How Juno is Scaling an AI Tax Preparation Platform that Automates 90% of Busy Work

Juno, the tax prep automation platform built by CPAs for tax professionals, led by Dave Hasse, has announced $12 million in seed funding led by Bonfire Ventures, along with Impression Ventures and X Fund. 

Juno automates tax return preparation, review, and advisory workflows, reducing time spent per return by up to 50% while keeping humans actively involved in the process.

Tax preparation remains highly manual, while opaque AI tools introduce unacceptable risk in regulated environments.

Juno bridges this gap by automating repetitive work while preserving human oversight, enabling firms to increase throughput and focus on higher-value advisory tasks.

Juno introduces a “clear box” approach to tax automation, combining efficiency with full transparency. By enabling source-to-return traceability and keeping practitioners in the loop, it ensures every data point can be verified while automating the majority of manual entry.

The platform processes data in real time, integrates across a wide range of document types and tax tools, and flags inconsistencies for review, turning tax preparation into a faster, audit-ready workflow without removing professional oversight.

Juno was founded by David Haase, who built and operated a large accounting practice, where firsthand experience exposed persistent inefficiencies in tax workflows. The platform was developed and refined within that environment before being scaled with a team of AI, accounting, and tax specialists.

This operator-led approach reflects deep domain insight, with a focus on solving real bottlenecks while meeting the high standards of accuracy and accountability required in tax work.
