Case Management · Platform Profile
Neos is the cloud successor to Needles and TrialWorks — Assembly Software's case management platform for plaintiff firms, with an embedded AI layer (NeosAI) whose adoption grew 350% in 2025.
Neos is the product of a merger of legacies: Assembly Software was formed in 2019 to unite Needles (a case management name dating to the 1980s) and TrialWorks (from the 1990s), under private-equity backing from Ridge Road Partners. Neos is the cloud rewrite that succeeded both — browser-based, built on Microsoft Azure, and headquartered out of Coral Gables, Florida. The company reports more than 1,450 firms on the platform.
The system manages the plaintiff case lifecycle — intake through settlement — with documents, tasks, deadlines, calendaring, settlement tracking, and reporting. NeosAI, its embedded AI layer, provides record summarization, demand and document drafting, medical chronologies, data extraction, chat-based case analysis, and automated document classification and filing. Assembly's December 2025 year-in-review claimed more than 500,000 attorney hours saved via NeosAI, with AI adoption up 350 percent year over year.
For the many firms still running Needles or TrialWorks server installs, Neos is the designated migration path: Assembly's development and AI investment flow to Neos, and the company markets migration tooling from both legacy products. It has held G2 Leader status in legal case management through 2026.
Plaintiff personal injury firms first and foremost — auto, med-mal, mass tort, workers' comp, premises liability — from growing practices to high-volume operations. The natural constituency is the installed base of legacy Needles and TrialWorks firms deciding where to land next.

Neos competes in the PI-native tier against SmartAdvocate, CloudLex, and CasePeer, and against Filevine and Litify at the larger end. Its differentiation is the embedded AI strategy: NeosAI ships inside the platform rather than as a separately branded add-on suite, and Microsoft has publicly cited it as a strong AI implementation on Azure.
For legacy Needles and TrialWorks firms, the stack question is really a migration question — when, not whether. The legacy products are no longer where the vendor's investment goes, so the open decision is timing a Neos move, or using the decision point to survey the whole market.
Neos is the successor platform. Assembly's development and AI investment are in Neos, and it markets migration paths from both legacy products.
