Company Description:
3Rive Technologies is a legal technology company and Alternative Legal Service Provider (ALSP), founded in 2015 and headquartered in Australia. It serves law firms and in-house legal teams in the UK, Australia and the Middle East, with the UK as its primary market. Delivery runs from a 120-plus-person center in Colombo, Sri Lanka, certified to ISO/IEC 27001:2022 by Bureau Veritas under UKAS accreditation.
The firm works on a simple observation: most legal AI stops at the document, yet much of a firm’s cost sits in the work that follows, such as billing, onboarding, matter administration and reporting. 3Rive builds systems that sit on top of the platforms a firm already uses rather than replacing them, and stays in place to run them after go-live. Its commercial model, Cognitive Outsourcing™ (UK registered trademark UK00004278423), takes over a defined function, rebuilds it with AI, shares the savings with the client and hands the AI assets back at the end of the term.
3Rive has spent seven years embedded in a top 30 global insurance-led law firm. It is a Registered Partner in Anthropic’s Claude Partner Network, a Microsoft partner, and a finalist for Supplier of the Year at the Legal Technology Awards 2026. Chuck Silva (Founder & CEO) chairs the company and chaired the 9th World Legal Tech & AI Summit in Berlin in 2026, while Don Amaratissa (Co-Founder & CTO) leads engineering and AI delivery.
Offerings:
3Rive provides data, AI, outsourcing, and implementation services to law firms and legal teams:
- Legal data platform. Brings data scattered across a firm’s separate systems into one governed Microsoft platform, so partners and finance teams can see it and ask questions in plain English.
- Billing and finance operations. Reconcile disbursements, check billing narratives before invoices go out, and show unbilled and unpaid work in real time.
- Knowledge graphs. Links to a firm’s matters, clients, and documents related to precedent and potential conflicts surface quickly.
- AI legal tools inside the firm’s own environment. Redaction, knowledge search and matter chronologies that run within the firm’s own systems, so client data never leaves its control. Redaction finds personal and privileged material, can be reversed, and keeps a full audit log.
- OnePane. One conversational interface that lets fee earners query HR, billing, CRM, time, and expenses systems without switching between them.
- Cognitive Outsourcing™. A managed service in which 3Rive runs a back-office function, redesigns it with AI and shares the savings with the client.
- Legal process outsourcing. Document review, early case assessment, and claims operations, including AI-assisted triage of case merits before committing to full review costs.
- Managed capacity. Dedicated engineering and legal technology teams that work as an extension of the firm’s own staff.
- Platform implementation. Delivery of practice management, document management and automation platforms, including iManage migrations.
- Client and matter onboarding. Intake, conflict checks and anti-money laundering screening run side by side, with a full audit trail.
- AI readiness assessment. A five-day review of a firm’s systems, processes and governance, ending with a costed 90-day plan.
