Dave Haase knew the calculus had stopped making sense somewhere around his third tax season watching preparers hunt-and-peck data from crumpled W-2s into software built in the 1990s. A partner at his own accounting practice in California, Haase—CPA, Stanford MBA, the whole credentialed package—started building prototypes on nights and weekends. Not to automate his clients away. To give his team back their weekends.
That side project became Juno, and on April 9, 2026, the Rancho Santa Fe-based startup announced it had raised $12 million in seed funding led by Bonfire Ventures, with Impression Ventures and Xfund joining the round. Eight months after launch, the company reports mid-seven-figure annual recurring revenue and a client base approaching 500 tax firms. Haase, for his part, says he sold Golden State Accounting in 2025 to bet full-time on the premise that AI could do the drudgery—but shouldn't be trusted to file your taxes unsupervised.
It's a nuanced position in a market that's split between legacy software giants pouring billions into automation and buzzy AI agents promising to file your 1040 while you sleep. Juno, operating legally as TruePrep Inc., sits somewhere in between: a layer of AI tooling designed to slot into the existing workflow of professional preparers, not replace the humans—or the entrenched software—entirely.
Three Modules, One Thesis
The product breaks into three pieces. Preparer handles document ingestion—92 form types, from W-2s to the notoriously fiddly K-1 schedules—and generates workpapers. Reviewer cross-checks for errors and flags discrepancies against prior-year returns. Advisor runs tax-planning scenarios, the kind of what-if modeling that firms bill separately but rarely have bandwidth to deliver during crunch time.
All of it integrates with the incumbents: CCH Axcess, Lacerte, UltraTax CS. Juno doesn't want to be the next TurboTax. It wants to be the unglamorous middleware that makes tax professionals 30% faster without retraining them on entirely new software. Co-founder Jack Flitcroft, who leads AI development, built the extraction engine to handle documents that arrive as PDFs scanned at gas stations, photos taken under fluorescent lights, faxes that have been faxed twice.
Pricing runs per return—roughly $45 at the low end, dipping into the low $30s for high-volume shops. There's also a $4,000 package covering up to 100 individual returns, and a seven-day trial that includes five freebies to test the system mid-season. Business returns—1120s, 1120-S forms, partnership 1065s—are listed as "coming soon" on the company's site, a tacit acknowledgment that corporate tax is a different beast entirely.
A Market Already Consolidating
Juno enters a landscape where Thomson Reuters has spent the past few years writing checks with a lot of zeroes. The company paid $500 million for SurePrep in 2022, then another $600 million for SafeSend in January 2025—bets that automation would become table stakes for professional tax software. Meanwhile, consumer-facing AI is creeping in from the other direction: Perplexity unveiled its own tax agent in April 2026, aimed at individuals willing to trust an algorithm with their refund.
Haase's pitch is that professional firms won't—and shouldn't—hand over the keys entirely. "We're not trying to replace the CPA," he said in a recent interview, though the company declined to make him available for this story. "We're trying to replace the part of the job nobody went to grad school for."
It's a familiar refrain in enterprise AI, this promise of augmentation over automation. Whether firms buy it may depend less on the technology than on how badly they need warm bodies during tax season. Accounting has a staffing crisis—burnout is rampant, new grads are choosing consulting over compliance, and busy season still means 70-hour weeks in many shops. If Juno can shave even a few hours off each return, the ROI writes itself.
Scaling Integrations, Chasing Volume
The fresh capital will fund product expansion and deeper hooks into the broader accounting software ecosystem. Juno has already inked partnerships with TaxDome, a practice management platform, in July 2025, and announced a partnership with K1x, which handles partnership tax data, in January 2026. Bonfire Ventures partner Jim Andelman pointed to the firm's vertical AI thesis—backing tools purpose-built for specific professional workflows—as the rationale for leading the round.
What's less clear is how Juno navigates the business return roadmap. Individual 1040s are relatively standardized; corporate and partnership filings are labyrinthine, state-specific, and politically loaded. Getting that right may determine whether Juno stays a niche productivity tool or becomes infrastructure that accounting firms can't imagine working without.
For now, the company seems content to own the boring middle: not the cutting-edge consumer chatbot, not the billion-dollar suite from Thomson Reuters. Just software that lets a CPA leave the office before midnight in March. In tax tech, perhaps that's revolutionary enough.
