Key Benefits

For forward thinking Busineses

We embrace businesses who think forward. Whether you care about the environment, vendor lock, data souvereignty, or a combination of these, we are here to help you succeed.

Help, not Hurt

We believe cloud computing should benefit the planet, not harm it. Our servers provide computing power for cloud and useful heat for nursing homes, apartments and pools. By turning waste heat into warm showers, we create a win-win solution that allows cloud infrastructure to grow sustainably, without the traditional carbon footprint and water waste of data centers.

Smarter Cloud Infrastructure 

Forget massive, energy-draining data centers. Instead, our servers are strategically placed in existing urban buildings like care homes, hotels, and pools. This distributed setup cuts waste and eliminates the need to build new data centers. 

null

Double Impact 

We use green energy. Twice. Once to power our servers and again by repurposing the heat they generate. Instead of wasting energy cooling servers, we put that heat to work warming water for the building. It’s good for the planet and the community. For every kilowatt of power used, we can cut CO₂ emissions equivalent to taking about 1.4 cars off the road each year.

Open and Flexible 

Leafcloud is built on open-source technology, which means no vendor lock-ins and total flexibility. Whether you need AI/ML pipelines, virtual servers, or managed Kubernetes, we’ve got you covered with tools that work seamlessly across multi-cloud setups.

European Data Security  

Leafcloud' servers are housed in The Netherlands in compliance with with European data and privacy regulations. We safeguard personal data in compliance with the GDPR, and maintain ISO 27001 & SOC2 type II certifications through regular audits.

Real Change

Incremental improvements aren’t enough. Leafcloud is about rethinking how the cloud works, leading the way with sustainable tech and rewriting the future of digital infrastructure.
