Backblaze (BLZE) Q4 2023: B2 Cloud Storage Grows 47% as Open Cloud Strategy Drives Margin Expansion
Backblaze’s Q4 marked a pivotal profitability milestone, with B2 Cloud Storage’s 47% growth and disciplined cost management driving adjusted EBITDA positive for the first time as a public company. The company’s open cloud positioning and channel expansion are unlocking larger deals and new enterprise use cases, while gross margin improvement signals durable pricing power. Management’s guidance and upmarket momentum suggest a structurally stronger business model heading into 2024.
Summary
- Open Cloud Value Proposition: Backblaze’s interoperability and transparent pricing are winning share from legacy cloud providers.
- Upmarket Channel Gains: Larger enterprise wins and new channel programs are accelerating deal size and customer mix shift.
- Margin Expansion Momentum: Pricing actions and operational leverage are structurally improving profitability profile.
Business Overview
Backblaze provides cloud-based storage and backup services, monetizing via recurring subscriptions across two primary segments: B2 Cloud Storage, object storage for businesses and developers, and Computer Backup, endpoint backup for consumers and SMBs. Revenue is generated through direct, channel, and partner sales, with a growing focus on enterprise and upmarket customers seeking alternatives to traditional hyperscalers.
Performance Analysis
Backblaze delivered a step-change quarter, with total revenue up 25% year over year. The standout was B2 Cloud Storage, which surged 47% and now comprises nearly half of total revenue, reflecting strong traction in enterprise and media verticals. Computer Backup, the legacy business, grew 10%, benefiting from price adjustments and stable retention.
Gross margin expanded to 77%, up roughly 300 basis points sequentially, as pricing changes and higher data center utilization drove leverage. The company achieved adjusted EBITDA profitability for the first time since going public, with positive $1.6 million on disciplined expense control and lower churn than anticipated. Cash usage fell sharply, down over 70% sequentially, supporting a robust liquidity outlook.
- Segment Mix Shift: B2 Cloud Storage’s outperformance is shifting the revenue base toward higher-value, stickier enterprise relationships.
- Retention Resilience: Gross customer retention remained strong at 91%, with only modest 1-2% data and license reductions despite price hikes.
- Operating Leverage: Revenue growth outpaced expense growth, driving positive EBITDA and sharply lower cash burn.
Net revenue retention (NRR) improved to 109% company-wide, with B2 Cloud Storage at 122%, underscoring the business’s ability to expand wallet share within its install base. This dynamic, coupled with a narrowing of guidance ranges, reflects growing confidence in both top-line growth and profitability for 2024.
Executive Commentary
"We are very pleased with our Q4 results. We delivered new product features and accelerated revenue growth, with B2 Cloud Storage having particularly strong growth of 47% year-over-year. We also demonstrated continued financial strength as we reached adjusted EBITDA profitability for the first time as a public company, and dramatically reduced cash usage."
Gleb Budman, Co-founder, CEO, and Chairperson of the Board
"Adjusted gross margin increased about 300 basis points sequentially to 77%, which was primarily due to the price increase across our products and, to a lesser extent, the higher utilization of prior data center expansions. This quarter adjusted EBITDA was a positive 1.6 million or 6% of revenue and beat the high end of our prior guidance of 3%."
Frank Patchell, Chief Financial Officer
Strategic Positioning
1. Open Cloud Ecosystem Leadership
Backblaze is positioning itself as a champion of the “open cloud,” emphasizing interoperability, affordability, and the elimination of restrictive egress fees that lock customers into legacy platforms. The company’s commitment to free egress and seamless integration with CDN and compute partners is drawing enterprise customers frustrated with traditional hyperscaler pricing and complexity.
2. Upmarket Expansion and Channel Leverage
The company is successfully moving upmarket, landing larger deals (such as a six-figure NFL team win) and expanding its Powered by Backblaze program for partners. Channel investments and consultative sales are unlocking new verticals, particularly in media, entertainment, and application storage, where workflow complexity and data volumes are rising.
3. Product Innovation and AI-Readiness
Product velocity remains high, with recent launches like ShardStash (enabling 30% faster uploads than Amazon S3) and Enterprise Control for backup customers. AI-related workflows are an emerging growth vector, as Backblaze’s storage platform supports cost-effective, large-scale data retention and integration with GPU compute partners. Leadership changes, including a new Chief Product Officer and a pending SVP of Sales, signal further focus on innovation and enterprise go-to-market.
