Plexus secures $6 million to accelerate AI-driven growth strategy

Plexus, the AI-powered legal automation platform trusted by global enterprises, has secured over $6 million in new funding to accelerate global expansion and AI-led innovation.

The raise, led by existing shareholders and Seattle-based Lighter Capital, marks Plexus’ first institutional partnership. The funds will fuel expansion into key international markets, accelerate AI product delivery, and onboard the next wave of exceptional talent.

Plexus founder and CEO Andrew Mellett said the raise is a clear indicator of the rising demand for more innovative legal and compliance solutions, and the substantial market opportunity ahead.

“Traditional legal operating models simply can’t keep up with the pace of modern business,” said Mellett. ​“We’re witnessing a once-in-a-generation shift: from tracking legal work to getting it done automatically and intelligently.”

“The global legal industry is valued at $1.1 trillion, three times the size of the entire software market. Over the next decade, the industry will shift from consonants and vowels to zeros and ones, and Plexus is at the vanguard of that transformation.”

"This capital gives us the firepower to accelerate what’s already working, build the next wave of capabilities, and help our customers scale legal value faster than ever."

Strategic capital partnership with Lighter Capital 

After receiving interest from several leading investment firms, Lighter Capital was selected for its proven experience supporting high-growth SaaS platforms and alignment with Plexus’ strategic direction.

“Lighter Capital is privileged to support Plexus in their latest financing round,” said Matthew Dowling, Investment Director at Lighter Capital. ​“With recent growth and solid business metrics, Plexus was a perfect fit for Lighter Capital’s non-dilutive financing. Automation in the legal space is one of the fastest-growing sectors in B2B SaaS, and Plexus is in a great position to capture more of the market. 

“This raise isn’t just about fuelling growth; it’s about accelerating a new phase of legal innovation.”

From legal tools to digital lawyers

As legal workloads increase in volume and complexity, Plexus’ AI-powered platform is evolving beyond workflow automation into digital lawyers that empower business teams to operate with unprecedented speed, efficiency, and impact.

The platform is already used by household brands like Nike, L’Oréal, PepsiCo, Woolworths, AIA, and The Iconic to streamline everything from contract review and negotiation to compliance workflows and approvals.

“This is just the beginning,” Mellett said. ​“We’re building the platform in-house legal teams didn’t know they needed, but won’t be able to live without.”
