What Cubbit does
Cubbit S.r.l. is a Bologna-based deep tech company founded in 2016 by four co-founders from the University of Bologna's Collegio Superiore, building a geo-distributed cloud object storage platform positioned as a European sovereign alternative to US hyperscalers. The core technology, branded DS3, uses a peer-to-peer architecture in which data is AES-256 encrypted, fragmented via proprietary Reed-Solomon erasure coding (n=20, k=40) on Galois field GF(256), and distributed across geographically dispersed nodes under a cryptographically blind Coordinator that cannot itself access user data, with an optional zero-knowledge mode for end-to-end client-side encryption. The platform claims 99.999999999% data durability, 99.95% availability, 3x storage overhead (vs. 3x replication on traditional systems), and full S3 API compatibility across bucket operations, Object Locking, versioning, and multipart upload.
The company monetizes through two delivery models: DS3 Cloud, a managed service delivered through partner-certified data centers on usage-based pricing, and DS3 Composer, a software-defined, self-hosted platform sold on annual subscription that allows enterprises and managed service providers to operate their own sovereign storage infrastructure. An add-on Cubbit Virtual NAS product bridges the platform into traditional NFS/SMB file sharing environments. Go-to-market combines direct enterprise field sales (defense, healthcare, aerospace, education, critical infrastructure) with an extensive European channel and technology partner network including WIIT, Worldstream, Ailanto, HERABIT, Rai Way, SUSE, Elemento Cloud, StorPool, and Commvault, plus 30+ S3-compatible integrations with backup, analytics, and data platform tools (Veeam, Rubrik, Cohesity, Snowflake, Databricks, Kafka, Cloudflare).
Cubbit reports 400+ enterprise customers across at least ten European countries, a team of 50-60 people, and approximately $25M in cumulative funding across seed (2021) and Series A (July 2024) rounds, with LocalGlobe and ETF Partners co-leading the Series A. The company is recognized by the European Commission as a Top 30 EU deep tech scaleup, holds ACN qualification from the Italian Agency for National Cybersecurity, and is certified across ISO 9001, 27001, 27017, 27018, 20000-1, and 22301, with explicit positioning around GDPR, NIS2, and DORA compliance. Pricing is quote-based and not publicly disclosed; stated value propositions include up to 80% cost savings versus hyperscalers, up to 50% lower IT resource consumption, and up to 5X ROI for partner service providers.

Cubbit product offering
Product offeringCore offering
Cubbit sells geo-distributed S3-compatible cloud object storage delivered as either a fully-managed service (DS3 Cloud) through partner data centers, or as a self-hosted software-defined platform (DS3 Composer) that enterprises and MSPs install on their own infrastructure. Both offerings encrypt, fragment, and geo-distribute data across multiple nodes using Reed-Solomon erasure coding for hyper-resilience and data sovereignty. The company also provides a Cubbit Virtual NAS VM image that exposes S3 buckets over NFS/SMB for traditional file-sharing environments.
Product overview
Cubbit offers a portfolio of geo-distributed cloud object storage products centered on its proprietary DS3 (Distributed Simple Storage Service) technology. The core offering consists of two distinct delivery models: DS3 Cloud is a fully-managed geo-redundant cloud object storage service offering instant access and up to 80% savings vs. hyperscalers, while DS3 Composer is a software-defined platform allowing enterprises and MSPs to deploy and manage their own sovereign, S3-compatible distributed storage in minutes. Both products share the underlying geo-distributed architecture that encrypts, fragments, and replicates data across geographically distributed nodes using Reed-Solomon erasure coding. An add-on Virtual NAS product extends the platform to traditional file sharing environments. All offerings provide S3 compatibility, AES-256 encryption, and compliance with GDPR, ISO 27001, and other regulatory frameworks.

Cubbit competitors and assessment
Company assessmentDirect peers
- Wasabi Technologies: Wasabi offers S3-compatible hot cloud storage with a flat, low-cost pricing model targeting the same displacement-from-AWS-S3 use case. Cubbit competes head-to-head on price-sensitive backup and archival workloads, though Cubbit adds a geo-distributed architecture and European sovereignty angle that Wasabi lacks.
- Backblaze: Backblaze B2 is an S3-compatible object storage service positioned on affordability versus AWS S3, targeting backup and archive workloads. Like Cubbit, it competes on cost economics and S3 compatibility, but Backblaze is US-based without Cubbit's European sovereignty or geo-distributed P2P differentiation.
- Storj: Storj is a decentralized cloud storage network using erasure coding across a distributed node operator network, the closest architectural analog to Cubbit's P2P geo-distributed approach. Both target S3-compatible APIs and decentralized durability, though Storj is more developer-focused while Cubbit emphasizes enterprise sovereign workloads.
- MinIO: MinIO provides S3-compatible object storage software deployable on-premises or in any cloud, often used as the storage layer for sovereign and private cloud deployments. Cubbit's DS3 Composer competes with MinIO in the software-defined sovereign S3 category, though Cubbit adds geo-distribution while MinIO relies on underlying infrastructure replication.
- Cloudian: Cloudian provides enterprise S3-compatible object storage appliances and software for on-premises and hybrid deployments, frequently used in sovereign and regulated workloads. Cubbit and Cloudian both serve backup, archive, and sovereign cloud use cases; Cloudian is more hardware-centric while Cubbit emphasizes geo-distributed software architecture.
Regional players
- Scaleway: Scaleway is a European cloud provider headquartered in France offering S3-compatible object storage (Scaleway Object Storage) under European jurisdiction. Both companies target the European sovereignty narrative against US hyperscalers, though Scaleway operates a traditional centralized cloud while Cubbit's P2P model is structurally different.
- OVHcloud: OVHcloud is a major European cloud provider with S3-compatible object storage and explicit sovereign cloud positioning. Both companies serve GDPR/sovereignty-driven European buyers; OVHcloud is much larger and broader in offering while Cubbit focuses narrowly on geo-distributed object storage with deeper technical differentiation in that niche.
- Hetzner: Hetzner is a German hosting and cloud provider offering S3-compatible storage (Hetzner Storage Box, Object Storage) at competitive European pricing. Both companies target cost-conscious European customers seeking alternatives to US hyperscalers, though Hetzner operates conventional centralized infrastructure.
Emerging players
- Filebase: Filebase is a S3-compatible object storage platform built on decentralized storage networks (IPFS, Sia), serving a similar developer and Web3-leaning audience. Both companies leverage decentralized architectures with S3 compatibility, though Filebase is earlier-stage and Web3-focused while Cubbit targets regulated enterprise and public-sector buyers.
Broad incumbents
- IBM Cloud Object Storage: IBM Cloud Object Storage is an enterprise S3-compatible object storage offering within IBM's broader hybrid cloud portfolio. Both companies target regulated and enterprise workloads with S3-compatible APIs and strong compliance credentials, though IBM is a broad incumbent with significantly larger scale and a centralized architecture versus Cubbit's geo-distributed model.
