Relativity (originally kCura) was founded in 2001 in Chicago by Andrew Sieja and grew into one of the dominant eDiscovery review platforms used by corporations, law firms, and government agencies. The company has taken roughly $2.35 billion in growth capital over its history, primarily private-equity and growth-equity investment from ICONIQ, Silver Lake, Permira, New Mountain Capital, and Bryant Stibel, rather than traditional venture rounds. It remains headquartered in Chicago, Illinois.

Relativity is a Chicago-based eDiscovery and legal review platform provider, maker of RelativityOne and the aiR generative AI suite.

Relativity (RelativityOne) Company Profile

Relativity ODA LLC

Complex to Set Up: G2 reviewers consistently score ease of setup lower than other categories, reflecting real administrative overhead for new deployments.

Pricing Still Requires a Quote: Despite the shift to per-GB pricing, exact costs depend heavily on data volume and reseller relationships, making upfront budgeting difficult.

Built for Volume, Not Small Matters: The platform and its pricing model are optimized for large-scale review; small firms or single-matter users are generally better served by lighter tools.

Industry-Leading Review Speed: aiR for Review and aiR for Privilege are reported to cut review time by up to 85% versus linear review, while surfacing 10-20% more relevant documents.

AI Included, Not Upsold: Generative AI review and privilege features are now standard in RelativityOne rather than a separate paid tier.

Proven at Enterprise Scale: 20+ years in the eDiscovery market with a 4.6/5 G2 rating across 615+ reviews, the largest review base of any major eDiscovery platform.

Case Strategy Tools: aiR for Case Strategy auto-generates chronologies and fact summaries to help litigators move from review to argument faster.

<h3><strong style="background-color: transparent; color: rgb(0, 0, 0);">Introduction</strong></h3><p class="ql-align-justify"><span style="background-color: transparent; color: rgb(0, 0, 0);">Relativity is the incumbent platform in eDiscovery, used for large-scale document review, investigations, and litigation support by corporate legal departments, law firms, and government agencies. &ldquo;aiR&rdquo; is the umbrella name for Relativity&rsquo;s generative-AI feature set inside its cloud product, RelativityOne, covering document review, privilege screening, natural-language search, and case-strategy support. As of 2026, Relativity has made its core aiR features standard in RelativityOne rather than a paid add-on.</span></p><h3><strong style="background-color: transparent; color: rgb(0, 0, 0);">Legal Research &amp; Review</strong></h3><p class="ql-align-justify"><span style="background-color: transparent; color: rgb(0, 0, 0);">aiR for Review and aiR for Privilege use generative AI to classify and summarize documents during review, with Relativity reporting that customers complete reviews up to 85% faster and surface 10&ndash;20% more relevant documents than with linear review or older technology-assisted review (TAR) approaches. aiR Assist adds natural-language search across a matter&rsquo;s document set, and aiR for Case Strategy auto-generates key facts, chronologies, and document/transcript summaries to help litigators move from raw review to case narrative and witness preparation.</span></p><h3><strong style="background-color: transparent; color: rgb(0, 0, 0);">Predictive Analytics &amp; Case Strategy</strong></h3><p class="ql-align-justify"><span style="background-color: transparent; color: rgb(0, 0, 0);">Beyond document classification, aiR for Case Strategy is positioned as an analytics layer on top of review: visualizing case chronologies, flagging discrepancies across large communication sets (email, Slack, chat), and helping teams prioritize which facts and documents matter most for a given legal theory, rather than predicting case outcomes directly.</span></p><h3><strong style="background-color: transparent; color: rgb(0, 0, 0);">Pricing</strong></h3><p class="ql-align-justify"><span style="background-color: transparent; color: rgb(0, 0, 0);">RelativityOne has moved to volume-based, per-GB pricing rather than per-user licensing, with generative AI review and privilege features now included at no extra cost. As a rough reference point, a 100GB matter has been reported to cost roughly $3,000&ndash;$10,000 per month in platform fees, and Relativity has introduced unlimited, fixed-fee pricing options for aiR usage through certain partners. Exact pricing depends on data volume, matter complexity, and whether it is purchased directly or through a reseller/service provider, so a quote is required for an accurate cost.</span></p><h3><strong style="background-color: transparent; color: rgb(0, 0, 0);">User Reviews and Ratings</strong></h3><p class="ql-align-justify"><span style="background-color: transparent; color: rgb(0, 0, 0);">Relativity holds a strong 4.6 out of 5 rating on G2 across 615+ reviews, among the highest review volumes of any eDiscovery platform, with particularly strong marks for document processing, search speed at scale, and quality of support. Ease of setup scores somewhat lower, reflecting the platform&rsquo;s complexity and the administrative overhead of large enterprise deployments.</span></p><h3><strong style="background-color: transparent; color: rgb(0, 0, 0);">Verdict</strong></h3><p class="ql-align-justify"><span style="background-color: transparent; color: rgb(0, 0, 0);">Relativity remains the safest default choice for large, complex eDiscovery and investigation workloads, and its 2025-2026 aiR rollout has meaningfully closed the generative-AI gap with newer entrants like Everlaw and DISCO by making review AI a standard, not premium, feature. It is a strong fit for enterprise legal, government, and large law firm review teams; smaller matters or budget-constrained teams may find lighter, more transparently priced eDiscovery tools a better fit.</span></p>
