A Fast-Growing Legal Tech Powerhouse
Blue J now employs over 80 staff members and serves tens of thousands of tax professionals across thousands of organizations. The company’s valuation following the Series D round was not disclosed, though the investment comes less than a year after its last financing in December.
The broader legal tech industry has surged in parallel: investment in legal technology companies jumped 44% year-over-year to $3.56 billion in the first half of 2025. AI-focused platforms have been at the forefront of that boom, including legal AI assistant Harvey, which recently secured $300 million Series D and Series E rounds, reaching a $5 billion valuation.
Blue J’s executives say the new funding marks not just a financial milestone but a pivotal moment in the evolution of AI-driven tax research—a sector where speed, accuracy, and trust are paramount.
