At Kleis, we don’t just talk digital strategy. We build it with you. Our approach is simple: pinpoint what drives the most value, implement it alongside your teams, and continuously enhance their skills throughout the journey.

Transform
Strategic Roadmaps, due diligences, and technical and methodological audits: gain a clear, actionable understanding of your IT ecosystem. We move seamlessly from strategic discussions with decision-makers to in-depth technical analyses, providing the insights needed to guide decisions at every level.

Build
From design to implementation, we operate as true Product Engineers, able to drive both the vision and the delivery. We work closely with business teams, with one clear objective: delivering what creates the greatest value.

Learn
We train your teams in the practices and technologies that make a real difference: cloud and containerisation, modern development, coding best practices, AI, and ML.

It is a team that works hard to ensure the work is finished on time, and the quality and efficiency of delivery is exceptional.
Whether it be a bigger picture review or a review of a pull request – the Kleis team makes it happen.
From the Alpian team to the Kleis team: thank you.
The Kleis team is simply exceptional. We were brought together by a clever mind who saw how we complemented each other, and he was right! We have truly built something together, not just a technical artefact – which is excellent, by the way – but also a culture and a team. The work is fluid, efficient, and of high quality. In software, they say you can't have quality and meet deadlines. With Kleis, you can!
Kleis Technology has been an exceptional partner over the past four years.
Their unique blend of digital expertise, business acumen, and team-coaching mindset was pivotal in shaping and delivering eQosphere.
Thanks to their support, we built high-quality, efficient, and market-oriented software that empowers manufacturers to turn state-of-the-art LCA data into actionable climate roadmaps.
I wanted to say thank you for the quality of the training you have given us these past two days.
This training was as helpful for "newbies" like me as for more experienced people. Additionally, you have been extremely patient during the exercices. And the subjects were fascinating.
To sum it up, the quality of the training was perfect perimeter-wise, and the quality of the trainers as well.
