Editor’s Note: The eDiscovery cloud software category is rebalancing across 2025-2030. Reconciled estimates place worldwide cloud spending at approximately $5.29 billion in 2025 – 79 percent of the software segment – and project growth to $8.87 billion in 2030 at a reconciled compound annual rate of 10.93 percent. Inside the cloud category, SaaS holds approximately 67 percent of spend in 2025 and 63 percent in 2030, while platform-as-a-service rises from 15 percent to 17 percent and infrastructure-as-a-service from 18 percent to 20 percent. The four-percentage-point SaaS share decline reflects a structural rebalance toward platform and infrastructure tiers as advanced eDiscovery workloads run against those services directly.

The driving force is concrete: AI inference at scale, vector search, large-scale processing pipelines, and multi-source ingestion architectures increasingly engage platform and infrastructure services rather than terminating at packaged SaaS endpoints. Some of that activity appears in vendor SaaS revenue when wrapped into packaged offerings; some appears as direct PaaS or IaaS spend by service providers and enterprise customers operating against hyperscaler accounts.

For cybersecurity, data privacy, regulatory compliance, and eDiscovery professionals, three observations follow. First, the cloud bill of materials for advanced eDiscovery work now spans SaaS, PaaS, and IaaS simultaneously – and procurement evaluation needs to extend across the full stack rather than terminate at the SaaS subscription line. Second, AI inference economics specifically deserve their own line in vendor evaluation and contract review, because the inference cost component is increasingly material. Third, the SaaS-anchored cloud category is not retreating – it is growing alongside an expanding platform and infrastructure tier that procurement frameworks and vendor evaluation criteria are still adapting to.

Industry Research – eDiscovery Market Sizing Beat

Market Intelligence: eDiscovery cloud software – SaaS, PaaS, and IaaS, 2025 to 2030

Cloud software grows from $5.29 billion in 2025 to $8.87 billion in 2030 at a reconciled 10.93 percent CAGR, with SaaS holding two-thirds of the category but losing share as PaaS and IaaS components compound at faster rates

ComplexDiscovery Staff

SaaS still dominates eDiscovery cloud spending, and will throughout the 2025-2030 cycle. Reconciled estimates place worldwide SaaS spending at approximately $3.54 billion in 2025 against $0.79 billion for platform-as-a-service and $0.95 billion for infrastructure-as-a-service – a 67-15-18 split inside the off-premise software category. By 2030, the split rebalances to 63-17-20 as PaaS and IaaS components compound at faster rates than SaaS. The headline cloud growth – 10.93 percent CAGR, taking the category from $5.29 billion to $8.87 billion – hides a more interesting story about where AI workloads are landing inside the cloud stack.

The 2025 cloud composition baseline

In 2025, reconciled estimates place worldwide eDiscovery cloud software spending at approximately $5.29 billion – the off-premise category that already holds 79 percent of total software spend. Inside the cloud category, SaaS accounts for approximately $3.54 billion (67 percent), platform-as-a-service for approximately $0.79 billion (15 percent), and infrastructure-as-a-service for approximately $0.95 billion (18 percent). The starting composition is recognizable: SaaS dominates because it is the cloud delivery model that vendors built their eDiscovery products around during the prior decade. PaaS and IaaS appear as distinct line items because customers and providers increasingly engage with cloud services at the platform and infrastructure tiers directly, alongside packaged SaaS subscriptions.

SaaS: still dominant, but losing share

SaaS grows from $3.54 billion in 2025 to approximately $5.59 billion in 2030 at a reconciled compound annual rate of approximately 9.6 percent. The growth is meaningful in absolute terms – a five-year increase of close to 58 percent – but the SaaS CAGR runs below the overall cloud CAGR (10.93 percent), which means SaaS share of cloud spend declines from 67 percent to approximately 63 percent across the period. SaaS continues to anchor the cloud category because most eDiscovery vendor products ship as SaaS subscriptions, and most buyer evaluation cycles default to SaaS pricing. The share decline is gradual, the absolute growth is durable, and SaaS will remain the largest cloud sub-category throughout the cycle and well past it.

