About
Neos is a cloud-based legal practice management platform designed specifically for personal injury and plaintiff-side law firms, developed and marketed by Assembly Software (formerly known as Assembly Neos, a company formed from the merger of NexFirm and Assembly). Assembly Software focuses exclusively on legal technology for personal injury firms, building a practice management platform around the specific workflow complexities of PI litigation—including medical records management, lien tracking, settlement processing, HIPAA-compliant client communication, and mass tort multi-plaintiff matter grouping. Neos was developed as a modern, cloud-native successor to AbacusLaw and Amicus Attorney, legacy desktop practice management products that Assembly Software also owns.\n\nNeos's platform provides matter management with PI-specific intake workflows, automated document generation for standard PI forms, medical record request tracking, treatment and provider management, demand letter tools, settlement management with distribution calculation, and a client-facing portal for status updates and document collection. The platform's lien management module tracks Medicare, Medicaid, and health insurance liens associated with personal injury settlements—a workflow requirement unique to PI practice that general practice management tools handle poorly. Neos integrates with e-signature providers, medical records retrieval services, and legal payment processors, and includes reporting tools for case stage pipeline management and staff productivity.\n\nNeos competes with Filevine, Litify, and Needles (owned by Assembly) in the personal injury law firm case management market. Assembly Software's consolidated portfolio—spanning multiple legacy and modern legal practice management products with shared PI market focus—gives it a migration path for firms moving from legacy desktop products to Neos's cloud platform. For personal injury law firms evaluating cloud practice management solutions that genuinely address PI workflow complexity rather than adapting general tools, Neos offers a purpose-built modern platform from a vendor with deep PI market specialization.
