Editor’s Note: Andrew Haslam built the eDisclosure Systems Buyers Guide to help practitioners make better decisions, and as the guide enters its 14th year, the 1H 2026 update makes clear that mission remains firmly intact. What began as Andrew’s personal contribution—shared freely with the community as a practical resource and, in many ways, a gift to the industry—has matured into one of the most trusted reference points for eDiscovery professionals. Now published by ComplexDiscovery OÜ in collaboration with EDRM, this latest update leads with eight new long-form articles spanning market dynamics and technology coverage, including the Winter 2026 eDiscovery Pricing Survey, 2H 2025 Business Confidence Survey results, a running M&A tracker, a new Total Success Predictor Rating framework for vendor viability, and timely analysis on deployment flexibility and product management in legal technology. Supported by ongoing curation—including 164 supplier listings and 68 software listings—this edition reflects the contributions of Holley Robinson, senior marketing operations manager at ComplexDiscovery OÜ, and the continued collaboration and support of Mary Mack and the EDRM community.
Reader engagement tells the other half of the story. With more than 321,957 pageviews since the start of 2024 and over 70,000 in 2026 alone, the guide’s sustained audience underscores the value of its open-access, practitioner-first approach. That continued use reflects a broader need across cybersecurity, information governance, and eDiscovery disciplines for resources that do more than report change—they help interpret it.
In that respect, the Buyers Guide functions as both a roadmap and a historical record. It provides a forward-looking lens on the decisions practitioners are making now while preserving a longitudinal view of how the industry has evolved over time. As frameworks like the Total Success Predictor Rating enter the conversation, the real test will be adoption—whether they become part of the shared vocabulary professionals use to evaluate vendors and strategies in the months ahead.

Andrew Haslam’s eDisclosure Systems Buyers Guide at 14: What the 1H 2026 update reveals
ComplexDiscovery Staff
Andrew Haslam’s eDisclosure Systems Buyers Guide just entered its 14th year. It still reads like the project of a working practitioner who wanted peers to have better information than they could easily find anywhere else.
That is not accidental. It is the inheritance of how the guide was built.
The 1H 2026 update of the guide, published by ComplexDiscovery OÜ in collaboration with EDRM, leads with eight new long-form articles across market dynamics and technology area coverage, updates two items in the introduction section, and carries 164 supplier listings and 68 software listings as its running catalog of the eDiscovery market. Each addition reinforces what Haslam established in 2013 when he first compiled a PDF buyers guide in his own time and shared it at no cost — that the eDiscovery community benefits most when somebody takes responsibility for the connective tissue between vendors, practitioners, and emerging technology.
Haslam stepped back from active authorship after the 2022 edition to reclaim weekends with family, entrusting stewardship of the guide to ComplexDiscovery OÜ. The transition from annual PDF to dynamic online knowledge base was not a retirement gesture. It was a generational one. Haslam knew the market had moved past what any single person could maintain at volume, and he wanted the guide to keep pace without losing its posture.
Four new market dynamics articles
The 1H 2026 update adds four new entries to the market dynamics section. “A Complete Analysis of the Winter 2026 eDiscovery Pricing Survey,” co-produced with EDRM across a December 2025 through February 2026 data collection window, surfaces findings from 53 respondents across 25 pricing questions spanning forensic collection, data processing and hosting, document review, and generative AI-assisted review. Forensic collection rates have stabilized in the $250 to $350 per hour range for standard work, infrastructure-level hosting has commoditized, and GenAI-assisted review pricing remains experimentally diverse, with hybrid billing and per-document models each claiming roughly 28 percent of reported primary models.
“The M&A Risk of Confusing Market Velocity with Marketing Capability” examines a pattern that the Winter 2026 pricing data made newly visible. Technology acquirers often price target deals for brand strength when what they are actually buying is a time-bounded technology premium, and the distinction matters at the negotiation table. The piece provides readers with a practical framework for separating the two before underwriting terms.
“Confidence Meets Complexity: Full Results from the 2H 2025 eDiscovery Business Confidence Survey” brings the sector-sentiment read. The 38th edition of the long-running benchmark captured responses from 64 industry leaders and found 59.38 percent rating current conditions as “good” — a decisive shift from the “normal” ceiling that defined prior cycles. The same respondents, however, reported opacity on day-to-day financial levers such as Days Sales Outstanding and Monthly Recurring Revenue. The analysis highlights the visibility gap and provides operators with a starting point for closing it.
“eDiscovery Mergers, Acquisitions, and Investments” completes the market dynamics additions in the 1H 2026 cycle as the guide’s running tracker of deal activity across the sector. The article catalogs recent transactions, rolls them against a multi-year retrospective of industry consolidation, and gives buyers, sellers, and operators a single reference for the deal-flow that is actively reshaping the vendor landscape. Practitioners running a vendor evaluation this quarter should check the M&A tracker first — a vendor mid-acquisition or mid-divestiture is a different operational risk profile than the same vendor a year earlier or later, and the tracker surfaces that context in time to act on it.
