Legal Industry Challenges We Solve
We understand the unique demands of the legal services and legal technology industry and build solutions that address them head-on. With a market size of $28B global legal tech market, 20% CAGR, thelegal sector demands technology partners who truly understand the industry.
Document Management & Automation
Law firms handle millions of documents: contracts, briefs, discovery materials, and correspondence. They need intelligent document management with version control, full-text search, automated template generation, and AI-powered clause extraction — all with strict access controls and audit trails.
Client Portal & Communication Security
Attorney-client privilege demands the highest level of communication security. Client portals must provide encrypted messaging, secure document sharing, matter status updates, and billing transparency — all behind multi-factor authentication with comprehensive access logging.
Case & Matter Management Systems
Managing cases across multiple attorneys, paralegals, and practice areas requires sophisticated workflow tools: deadline calendaring, task assignment, time tracking, conflict checking, and matter-level financial management with trust accounting support.
E-Discovery & Compliance
Modern litigation involves terabytes of electronic data. E-discovery platforms must collect, process, review, and produce electronic documents according to Federal Rules of Civil Procedure. AI-powered review can reduce document review costs by 60-80%, but the technology must be defensible in court.