4. Pricing Power and Margin Expansion
Recent price increases have stuck with minimal churn, validating Backblaze’s differentiated value proposition. Management expects gross margin to remain in the upper 70% range for 2024, with roughly half of the improvement attributed to pricing actions and the rest to operational efficiencies and improved data center utilization.
5. Disciplined Capital Allocation
CapEx and lease obligations are being tightly managed, with equipment spend flat to slightly down as pandemic-era buffers are utilized and lease run-off outpaces new commitments. The company expects to exit 2024 with at least $20 million in cash, supporting strategic flexibility even as it invests in sales and product innovation.
Key Considerations
Backblaze’s Q4 demonstrates a business model in transition, with strategic focus shifting from SMB/consumer backup to enterprise-grade, open cloud storage solutions. Investors should monitor the durability and scalability of this transition, as well as the company’s ability to sustain margin gains and upmarket momentum.
Key Considerations:
- Enterprise Customer Mix Shift: Larger deal flow and committed contracts are increasing average customer value and stickiness but may introduce longer sales cycles and more complex support needs.
- Channel and Partner Ecosystem: Expansion into channel-driven distribution and “Powered by Backblaze” partnerships is unlocking new growth vectors, particularly in media and AI-driven verticals.
- Pricing Sustainability: The ability to maintain low churn and high retention post-price increase will be a key indicator of competitive moat and pricing power.
- AI and Workflow Integration: Backblaze is well positioned as a “picks and shovels” provider for the AI age, but execution on product roadmap and ecosystem integration will determine if this becomes a material growth driver.
Risks
Key risks include competitive response from hyperscalers, especially if incumbents lower pricing or match free egress offers, potentially eroding Backblaze’s differentiation. The upmarket push requires investment in sales, support, and product, with risk of execution missteps or elongated sales cycles. Customer retention could be pressured if further price increases are required or if macro headwinds prompt cost optimization among enterprise clients. Regulatory and data sovereignty issues may also add complexity as the business scales globally.
Forward Outlook
For Q1 2024, Backblaze guided to:
- Revenue of $29.6 to $30 million
- Adjusted EBITDA margin of 4% to 6%
For full-year 2024, management raised confidence and narrowed guidance:
- Revenue of $126 to $128 million (25% YoY growth at midpoint)
- Adjusted EBITDA margin of 8% to 10%
- Year-end cash of at least $20 million
Management highlighted several factors that underpin guidance:
- Continued upmarket momentum and larger deal wins
- Stable retention and minimal churn post-price increase
- Disciplined capital allocation and declining lease obligations
Takeaways
Backblaze is executing a high-conviction pivot toward open cloud leadership, with B2 Cloud Storage growth, margin expansion, and upmarket wins validating the strategy. The company’s transparent pricing, free egress, and partner ecosystem are resonating with enterprise buyers seeking alternatives to hyperscalers.
- Margin and Retention Strength: Gross margin gains and resilient customer retention post-price hike suggest durable pricing power and operational leverage.
- Upmarket and Product Innovation: Larger enterprise deals, new channel programs, and AI workflow integration are diversifying the revenue base and positioning Backblaze for long-term growth.
- Investor Watchpoint: Monitor execution on upmarket sales, customer mix evolution, and the pace of AI-driven demand as key levers for 2024 and beyond.
Conclusion
Backblaze’s Q4 marks a turning point as the company achieves profitability and accelerates its transformation into an enterprise-focused, open cloud storage provider. The combination of strong B2 Cloud Storage growth, margin expansion, and disciplined capital management sets a solid foundation for durable growth and competitive differentiation in 2024.
Industry Read-Through
Backblaze’s results reinforce a broader shift away from closed, high-fee hyperscaler models toward open, interoperable cloud ecosystems. The company’s traction with media, entertainment, and AI-driven workflows signals growing demand for specialized, affordable storage solutions that integrate with best-of-breed compute and networking partners. As enterprises scrutinize cloud costs and seek flexibility, providers offering transparent pricing and open architectures are likely to gain share. Incumbents may face pressure to revisit egress fees and contract lock-ins, while channel and partner-driven go-to-market models will become increasingly important across the cloud infrastructure landscape.