Four new technology area articles
The technology area coverage grows by four articles in the 1H 2026 update, and each one speaks to a current operating decision. “Making the Subjective Objective: A Scoring Framework for Evaluating eDiscovery Vendor Viability in 2026” introduces the Total Success Predictor Rating, a four-category scoring model designed to translate subjective vendor impressions into comparable, defensible numbers. The companion piece, “eDiscovery Vendor Viability Scoring Tool: Making the Subjective Objective,” provides the working tool that accompanies the framework so practitioners can score their own vendor shortlists rather than simply read about the method.
“Beyond Public Cloud: The Enduring Case for Deployment Flexibility in eDiscovery” makes an argument that current market coverage has largely missed. Cloud-first strategy dominates vendor messaging, but a substantial segment of the market continues to demand private cloud and on-premise deployment for regulatory, sovereignty, and operational reasons. Teams working regulated financial, healthcare, and government matters should not be told their deployment needs are legacy — they are current, and in some verticals, they are growing again. The overview equips buyers with the language to push back on cloud-only sales motions when their matter profiles call for it.
The final addition, “Evolving Product Lifecycle Management: The Expanding Role of Product Managers and Democratized Prototyping in Legal Technology,” addresses the widening gap between legal tech delivery timelines and consumer technology development speed. As low-code tooling and vibe-coding platforms lower the barrier to functional prototypes, product managers in the legal technology space are being asked to run shorter feedback cycles against compliance-heavy requirements. The article provides a working model for practitioners who are being asked to modernize their development practices without sacrificing governance.
Two introduction items, updated for 2026
The update also revisits the Executive Summary and Foreword. The Executive Summary frames the year through three converging forces: stabilizing core pricing, fragmenting AI-assisted review economics, and an operational maturity gap between leadership confidence and financial visibility. The Foreword aligns Haslam’s original intent with the guide’s current form, preserving its voice while marking its evolution under ComplexDiscovery OÜ’s stewardship.
For practitioners onboarding new team members, briefing executives, or structuring vendor evaluations, the introduction section serves as a concise and practical orientation.
164 supplier listings and 68 software listings
The operational core of the guide remains its listings. The 1H 2026 edition includes 164 suppliers and 68 software offerings, maintained as a continuous catalog rather than rebuilt each cycle. The listings are curated by Holley Robinson of ComplexDiscovery OÜ, with the support of Mary Mack and the EDRM community, reinforcing the guide’s practitioner-driven foundation.
Experienced users treat each entry as a triangulation point rather than a definitive source—cross-referencing vendor claims with public information and peer experience. Alignment across those views builds confidence; divergence becomes a signal worth investigating.
Pageview data that validates the posture
What sets this update apart is not just breadth, but depth of insight. Since the beginning of 2024, the guide has drawn more than 321,957 pageviews, with over 70,280 recorded through March 2026 alone. That sustained engagement reflects continued demand from legal, compliance, and cybersecurity professionals for resources that cut through complexity with clarity.
The traffic pattern also validates the stewardship model. Practitioners return to the guide as an ongoing reference, not a one-time read, and current trends suggest readership is pacing ahead of prior years. That level of engagement provides a meaningful signal for editorial direction and future coverage.
Part current roadmap, part historical record
One framing is worth naming directly. The Buyers Guide functions as two things at once. Part of it is a current roadmap — the new market dynamics articles, the pricing benchmarks, the Total Success Predictor Rating tool, and the deployment flexibility argument all point toward decisions practitioners are about to make. Part of it is a historical record — a running archive of how the industry has evolved across a decade-plus of listings, surveys, and editorial commentary.
Readers who use only the roadmap layer miss the signal that comes from reading the archive. A supplier profile from 2019 read against the same supplier today tells its own story about consolidation, product positioning, and regional shifts. A pricing survey from 2022 read against the Winter 2026 survey marks where the floor moved and which line items commoditized. The guide rewards both uses, and the 1H 2026 update was assembled with both readers in mind.
A guide that continues because somebody cared enough to start it
What makes the 1H 2026 update worth attention is the same quality that defined the first edition: sustained, practitioner-focused stewardship. The guide remains openly accessible, reflecting Haslam’s original decision to offer it as a contribution to the community.
For readers deciding how to approach it, the path is straightforward. Start with the Executive Summary and Foreword to establish context. Review the Winter 2026 pricing analysis to understand cost pressures shaping vendor conversations. Then apply the Total Success Predictor Rating to an active vendor evaluation. That sequence alone can produce a concise, defensible market assessment.
Used alongside analyst research, practitioner communities, and trade reporting, the Buyers Guide helps complete the operating picture of the eDiscovery market.
What does it say about an industry when its most trusted reference document is still, in its bones, a gift? And what should that tell buyers about where the next decade of eDiscovery intelligence will—and will not—come from?
