San Francisco-based tax automation startup Juno has officially announced the completion of a $12 million seed funding round. The round was led by Bonfire Ventures, with participation from Impression Ventures and Xfund.
Juno was founded in 2023 by veteran CPA Dave Haase. After running his own accounting firm in the San Francisco Bay Area for years, Haase recognized the industry was on the cusp of a technological shift as he witnessed the potential of AI in tax preparation. "My business was either going to go under in 18 months or it was going to transform using these tools," Haase said.
AI as an Assistant, Not a Replacement
The accounting industry has long been bogged down by manual data entry, with small-to-medium-sized firms holding roughly 90% of the market share. Haase notes that Juno’s core philosophy is to let AI handle the heavy lifting of data entry while leaving decision-making to human accountants. He emphasizes that tax filing has zero margin for error, and current AI technology cannot independently handle complex tax calculations with 100% accuracy.
"Tax filing isn't a multiple-choice test. If you’re only 99% accurate, that’s a failure for the client and could result in penalties," Haase explained. Juno acts as a bridge between a client’s raw documents and accounting software, automatically identifying and inputting data from over 90 document types—including IRS forms—slashing the time required for a filing from two or three hours down to just seven to ten minutes.
Since launching its AI copilot feature in 2024, Juno has amassed nearly 500 clients. Although still in its early stages, Haase revealed that the company has reached mid-seven-figure annual recurring revenue in just eight months. Currently, Juno charges on a per-filing basis, with costs ranging between $30 and $45 per return.
Jim Andelman, co-founder and managing director at Bonfire Ventures, stated that they invested in Juno because the team has precisely identified a major industry pain point. Andelman believes that tax preparation is a field built on trust, and by utilizing a "human-in-the-loop" model, Juno improves efficiency while maintaining the auditability and transparency of the process.
As AI continues to permeate the fintech sector, global venture capital support for the industry has grown steadily. According to Crunchbase data, total global funding for fintech startups reached $53.8 billion in 2025, a more than 29% increase from the $41.6 billion recorded in 2024.
Haase plans to expand the company's customer base by launching products tailored for corporate tax filings in the near future. He reiterated that Juno’s goal is not to replace accountants, but to liberate professionals from basic data entry so they can return to their primary role: providing expert tax advice.
