do development or consultancy too?

Both. Consultancy, direction, design, development and production.
