Plexus Secures $6 Million in Strategic Funding to Power Global Expansion and AI-Led Legal Innovation
In a bold move signaling the next phase of its growth, Plexus—an AI-powered legal automation platform that’s redefining how in-house legal teams operate—has secured over $6 million in fresh funding. The round, led by existing shareholders alongside Seattle-based investment firm Lighter Capital, represents Plexus’ first institutional capital raise and underscores the rising momentum behind legal technology’s transformation.
This investment marks a pivotal moment for the company as it prepares to scale globally, build next-generation AI capabilities, and expand its team of world-class talent. With the legal industry poised for sweeping technological change, Plexus is positioning itself at the forefront of innovation, aiming to replace outdated legal workflows with intelligent automation and digital tools.
Accelerating a Global Legal Tech Revolution
Founded to modernize the legal function, Plexus has consistently challenged the conventional model of legal service delivery. With enterprises under pressure to move faster and operate leaner, traditional legal structures have often proven too slow, manual, and expensive to meet the needs of modern business.
Plexus founder and CEO Andrew Mellett emphasized that this funding round is more than a financial milestone—it’s a testament to the growing appetite for transformative legal solutions and an indicator of where the industry is heading.
“We are seeing a once-in-a-generation shift in how legal work is performed,” said Mellett. “Legacy legal operating models are simply not fit for purpose in today’s environment. Businesses need legal solutions that are faster, smarter, and more scalable. This is where Plexus comes in.”
Mellett envisions a future where legal work is done not by tracking progress across spreadsheets or email chains, but by AI-powered systems that handle tasks autonomously—intelligently and securely.
“The global legal industry is valued at a staggering $1.1 trillion, which is three times larger than the global software market,” he noted. “Over the next decade, we expect a significant migration from manual, document-based work to data-driven legal operations powered by machine intelligence. Plexus is leading that charge.”
Strategic Partnership with Lighter Capital
A key component of this funding round is the new partnership with Lighter Capital, a U.S.-based venture debt firm known for its track record of supporting high-growth SaaS businesses. Unlike traditional equity investors, Lighter Capital specializes in non-dilutive financing models, allowing founders to retain control while accessing the capital they need to scale.
Matthew Dowling, Investment Director at Lighter Capital, expressed strong confidence in Plexus’ trajectory.
“Plexus stood out to us for its outstanding growth, strong customer base, and the traction it has gained in one of the fastest-growing verticals in B2B SaaS—legal automation,” said Dowling. “We are excited to support the next phase of their journey and believe this investment will catalyze a new wave of innovation in legal technology.”
Lighter Capital’s involvement brings not just capital, but strategic experience that will support Plexus as it navigates expansion into new markets and delivers advanced AI products for enterprise legal teams.
“This raise is not just about scaling a business—it’s about shaping the future of legal services,” Dowling added. “Plexus is moving legal operations from analog to digital at a time when business leaders are demanding more from their legal departments.”
From Workflow Tools to Digital Lawyers
What started as a platform focused on workflow efficiency has evolved into a comprehensive operating system for legal teams—one that is now transitioning toward a more ambitious vision: digital lawyers.
With its latest round of investment, Plexus plans to deepen its AI capabilities, enabling the platform to move beyond task automation to actual legal reasoning and execution. This includes using AI to review contracts, draft responses, assess legal risk, and facilitate cross-department collaboration.
“As legal workloads grow in both volume and complexity, our clients need more than workflow tools,” explained Mellett. “They need a platform that can act as an extension of their legal team—one that operates at scale, around the clock, and with precision.”
Plexus is already deployed by over 250 leading global brands—including Nike, L’Oréal, Coca-Cola, PepsiCo, Woolworths, and AIA—who rely on the platform to manage everything from contract review and approvals to compliance workflows and legal intake.
“These organizations are pushing the envelope of what’s possible in legal tech,” said Mellett. “They’re embracing digital transformation across the enterprise, and we’re proud to be the partner that’s helping them bring legal along on that journey.”
One of the platform’s key differentiators is its ability to empower business users—outside the legal department—to engage with legal processes more effectively. By embedding legal guardrails and AI-driven guidance into business workflows, Plexus helps reduce bottlenecks while maintaining compliance and oversight.
“We’re not replacing lawyers—we’re unlocking their value,” Mellett emphasized. “By eliminating low-value, repetitive work, legal teams can focus on strategy, risk management, and business partnering. That’s the future of legal.”
The Road Ahead: Expansion, Talent, and Product Development
With the new capital in hand, Plexus is now doubling down on three core priorities: international expansion, product innovation, and talent acquisition.
On the expansion front, the company plans to enter several new markets across North America, Europe, and Asia-Pacific, building on its strong customer base in Australia and other regions.
At the same time, significant investments will be made into the product roadmap, including the development of proprietary AI models tailored for legal use cases. These models will support functions like contract lifecycle management, legal triage, regulatory compliance, and real-time risk assessment.
Lastly, the company is on the hunt for top-tier talent across engineering, data science, customer success, and legal operations. According to Mellett, building a diverse, world-class team is central to maintaining the company’s competitive edge.
“Talent is the foundation of innovation,” he said. “We’re committed to hiring people who share our vision and want to build something truly transformative.”
