Overview

Founded in Bologna in 2016 by Stefano Onofri, Alessandro Cillario, Marco Moschettini and Lorenzo Posani, Cubbit develops distributed storage technology. DS3 Composer orchestrates encrypted, fragmented data across storage infrastructure and locations chosen by operators, providing S3-compatible services that can be sold under a provider's brand or operated privately by an enterprise. Cubbit also offers hosted DS3 Cloud.

Its historical funding includes a €7M mixed financing package announced in July 2021 (€3.5M equity, €2.4M convertible notes, €1.1M debt), and a $12.5M venture round announced on 16 July 2024, co-led by LocalGlobe and ETF Partners. The company says it has raised $25M overall and serves more than 400 organisations; these are company-reported figures with no independently reconciled equity-only total.

Worldstream announced on 11 March 2026 that it was using DS3 Composer across three Dutch data centres, initially 1 PB.

Why Cubbit is interesting

Cubbit moved from consumer peer-to-peer storage to DS3 Composer, software that lets enterprises and service providers run their own geographically distributed S3-compatible storage. A $12.5M July 2024 investment led by LocalGlobe and ETF Partners supported its European expansion. Named partnerships including Worldstream in the Netherlands show its reseller-led route to market, while actual revenues, margins and contract deployments require independent diligence.

Product & use cases

DS3 Composer is enterprise software for orchestrating encrypted, fragmented S3-compatible object storage across operator-selected infrastructure and geographic locations. Cubbit also offers DS3 Cloud hosted S3 storage; this is not an AWS/Azure-equivalent full computing cloud.

  • MSPs, hosting and telecom operators offering white-label or sovereign S3-compatible storage.
  • Enterprise backup and recovery, including integrations with Veeam and Commvault.
  • Long-term archiving and large-scale object storage for regulated and data-intensive organisations.
  • Hybrid/on-premises geographic resilience with jurisdiction-specific data placement.

Key facts

  • July 2024: raised $12.5M, led by LocalGlobe and ETF Partners; stage not specified in original announcement.
  • July 2021: €7M financing package comprised €3.5M equity, €2.4M convertible notes and €1.1M debt; do not mislabel all €7M as priced equity.
  • March 2026: Worldstream partnership across three Netherlands data centres, initially 1 PB; capacity is not evidence of paid storage utilisation.
  • Company reports $25M overall raised and 400+ organisations served; independent verification and funding-component reconciliation remain open.

Competitive landscape

Edge: Claims programmable geographic distribution, control of data placement and a software-enabler model that uses a customer's or partner's infrastructure. Relative TCO, performance, resilience, S3 API coverage, legal sovereignty and security assurances vary by deployment and must be validated rather than accepted from marketing claims.

The meaningful peer group includes enterprise object-storage software and operational self-hosting alternatives, not generic consumer file-sharing services. Evaluate effective cost per usable TB, erasure coding overhead, S3 feature coverage, region/failure-domain independence, Object Lock behaviour, vendor support, recovery objectives, independent audits and exit procedures. EU location alone does not demonstrate legal or operational sovereignty.

  • Cloudian direct

    Commercial S3-compatible object-storage software/platforms.

  • Scality direct

    Commercial enterprise and service-provider object storage.

  • Ceph alternative

    Open-source distributed storage operated and supported by infrastructure teams.

  • MinIO alternative

    S3-compatible software deployment alternative; licensing/enterprise-support scope should be checked.

  • Backblaze B2 adjacent

    Managed S3-compatible storage service rather than the same white-label software model.
