Australian legal AI firm raises $700,000

Australian AI research and development company Isaacus has completed its pre-seed round, raising $700,000 from Australian tech VCs Aura Ventures and Galileo Ventures.

Isaacus builds specialised AI models for legal tech firms, with its core offering including a soon-to-be-released legal embedding model as well as a legal grounding API, in addition to its already-in-use lightweight legal classification and text extraction models.

The Isaacus team consists of Umar Butler, his brother Abdur-Rahman Butler, and his father Anthony Butler.

Umar Butler was previously the assistant director of data science at the Attorney-General’s Department, where he was responsible for overseeing national-level AI projects.

Abdur-Rahman Butler is an economist by education and data scientist by trade, while Anthony Butler has served as CTO of IBM MEA and a senior advisor to the Saudi Central Bank, as well as currently working as chief architect of Humain, Saudi Arabia’s sovereign AI company.

"Our core mission is to solve every one of the common AI- and data-related pain points of the legal tech industry, whether by delivering superior legal research capabilities that cut far above and beyond those of general-domain retrieval models or by providing direct access to enormous amounts of high-quality legal data from the Blackstone Corpus, our proprietary, living, multijurisdictional repository of legal knowledge," the company claims.

"Eventually, we see ourselves becoming the legal data and AI infrastructure that powers all the world’s leading legal tech solutions."
