Toronto’s Blue J Legal raises $176-million to expand AI offerings to tax professionals

Rapidly growing Toronto AI software company Blue J Legal Inc. has secured a nine-figure financing for the second straight year as it prepares to offer agentic products to its clientele of tax specialists.

The University of Toronto spinout led by tax law professor Benjamin Alarie has raised a US$176-million financing led by Baltimore-based JMI Equity. U.S. financiers Oak HC/FT and Sapphire Ventures, which co-led a US$122-million investment into Blue J last year, are participating, as well as past backer Intrepid Growth Partners, a Canadian AI-focused investor. The deal, set to be announced Tuesday, values Blue J at US$700-million.

Nearly US$100-million will go to buy shares from employees and early investors. Blue J plans to use its $80-million in proceeds to commercialize its nascent agent product and expand in the U.K. – its third market after the U.S. and Canada – and globally.

Blue J’s main clients are tax accountants, though it also sells to tax lawyers, making it one of several companies bringing AI-driven products to law firms to hasten the automation of often tedious, time-consuming work.

Mr. Alarie, a past associate dean of U of T’s faculty of law, founded Blue J in 2015 with fellow professors Albert Yoon and Anthony Niblett. They worked to develop AI software that would help lawyers and accountants speed up the process of researching complex taxation matters, powered by predictive analytics software. Blue J raised venture capital and generated modest sales.

Then in late 2022 OpenAI launched ChatGPT, the AI chatbot that answered text questions in seconds. Mr. Alarie realized Blue J could fold generative AI capabilities into its product to answer far more tax-research questions. “The technology wasn’t really there to allow us to create a system that could answer any arbitrary tax research question – until we saw the promise of LLMs,” he said.

Blue J rebuilt its product incorporating OpenAI’s large language models, relaunching it in mid-2023. The updated version produced answers in about 90 seconds, but they were wrong about half of the time, a by-product of the quirky tendency of LLMs to generate incorrect information.

The Toronto company set about refining its product, in part by licensing data from Tax Notes, a leading publisher of tax views and commentary, and benefiting from improvements to successive releases of LLMs. Many of its answers come from content licensed by several tax data and information providers, some in exclusive deals.

By the end of 2024, Blue J could produce answers within 10 seconds that were 95-per-cent-plus accurate and its users could have technical back-and-forth conversations about complex tax matters with the program. Some companies found users could save two hours a week each using Blue J, whose individual plans start at US$1,498 a year.

Mr. Alarie said error rates have come down by about 80 per cent this year as measured by “down votes” from users in response to its generated answers, which now occur 0.05 per cent of the time. “We can now confidently deliver an answer to just about any tax research question,” Mr. Alarie said.

Blue J’s increasing speed and accuracy spurred interest, and the number of client firms mushroomed from less than 100 three years ago to more than 1,000 at the end of 2024 and 4,000 a year later. It now serves more than 6,500 firms. Blue J’s annual recurring revenue has expanded by 165 per cent since its last financing in August 2025 and is now in the mid-eight-figure range.

JMI principal Jack Duane said his firm tracked Blue J for years, and received “resounding positive sentiment” when it spoke to its customers, “not just around Blue J’s technology and research platform but also around the company and team. What came through clearly is they are a trusted AI vendor in a space where trust is of the utmost performance.”

Asked of the competitive risk, including the threat that the LLM giants themselves will move into the space, Mr. Duane responded that Blue J’s offering is “extremely hard to replicate” due to its access to proprietary data “and most importantly, their unique domain expertise.”

JMI is one of the most successful foreign investors in the Canadian tech sector. Its portfolio here includes stakes in Clio, Pointclickcare, Jane, Safe Software and Benevity.

Blue J is close to launching its agentic offerings, which will expand its utility beyond simply generating tax answers to clients. Its new workflow product will also enable them to automatically draft other work using its answers, including memos and notices of assessment. “Blue J will be increasingly capable of assisting with just about any of those advisory workflows for which research is an essential input,” Mr. Alarie said.
