Chocolate Cloud ApS

Chocolate Cloud ApS is a Danish deep-tech company based in Aarhus that develops software for secure, distributed data storage. According to its own materials, it is a high-tech start-up with deep MIT roots and a global perspective, backed by committed investors from Denmark and Germany and guided by a professional board of directors that has included the former CEO of Intel Mobile in Denmark, an MIT professor, and the 5G Lab Director of Germany. The company positions itself as an expert in distributed storage technology, advancing cloud storage through innovation and powering privacy-first software for global partners. At the core of Chocolate Cloud's technology is a combination of compression, encryption, redundancy, and distribution, built on years of applied research and real-world implementation. Its approach compresses data before adding redundancy, encrypts data at the source so that nothing unprotected leaves the user's device, offers adaptive redundancy through a flexible coding system, and supports custom data placement across clouds or on-premises servers. The company emphasizes compliance, location-aware storage, end-to-end encryption, and dynamic resilience that learns from traffic patterns to shift data fragments and adjust redundancy at scale. Chocolate Cloud delivers software products for efficient and privacy-preserving multi-cloud data storage, spanning hybrid clouds and multiple public and private clouds. It also offers technology to reduce storage in OpenStack object-based storage and Hadoop big-data environments. Its product line includes SkyFlok, a GDPR-compliant file storage and sharing platform aimed at small-to-medium businesses and enterprises, and SkyFlok Smart Storage, an S3-compatible object storage offering with location selection and redundancy customization that was under closed beta testing. The company has stated that it integrates over 15 cloud service providers and covers more than 100 locations worldwide. Since 2016, Chocolate Cloud has contributed to European research and innovation programs, from Horizon 2020 to Horizon Europe, working on cloud storage and privacy. In February 2018 it announced that it had become the first Scandinavian company to be white-listed for production in Intel SGX, an architecture extension that uses secure enclaves within the CPU. Chocolate Cloud uses Intel SGX in a secure key-value store solution for the cloud and in a premium tier of SkyFlok. The company's stated mission is to redefine the expected reliability, costs, speed, and privacy of cloud and internet services through its patented technology and world-class team.

Chocolate Cloud ApS is a Danish high-tech start-up based in Aarhus, described in its own materials as having deep MIT roots and a global perspective. It has attracted committed investors from Denmark and Germany and assembled a professional board of directors that has included the former CEO of Intel Mobile in Denmark, an MIT professor, and the 5G Lab Director of Germany. The company's leadership includes CEO and Chairman Daniel E. Lucani, who holds a PhD from MIT, is the author of eight patents and applications on network coding, and heads the Network Computing, Communication, and Storage (Net-X) Group at Aarhus University, and CTO and board member Marcell Fehér, who holds an MSc in software engineering and a PhD in data compression. From 2016 onward, Chocolate Cloud has contributed to ambitious European research and development initiatives, progressing from Horizon 2020 to Horizon Europe, with work focused on cloud storage and privacy. Its research activity has spanned multiple R&D projects, partners, person-months, and tasks led, including projects related to a sustainable and resilient Cloud-Edge-IoT (CEI) ecosystem and machine learning. A significant milestone came on February 19, 2018, when Chocolate Cloud announced that, after a year-long process, it had become the first Scandinavian company to be white-listed for production in Intel SGX. Intel SGX is an architecture extension designed to increase the security of application code and data by using secure enclaves within the CPU. Chocolate Cloud applied Intel SGX in two solutions: a secure key-value store for the cloud that uses enclaves within the Intel chip to guarantee that data is not only communicated securely to the cloud but also processed and stored with the highest level of confidentiality and privacy, developed as part of the H2020 SecureCloud Project supported by the European Commission; and a premium tier of its upcoming secure multi-cloud storage software, SkyFlok. Chocolate Cloud's product strategy centers on efficient and privacy-preserving multi-cloud data storage across hybrid clouds and multiple public and private clouds, along with technology to reduce storage in OpenStack object-based storage and Hadoop big-data environments. Its flagship offering, SkyFlok, is a privacy-first SaaS platform that helps businesses share and store files securely across user-selected storage locations, targeting small-to-medium businesses and enterprises with compliance features for GDPR, HIPAA, and GLBA. A second product, SkyFlok Smart Storage, is an S3-compatible object storage service with location selection and redundancy customization; it was under closed beta testing and not yet publicly available. The company has stated that it integrates over 15 cloud service providers and covers more than 100 locations worldwide, allowing users to distribute data fragments across providers and stay online during provider outages. The company's stated mission is to redefine the expected reliability, costs, speed, and privacy of cloud and internet services through patented technology and a world-class team. Its technology combines compression, encryption, redundancy, and distribution, with features such as compression built in before redundancy is added, encryption at the source, adaptive redundancy, custom data placement, compliance made easy, and dynamic resilience that learns from traffic patterns to shift data fragments and adjust redundancy at scale. Looking ahead, Chocolate Cloud has signaled expansion into edge and mobile storage for low-latency applications and a future-ready focus on 5G networks and IoT requirements.
