What Juno Is
Juno is a San Diego-based AI tax preparation platform built specifically for underserved SMB accounting firms — the segment that sits between TurboTax-style self-prep tools and expensive enterprise software used by the Big Four. The platform automates roughly 90% of data entry across tax returns so accountants can focus on review and advisory work.
How It Works
Juno ingests more than 90 document types — W-2s, 1099s, K-1s, broker statements, and a wide range of supporting paperwork — and uses AI to extract, classify, and reconcile data against prior-year returns. The system flags inconsistencies and prior-year changes for human review, shrinking what is typically a 2-3 hour preparation process to 7-10 minutes per return.
Founders and Team
Juno was founded in 2024 and is headquartered in San Diego, California. The company is purpose-built around the SMB accounting firm segment, a market that has historically been ignored by both consumer tax software vendors and enterprise tax suite providers.
Funding and Traction
Juno raised a $12M seed round in April 2026 led by Bonfire Ventures, with Impression Ventures and Xfund participating. In just eight months the company reached mid-seven-figure ARR, with about 500 accounting firms on the platform expected to process roughly 100,000 returns in 2026.
Differentiators
Juno's per-return pricing — starting around $45 and dropping to the low $30s for high-volume firms — undercuts traditional enterprise tax suites while offering automation depth that consumer tools cannot match. Its document coverage (90+ types) and prior-year reconciliation are the core differentiators.
