Blue J Announces US$176 Million Series E to Put AI Agents to Work for Tax Professionals

Led by JMI Equity, the round values Blue J at more than US$700 million after a year of 165% growth in annual recurring revenue

‍Toronto – November 10, 2026 – Blue J, the leading tax research and advisory platform, today announced it has raised US$176 million in Series E capital led by JMI Equity, a leading growth equity investment firm. Existing investors Oak HC/FT and Sapphire Ventures also participated in the round, along with Intrepid Growth Partners. The round values the company at more than US$700 million (more than C$1 billion). Blue J will use the new capital to scale Workflows, its agentic AI for tax work, and to expand in the United Kingdom and internationally.

“An answer is rarely the end of a tax professional’s job. It’s the beginning of the work a client needs done,” said Benjamin Alarie, CEO and co-founder of Blue J. “We’re building toward a world in which every tax professional has a team of AI agents at their side, able to carry that work, under their direction, from the client’s first question to the finished partner-ready deliverable. That frees professionals to spend their time where they’re irreplaceable: on judgment, strategy and their clients. JMI sees the same future, and we’re excited to have them lead this round.”

Workflows builds on the research engine that has answered more than 14 million tax questions. With it, tax professionals can hand Blue J the work itself: reviewing returns before filing, preparing IRS notice responses, analyzing partnership, LLC and trust agreements, assessing multistate nexus and drafting client communications. The output is partner-ready, with supporting sources and workflow steps available for inspection. Practitioners review the work and make the judgment calls.

“JMI is focused on partnering with AI innovators who deliver unique value for specific markets. Blue J has done exactly that for tax,” said Jack Duane, Principal at JMI Equity. "We believe Blue J has built the best research platform in the market and we are looking forward to supporting the next chapter of their growth." As part of the investment, Jack Duane will join Blue J’s Board of Directors.

The round follows a year of rapid growth. Annual recurring revenue grew 165% in the 15 months after Blue J’s Series D, and more than 6,500 organizations now use Blue J, including Big Four firms and Fortune 100 companies. The company has doubled its team over the past year and expects to exceed 200 employees by year-end. In October, Blue J partnered with Legora to bring its tax research into Legora’s agentic operating system for legal work, which is used by more than 140,000 legal professionals.
