Auckland-based legal and tax AI company Nylon, formerly Law Cyborg, has opened a Seed funding round seeking $20 million to accelerate growth in the United Kingdom and prepare its product for the United States market.
Founded by former EY and EY Law tax lawyer Andrew Wierda, (pictured) Nylon provides AI-powered tax and legal research for accountants, lawyers and other professional advisers. The platform is now used by close to 2,000 firms across New Zealand, Australia and the United Kingdom, including two members of the Big Four.
The proposed funding round will support further expansion in the UK and the development of a US-focused product—markets Nylon identifies as its most significant international opportunity.
“New Zealand investors backed us early and have been hugely supportive,” said Wierda, Nylon’s co-founder and chief executive.
“As we take on global incumbents, we are also looking to bring in international investors with deep knowledge of the UK and US markets—people who can help us scale with real speed and ambition.
“AI is fundamentally changing how lawyers and accountants work around the world. We want to build the technology they use and trust every day.”
Nylon’s 25-person team is predominantly based in Auckland. Wierda said the company remained committed to retaining its development capability in New Zealand while expanding internationally.
“There is a genuine opportunity to show that a New Zealand company can compete with the biggest names in legal and tax research,” he said. “Building globally relevant technology here, while growing offshore, matters to us.”
The rebrand from Law Cyborg to Nylon reflects a wider ambition: to become a core part of the professional infrastructure relied upon by trusted advisers.
“Like nylon in the equipment relied on by the world’s best mountaineers, we want to become the dependable material behind the work of the world’s best advisers,” Wierda said.
From in-house tool to international platform
Wierda developed the original product while working as a tax lawyer at EY Law, frustrated by the limitations of existing research tools. After registering a domain and building an early version for his own work, he began signing up external firms.
Following early traction with approximately 40 firms, the company raised an angel round in 2024 led by former M-Com chief executive Adam Clark. Other investors included K1W1, King’s Counsel Michael Heron, PwC veteran Geof Nightingale and entrepreneur Serge van Dam.
In 2025, the company raised $2 million in pre-seed funding from Australasian venture-capital firm Blackbird. It subsequently established a dedicated Auckland office, expanded its team and broadened the platform from tax research into employment law.
Nylon expanded into Australia and the United Kingdom in 2025 with its tax-law product and now covers all areas of New Zealand and Australian law.
New meeting bot targets advisory risk
Alongside the Seed round, Nylon has launched an AI meeting bot for accounting and legal client meetings.
The tool is designed to operate as an issue-spotting note-taker. Rather than simply transcribing a discussion, it analyses the substance of the conversation, identifies potential tax, compliance or legal risks, and delivers a summary to participants after the meeting.
“Most note-taking tools record what was said,” Wierda said. “Ours is designed to understand the substance of the discussion.
“If it identifies something that may not be right—a tax exposure, compliance issue or overlooked risk—it flags it. It is intended to be like having a sharp junior in every meeting who does not miss a detail.”
Nylon says its AI is constrained to a defined collection of trusted material, including legislation, case law, tax materials and government sources. Answers include in-text citations and a confidence score, allowing professionals to assess and verify the underlying authority rather than rely on an untested general-purpose AI response.
Wierda is scheduled to meet prospective investors in San Francisco, New York and London in the coming weeks.
