Blue J, a leading GenAI tax research platform, secured $122 million in Series D funding. Oak HC/FT and Sapphire Ventures led this investment round. Intrepid Growth Partners, Ten Coves Capital, and CPA.com also participated. This Series D round follows the company's Series C seven months prior.
The Toronto-based company will use the capital to accelerate team expansion, product development, and market reach. Blue J's platform leverages advanced generative AI to provide instant answers to complex tax questions. It covers U.S. federal, state, local, Canadian, and UK tax law. Unlike traditional tools from providers like Thomson Reuters, Blue J offers a conversational interface.
Accelerating AI Tax Research
Blue J doubled its revenue and customer base in the first half of 2025.
The platform now serves tens of thousands of tax professionals across thousands of organizations. Over 70% of users log in weekly. Since January 2025, Blue J has grown to over 80 employees. Its new customer acquisition rate has also doubled. This Series D investment positions the company as a key player in the evolving fintech and legal tech sectors, differentiating itself from competitors such as LexisNexis.
