About the company

Cirrus Data Solutions provides data mobility technology to migrate block storage across on-prem, cloud, or hybrid environments with zero downtime. Its TDI technology enables live migrations from any vendor to any destination, including hypervisor migrations, via Cirrus Migrate On-Premises and Cirrus Migrate Cloud (mobility-as-a-service). The company distinguishes itself through seamless, real-time, any-to-any migrations without disrupting production, backed by thousands of migrations totaling over an exabyte of data, distributed through a channel network with partners like Dell, HPE, IBM, and Pure Storage. Its goal is to help large organizations modernize storage, consolidate data centers, and speed cloud adoption by automating complex migration projects.

Simplify's Take

What believers are saying

  • October 23, 2025 MCP Server turns AI agents into migration operators.
  • September 16, 2025 VergeIO partnership targets VMware displacement demand directly.
  • January 14, 2025 OpenShift integration broadens access to Red Hat modernization projects.

What critics are saying

  • VCBacked lists January 2022 last funding, constraining scale against better-funded rivals.
  • VergeIO and Red Hat reduce Cirrus differentiation by bundling migration into platforms.
  • Channel dependence creates existential risk if Dell, HPE, or AWS prioritize substitutes.

What makes Cirrus Data Solutions unique

  • Patented TDI enables live block migration without downtime across any storage vendor.
  • Cirrus Migrate Cloud spans VMware, Hyper-V, AHV, and OpenShift Virtualization migrations.
  • Channel partnerships with Dell, HPE, IBM, AWS, and Microsoft widen enterprise reach.
