Business Overview
Backblaze provides cloud-based storage services, primarily targeting businesses with scalable data needs. Its two major segments are B2 Cloud Storage, a high-growth infrastructure-as-a-service (IaaS) platform for enterprise and AI workloads, and Computer Backup, a legacy recurring-revenue business. The company monetizes via consumption-based and committed contracts, increasingly emphasizing upmarket, multi-year agreements with large customers and AI infrastructure providers.
Performance Analysis
Backblaze’s Q2 results reflect a decisive shift upmarket, with revenue up 18% year-over-year and B2 Cloud Storage growth accelerating to 34%, its highest rate in seven quarters. The CoreWeave contract—a $335 million multi-year deal—drove a 67% year-over-year surge in ARR from customers contributing more than $50,000 annually, now totaling 235 accounts. This cohort’s expansion signals Backblaze’s successful transition from self-serve SMB to enterprise-grade provider.
Margin expansion was pronounced, with adjusted EBITDA margin reaching 30%, up 1,200 basis points year-over-year, and gross margin holding at 63% despite higher infrastructure costs. Operating leverage improved, with operating expenses rising just 6% against robust revenue growth. Free cash flow margin climbed to 8%, supporting ongoing investment in capacity to meet contracted demand through 2027.
- Contracted Revenue Visibility: RPO (remaining performance obligations) increased by $320 million, led by CoreWeave, providing multi-year revenue clarity.
- Price Increase Execution: B2’s May price hike contributed 8 percentage points to growth with minimal churn, demonstrating strong customer stickiness.
- Legacy Stabilization: Computer Backup declined just 2% year-over-year, outperforming expectations as churn initiatives and targeted acquisition offset structural headwinds.
Backblaze’s ability to secure larger, longer-term AI and enterprise contracts is fundamentally changing its revenue profile and positioning the company for sustained growth and margin improvement.

Strategic Positioning
1. AI Infrastructure as a Growth Engine
Backblaze is now a core storage provider for AI clouds and neoclouds, with the CoreWeave deal serving as a high-visibility proof point. The company estimates a $14 billion market opportunity for capacity tier storage in AI infrastructure by 2031. AI-native firms and leading model developers increasingly require scalable, affordable, and performant storage, all areas where Backblaze’s hard drive-based platform excels.
2. Managed Storage Model Unlocks Capital Efficiency
The managed storage approach—where Backblaze operates its software on customer-owned hardware—reduces CapEx needs, enabling service expansion into regional and sovereign data centers. This capital-light model is particularly attractive for large, sophisticated AI customers and is already generating interest beyond CoreWeave, with several active pipeline discussions.
3. Upmarket and Multi-Year Contract Traction
Enterprise and AI customers are driving a shift toward longer-duration, higher-value contracts, with four deals over $500,000 this quarter and 57% growth in the $50,000-plus ARR cohort. This not only increases revenue visibility but also embeds Backblaze deeper into mission-critical customer workflows, reducing churn risk and supporting margin expansion.
4. Developer and AI Agent Platform Investments
Backblaze is positioning itself as the default storage layer for AI builders, launching SDKs for TypeScript and generative media, and running hackathons to drive adoption among developer communities. These efforts are designed to capture early-stage AI companies that could scale into large enterprise accounts over time.
5. Operating Leverage and Cash Flow Discipline
Disciplined cost management and operating leverage are translating to improved cash flow, even as CapEx ramps to support future demand. The company’s ability to maintain positive free cash flow and secure $150 million in available lease lines provides flexibility to scale without diluting shareholders.
Key Considerations
This quarter marks a strategic inflection for Backblaze, as it pivots from SMB-centric self-service to enterprise-grade, AI-driven infrastructure provider. The combination of upmarket wins, capital-light managed services, and developer platform investments is reshaping its growth trajectory.
Key Considerations:
- AI Storage Validation: CoreWeave’s selection signals Backblaze’s credibility for hyperscale AI workloads.
- Contracted Revenue Base: Multi-year commitments from large customers underpin revenue and margin visibility through 2027.
- Capital-Light Opportunity: Managed storage model could structurally improve margins and reduce CapEx intensity.
- Go-to-Market Transformation: New CRO and leadership are accelerating upmarket sales and pipeline repeatability.
- Legacy Headwinds Managed: Computer Backup remains a declining but cash-generating segment, funding growth initiatives.
Risks
Backblaze faces execution risk as it scales up enterprise and AI-focused operations, including the need to deliver on large, complex contracts without margin slippage. CapEx requirements are rising to meet contracted demand, and while the managed storage model mitigates some capital intensity, hardware price volatility and ramp timing could pressure near-term margins. Competitive threats from hyperscale clouds and alternative storage providers remain acute, especially as AI infrastructure needs evolve rapidly.
Forward Outlook
For Q3 2026, Backblaze guided to:
- Revenue of $44.4 million to $44.8 million
- Adjusted EBITDA margin of 27% to 29%
For full-year 2026, management raised guidance to:
- Revenue of $172 million to $174 million (up from $161.5 million to $163.5 million)
- Adjusted EBITDA margin of 27% to 29% (up from 23% to 25%)
Management highlighted:
- Greater visibility from multi-year contracted demand, especially from CoreWeave and other large deals
- Exclusion of usage above minimums and potential large deals from guidance, signaling potential upside if pipeline closes
Takeaways
Backblaze’s Q2 results crystallize its transition into an enterprise AI infrastructure player, underpinned by large, multi-year contracts and a capital-light managed storage model. Investors should track the pace of managed storage adoption, margin durability as CapEx ramps, and the company’s ability to convert pipeline into additional multi-year, upmarket wins.
