Coral Gables, FL-based case management software company formed from the 2019 merger of Needles (founded 1985) and TrialWorks. CEO Jonah Paransky. 51-200 employees. Flagship product Neos is an AI-driven, cloud-based case management platform hosted on Microsoft Azure. HIPAA-compliant. Primarily targets plaintiff PI firms, also serves insurance defense (confirmed by Reddit user), mass torts, and other litigation practices. G2: 4.5/5 (292 reviews). Capterra: 4.4/5 (200 reviews). Won ‘Case Management Innovation Of The Year’ (LegalTech Breakthrough) and ‘Best Legal Case Management Software 2025’ (Acquisition International). Legacy products Needles and TrialWorks being migrated to Neos. Highly polarizing among paralegals per r/paralegal — long-term Needles users frequently describe Neos as inferior to its predecessor, particularly for document navigation (SharePoint-based ‘list view’ vs. traditional folders). Customer support quality disputed across Reddit threads. Forced Needles-to-Neos and TrialWorks-to-Neos migrations are the primary source of negative sentiment. Key strength is deep PI heritage (35+ years via Needles) and large existing user base. Primary competitors: Filevine, CasePeer, SmartAdvocate. 3-license minimum — not for solo practitioners. Pricing requires consultation (opaque). NeosAI capabilities described as ‘AI-infused’ but specifics thin. RingCentral integration confirmed via conference presentation.
