Blue J, a generative AI-powered research platform tailored for tax and legal professionals, announced Monday that it has raised $122 million in a Series D funding round. The infusion will fuel team expansion, product innovation, and a sharpened marketing push as the company eyes global growth.
The funding round was spearheaded by Oak HC/FT, a venture firm specializing in healthcare and fintech, and Sapphire Ventures, an investor known for scaling B2B software giants. Other participants included Intrepid Growth Partners, as well as returning backers Ten Coves Capital and CPA.com.
“This commitment is a powerful endorsement of our vision to transform tax research,” said Benjamin Alarie, Blue J’s CEO and cofounder. “With this capital and industry support, we will accelerate innovation and deliver even greater value to professionals. We are building the future of tax. This is just the beginning.”
From Cumbersome to Cutting-Edge
Founded in 2015, Blue J markets its AI tax research platform to accounting firms, law firms, corporations, and government agencies. Powered by OpenAI’s latest models, the software synthesizes decades of tax rulings across the U.S., Canada, and the UK to answer complex tax questions in minutes rather than hours.
“Tax research has long been a time-consuming burden,” said Allen Miller, partner at Oak HC/FT. “Blue J has cracked the code with a solution that accelerates research while raising accuracy. We believe Blue J will become the new standard for resolving complex tax questions.”
Sapphire Ventures partner Cathy Gao, who is joining Blue J’s board, praised the company’s trajectory: “By applying generative AI to decades of rulings, Blue J is already trusted by enterprise clients and embraced by top firms. The momentum proves the industry is ready, and Blue J is building the operating layer for global tax cognition.”
