Filevine vs Supio: pricing, features and which to choose

Filevine was founded in 2014 in Salt Lake City by Ryan Anderson, its CEO, and grew from a personal injury case management tool into a broad legal platform. It says nearly 6,000 customers and 100,000 legal professionals use it, from boutique firms to government agencies and Fortune 500 companies, and that users upload more than 20 million pages of documents a day. In September 2025 Filevine announced $400 million in equity funding over two rounds led by Insight Partners, Accel and Halo Fund, which Law.com reported put its valuation at about $3 billion. Its core customers remain plaintiff litigation firms, though it also sells contract management and products for in-house and public sector teams.

Filevine's case management centralizes everything about a matter: contacts, documents, emails, text messages, phone logs, deadlines, calendars, tasks, notes, intake forms and audit logs. Firms configure custom project templates, fields and workflows for each practice area, and automations move cases between phases. Other modules cover lead intake, document assembly, e-signature, timekeeping and billing, client texting, reporting dashboards and contract lifecycle management. Implementation is handled by Filevine and certified partners. The platform runs on AWS and offers APIs and integrations with Microsoft 365, Google, accounting tools and others. Its depth of configuration suits firms with established processes but means setup takes real work.

Filevine's strengths are deep, configurable case management, AI that works with the full context of each matter, strong deposition tools, medical chronologies for injury firms and heavy investment in product. Its weaknesses are opaque pricing, AI billed separately by project, a configuration-heavy setup and a feature set that can be more than small firms need. Litify offers a similar Salesforce-based platform with native AI agents. Clio is simpler and better known among small firms. EvenUp and Supio focus on AI for personal injury demands and case analysis. CaseMark sells AI deposition summaries per file. Choose Filevine if you want case management and legal AI in one system.

Supio is a Seattle legal AI company focused on personal injury and mass tort plaintiff firms. It emerged from stealth in August 2024 with a $25 million Series A, then announced a $60 million Series B on April 30, 2025, bringing reported total funding to $91 million. Sapphire Ventures led the Series B, with Mayfield and Thomson Reuters Ventures participating. Supio is built for firms processing substantial case records and portfolios, rather than for general legal question answering. Its named workflows include chronologies, demand letters, case ledgers, litigation drafting, intake, and agentic case operations. The company describes specialized, purpose-built AI models and human expert verification, but does not name the foundation model vendors behind the service.

Supio organizes case preparation around document intelligence and structured outputs. Case Economics, Case Signals, and the Drafting Suite address different stages of reviewing records and producing work product. Teams can create chronologies, demand letters, case ledgers, and litigation drafts. Supio Intake conducts intake around the clock, scores leads, and writes structured case data to a case-management system. Supio Agent, launched in May 2026, plans and executes finished work with attorney oversight at case, portfolio, and firm levels. Connectors support integrations and two-way CMS synchronization, while a Westlaw Advantage connection was announced in April 2026. The practical design is a shared operating layer for case preparation, lead handling, and drafting, rather than a single document-generation utility.

The main buying risk is opacity around commercial and technical details. Supio does not publish dollar prices, named model vendors, API limits, retention schedules, or self-hosted deployment options. EvenUp is the closest specialist comparison, covering plaintiff-injury intake, treatment, demands, negotiation, discovery, and trial, with MedChrons combining AI and professional or nurse review. Filevine’s LOIS is broader case-management software that acts on matters, deadlines, documents, and appointments inside its system of record. Litify combines Salesforce-based practice management with agentic workflows and a Supio-powered damages assistant. Supio should be picked by plaintiff firms wanting dedicated case intelligence, intake, drafting, and portfolio automation, provided a custom quote and contract answer their integration and governance requirements.
