Blue J raises $176m Series E to put AI agents on tax work

10 November 2026: Blue J, a Toronto company that sells AI tax research to accountants and law firms, says it has raised US$176 million in a Series E round led by JMI Equity. The company says the round values it at more than US$700 million, or more than C$1 billion, and that the money will go into Workflows, its agentic product, and into expansion in the United Kingdom and beyond.

Who put money in

JMI Equity, a growth investor with offices in San Diego, Washington and Baltimore, led the round. Existing investors Oak HC/FT and Sapphire Ventures took part, as did Intrepid Growth Partners. Jack Duane, a principal at JMI, joins Blue J's board.

"We believe Blue J has built the best research platform in the market," Duane said in the announcement.

BetaKit reports that the round includes a secondary component, with some existing shares sold, and that the Series D about 15 months earlier was US$122 million. Blue J's own release does not give the size of the secondary part.

From answering questions to doing the work

Blue J built its name on a research engine that it says has answered more than 14 million tax questions. Workflows is the step after that: rather than return an answer, it takes on a piece of work. The tasks the company names are reviewing returns before filing, preparing responses to IRS notices, analysing partnership, LLC and trust agreements, assessing multistate nexus, and drafting client communications.

The output comes with its supporting sources and the steps the workflow took, so a practitioner can check it before signing off. "We're building toward a world in which every tax professional has a team of AI agents at their side," said Benjamin Alarie, chief executive and co-founder.

The pitch is aimed at the part of tax work that is billable but repetitive. A return review or a nexus assessment follows a known pattern, which is the kind of task a firm can hand to software while keeping the judgment calls with a person.

The growth the company reports

Blue J says annual recurring revenue grew 165% in the 15 months after its Series D. It counts more than 6,500 organisations and more than 45,000 tax professionals as users, including Big Four firms and Fortune 100 companies. The team doubled over the year, and the company expects to pass 200 employees by the end of 2026.

In October Blue J agreed to put its tax research inside Legora, an agentic platform for legal work that it says more than 140,000 legal professionals use.

The company was founded in 2015 by Alarie, chief technology officer Brett Janssen, Anthony Niblett and Albert Yoon, according to BetaKit.

Where it sits among tax tools

Most of what we list for tax departments handles filing and practice administration rather than research. Our tax practice management software category lists 16 products, our sales tax software category 15 and our corporate tax software category seven, alongside 12 in legal research software.

The UK expansion is the part of the plan with no detail yet: Blue J has not said when it will open there or which tax regimes its research will cover first.
