Juno (TruePrep AI) raises $12M seed to automate tax-return prep with a 'clear box' AI

What's the deal? San Diego-based Juno has raised $12M in seed funding to scale its AI platform that automates tax return preparation for accounting firms.

The platform automates up to 90% of data entry across more than 90 document types, while keeping human accountants in control of the process. Juno says it can cut preparation time by up to 50%.

Why now? Tax preparation remains stubbornly manual, often requiring practitioners to input thousands of data points by hand. AI has emerged as an obvious fix, but many firms worry about accuracy and accountability in fully automated systems.

Juno calls its approach a "clear box" system — every data point is traceable from source to return, so users can verify exactly how the AI processed their information. The platform also flags errors, inconsistencies, and prior-year changes automatically.

"We didn't just build Juno to save time; we built it to allow accountants to move from being data processors to the high-value advisors their clients actually need," said founder and chief executive David HaaseDealroom has a profile for this one. Try Dealroom →.

What could go wrong? Tax software is a crowded market, and Juno faces competition from incumbents and other AI startups racing to automate accounting workflows. Convincing risk-averse firms to trust a new platform with sensitive financial data is no small task.

The "human-in-the-loop" pitch also cuts both ways: it reassures cautious adopters but could limit the efficiency gains that fully automated competitors promise.

The signal: Juno reflects a broader pattern in enterprise AI — products that augment professionals rather than replace them are finding traction in regulated industries. Hundreds of tax firms already use the platform, reportedly doubling their efficiency.

Haase previously built Golden State Accounting into a regional firm handling thousands of returns, giving him firsthand knowledge of the bottlenecks Juno targets. The seed round suggests investors see room for AI tools that prioritise transparency and compliance over full autonomy — a bet that cautious, regulation-heavy sectors will adopt AI faster when humans stay in the driver's seat.
