“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, in a statement. “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, which was released last month, builds on the research engine that lies at the foundation of Blue J and adds agentic capacities to the mix, allowing it to not only provide answers but execute tasks. The solution combines a client’s context with Blue J’s tax research to produce structured drafts ready for review. Users can do things like turn a completed 1040 into a client-ready email explaining what changed and how carryovers and limitations shaped the tax due, turn a dense partnership agreement into a cited memo that supports filing positions, or turn a federal or state tax notice into a draft response letter, with clear next steps for your review.

Specific workflows are listed within the Blue J app itself with names such as “1065 Technical Review” or “Automatic Relief for Late S Corp Election.” They are activated with a “start workflow” button. In the end, practitioners review the work and make the judgment calls.

The announcement follows a year of rapid growth. Annual recurring revenue grew 165% in the 15 months after Blue J’s Series D round. 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 as well.
