Plexus Raises $4.65 Million in Series A, Forms Strategic Alliance with KPMG Law to Accelerate Legal Automation

Australia’s legal tech pioneer secures the largest venture capital raise in the nation’s legal sector history, setting the stage for international expansion and digital transformation of the legal industry.

Australia-based legal technology company Plexus has raised $4.65 million (USD 3.0 million) in a Series A funding round led by KPMG, marking the largest venture capital raise in Australian legal sector history. Other participants in the round include Aconex co-founders Rob Philpot and Leigh Jasper, and Grant Rule, co-founder and Executive Director of Message Media.

Alongside the investment, KPMG Law has entered a strategic alliance with Plexus, aiming to jointly deliver technology-driven legal services that could reshape how legal functions operate across enterprises. The collaboration will combine Plexus’s automation platform, Plexus Gateway, with KPMG Law’s consulting and compliance capabilities to create a unified, digital-first legal service offering.

Driving the Next Wave of Legal Transformation

The new funding will enable Plexus to enhance its legal automation platform and expand internationally. According to Plexus Founder and CEO, Andrew Mellett, the investment marks a pivotal moment in the long-awaited digital transformation of the legal industry.

“We are at the dawn of a 20-year transformation of one of the world’s most conservative industries. We believe that in the future, legal services will be delivered with the ease we expect of flicking a light switch. This investment and alliance represents a giant step towards realising that vision,”

Plexus’s flagship platform, Plexus Gateway, helps in-house legal teams automate workflows, manage contracts, and improve efficiency across enterprise operations. The company’s technology division grew 142% last year, and research firm Gartner recognized it as a “Best Practice” solution for legal functions.

Market Momentum and Industry Validation

The investment comes amid a broader shift in the legal industry, with corporate legal departments moving from manual processes to technology-led solutions. Research by Plexus across 100 Australian General Counsels found that 97% of enterprises expect no significant increase in legal headcount over the next three years, yet anticipate a 111% year-on-year increase in technology investment.

“Like many other industries, legal executives are choosing technology over human investment,” said Mellett. “General Counsels now recognize they need to invest in automation to free their teams for more strategic work. This marks a tipping point for the broader legal industry, and we’re at the forefront of that change.”

Strategic Alliance with KPMG Law

Through its alliance with KPMG Law, Plexus will gain access to one of the region’s most established professional networks.

“In KPMG, we have a partner that is committed to bringing revolutionary legal solutions to clients,” Mellett noted. “They bring instant credibility and unparalleled reach.”

Stuart Fuller, Head of KPMG Law Asia Pacific, said the partnership reinforces both firms’ shared vision of the “future of law.”

“For over seven years, Plexus has been at the cutting edge of legal innovation,” said Fuller. “Our analysis suggests that Plexus Gateway is one of the most advanced legal automation platforms globally. Combined with KPMG Law’s core solutions, we can offer clients a one-stop platform for all legal services.”

The Bigger Picture: Legal Tech on the Rise

The legal technology market, currently estimated at US$15.9 billion, is seeing accelerated adoption as enterprises and law firms seek to automate repetitive processes, improve compliance, and manage costs.

With this round, Plexus strengthens its position as one of the leading players in Australia’s growing legal tech ecosystem — a sector that’s rapidly attracting global investor attention. The company’s international expansion plans, backed by a strategic alliance with a Big Four firm, position it well to influence the next stage of legal innovation in Asia-Pacific and beyond.