PaaS and IaaS: where AI inference workloads are landing

Platform-as-a-service grows from $0.79 billion in 2025 to approximately $1.51 billion in 2030 at a reconciled compound annual rate of approximately 13.8 percent – the fastest-growing cloud sub-category by CAGR. Infrastructure-as-a-service grows from $0.95 billion to approximately $1.77 billion at roughly 13.3 percent. Both compound materially faster than SaaS, and the reason is concrete: advanced eDiscovery workloads increasingly run against platform and infrastructure services rather than against packaged SaaS endpoints. AI inference at scale, vector search and retrieval-augmented generation, large-scale processing pipelines, multi-source ingestion architectures, and AI model fine-tuning each touch platform and infrastructure layers directly. Some of this spend appears in vendor SaaS revenue when the vendor wraps the underlying services into a packaged offering. Some appears as direct PaaS or IaaS spend by service providers building their own pipelines or by enterprise customers operating eDiscovery work in-house against hyperscaler accounts.

The composition rebalances by 2030

The 2030 cloud composition is 63 percent SaaS, 17 percent PaaS, and 20 percent IaaS – a four-percentage-point share decline for SaaS and a four-percentage-point combined share gain for PaaS and IaaS across five years. The cloud category remains SaaS-anchored, but the platform and infrastructure tiers have grown into meaningful line items rather than rounding adjustments. The rebalance matters because the cloud bill of materials for advanced eDiscovery work increasingly spans all three layers simultaneously. A managed-review engagement may run on SaaS, but the AI inference behind that review may run on PaaS, and the underlying compute may bill at the IaaS tier. Procurement evaluation, contract structure, and cost transparency increasingly extend across the full stack rather than terminating at the SaaS subscription line.

What it means for vendors, providers, and buyers

For software vendors, the SaaS share decline does not undermine the SaaS business; it simply means the cloud category has expanded around SaaS rather than only through SaaS. Vendors that wrap PaaS and IaaS services into transparent SaaS offerings retain pricing power. Vendors that leave platform and infrastructure exposure unwrapped should expect customers to ask procurement-level questions about the split. For service providers, direct hyperscaler relationships – operating large-scale processing, AI inference, and data pipelines on PaaS and IaaS infrastructure – become an increasingly visible category of spend that influences operating margin and competitive positioning. For buyers, cloud cost transparency now spans all three layers, and AI inference economics specifically deserve their own line in vendor evaluation and contract review.

What comes next in the Market Intelligence series

Subsequent Market Intelligence analyses move beyond the software view into the geography and demand-sector lenses, examining where international markets compound faster than the United States and how government and regulatory demand differs from non-government in deployment, contract structure, and pricing. The direct delivery approach view examines how corporate, government, law firm, and service provider channels each consume eDiscovery work. The series will close with the consolidated 2025-2030 eDiscovery Marketplace Mashup as the synthesis point.

The figures presented here are reconciled estimates aligned to a common scope (worldwide eDiscovery cloud software, including SaaS, PaaS, and IaaS components within the off-premise category), a common geography, and a common timeframe (calendar years 2025 through 2030). They draw on publicly available third-party research, vendor disclosures, and analyst evaluation aggregated within the underlying market model. Forward estimates from past and present industry data sources are included in the model and presented as the current reconciled view. The 2025-2030 eDiscovery Marketplace Mashup is complete in its underlying analysis but remains unpublished in its consolidated form at this time. It will be published as the culmination of the Market Intelligence series, with the full source list, citation guidance, and methodology disclosure included at that time.

If PaaS and IaaS continue to compound faster than SaaS, will the cloud bill of materials for advanced eDiscovery workloads eventually shift the procurement conversation away from SaaS-centric subscription pricing and toward stack-level transparency – or will eDiscovery vendors successfully wrap platform and infrastructure exposure inside packaged SaaS offerings that preserve the simpler buyer evaluation cycle that SaaS pricing has historically enabled?
