Melbourne-based legal tech company Isaacus has raised US$700,000 in a pre-seed funding round to help bring its products to market.
The funding round was jointly led by Aura Ventures and Galileo Ventures.
The company plans to provide specialized legal AI models to legal tech companies like Harvey, Robin AI, AccuFind Law, and SprintLaw, offering a more focused alternative to general AI models.
Isaacus has created a large, proprietary Blackstone Corpus (named after an 18th-century English legal expert) that includes laws, regulations, cases, and other legal information from the US, UK, Canada, Australia, New Zealand, Ireland, the EU, and the United Nations.
Founder Umar Butler is a data scientist and legal tech expert. He previously served as the assistant director of data science at the federal Attorney-General’s Department, where he created the department’s data science unit and managed all national AI projects.
Isaacus said it is “releasing models directly to legal tech companies via a public API”, with a “small group of industry design partners” supporting development. It is also consulting with non-legal AI companies, law firms and other large enterprises that might require “sovereign legal AI capabilities”.
“Isaacus is building the core AI infrastructure for legal — what AWS became for the cloud, Isaacus aims to be for law,” Aura Ventures partner Mark Esterhuizen said.
Meanwhile, Galileo Ventures general partner James Alexander said, “We want to be the first to support the next generation of legal service providers through the delivery of best-in-class foundational legal LLMs.”
At Isaacus, the team has many years of experience in law, AI, and system design. This expertise is essential because the legal field is changing quickly, and only experts with knowledge across different countries can build the important infrastructure the industry needs.
The startup is also providing its AI models to legal tech companies through a public API. Additionally, it works with non-legal AI companies and large businesses that need specialized legal AI tools and the know-how to use them effectively.
Buter said Isaacus will soon release a new generation of legal embedding and generative models designed to outperform everything currently in use by legal tech practitioners.
