Plexus

Plexus, operating as plexus.co, is a legal technology company founded in Melbourne, Australia, in 2011 by Andrew Mellett. Drawing from his experience as a director at the Corporate Executive Board, where he advised executives across the Asia-Pacific and Europe, Mellett identified a dual dissatisfaction within the legal industry: clients felt they were receiving poor value from traditional law firms, and lawyers were unhappy with the work-life proposition. This insight led to the creation of Plexus with a co-founder, aiming to reshape the legal sector through a technology-centric approach.

The company's core offering is an AI-powered legal operating system designed for in-house legal teams. This platform provides modules for Legal Automation, Matter Management, and Contract Management, which can be adopted individually or as an integrated suite. The system automates workflows, manages legal tasks from intake to completion, and centralizes contract storage and management. Key features include document and contract automation, e-signatures, renewal reminders, matter triage, and compliance tools for marketing campaigns. By streamlining these processes, Plexus enables legal departments to reduce manual workloads, manage risk, and focus on higher-value strategic work. The business generates revenue through a Software-as-a-Service (SaaS) model, serving enterprise clients with its technology platform.

A significant milestone occurred in November 2022 when Plexus divested its legal talent secondment division, Plexus Engage, to the global legal resourcing firm Axiom. This strategic move allowed Plexus to focus exclusively on its technology offerings. Over the years, the company has secured notable funding, including a A$4.65 million round in 2019 led by KPMG and a further $6 million in 2025 from existing shareholders and Lighter Capital to fuel AI development and international expansion. Headquartered in Melbourne, Plexus has established an international presence with offices in Sydney, London, and Washington D.C. In March 2023, Andrew Mellett transitioned to the role of Executive Director, with Craig Harris, a seasoned SaaS executive, appointed as the new CEO.
