Toronto-based Blue J, a generative AI platform for tax research, has raised $168 million in Series D funding, just seven months after closing its Series C round.
The round was led by Oak HC/FT and Sapphire Ventures, with participation from Intrepid Growth Partners and existing investors Ten Coves Capital and CPA.com.
The funding underscores Blue J’s rapid rise as the frontrunner in AI-powered tax research. CEO and co‑founder Benjamin Alarie said the investment validates the company’s vision to transform the way professionals navigate complex tax laws.
“Their commitment is a powerful endorsement of our vision to transform tax research,” said Alarie. “With this capital and industry support, we will accelerate innovation and deliver even greater value to tax professionals. This is just the beginning.”
Blue J’s platform uses advanced generative AI to provide instant, source‑cited answers to tax questions across U.S. federal, state, and local tax (SALT), as well as Canadian and U.K. tax law. Its conversational interface eliminates the need for traditional keyword-based research, enabling users to find authoritative answers in seconds.
The company has seen rapid adoption, with more than 70% of users logging in weekly and a Net Promoter Score in the mid‑70s. Revenue and customer base more than doubled in the first half of 2025, with tens of thousands of tax professionals now relying on Blue J.
With its new funding, the company plans to expand its team, accelerate product development, and scale market reach as it positions itself to become the standard for AI‑driven tax research amid rising global tax complexity.
