FifthFirm

Our Story

We built the firm that
should have existed.

The Big 4 — Deloitte, PwC, EY, KPMG — serve the Fortune 500 at $300–500 per hour. That leaves 45,000 CPA firms and 6 million mid-market businesses without access to world-class accounting, advisory, and audit capabilities.

FifthFirm changes that. We use AI to deliver Big 4-quality professional services at a fraction of the cost — not by cutting corners, but by automating the 80% of work that doesn't require human judgment, so professionals can focus on the 20% that does.

Mission

Democratize professional services. Every business deserves access to the same quality of accounting, tax, and advisory that Fortune 500 companies receive.

Approach

AI-assisted, human-reviewed. Our 110+ specialized AI agents handle the heavy lifting. Licensed professionals review every output. You get speed and accuracy.

Difference

We learned from Botkeeper's failure. Pure AI doesn't work for financial services. The winning model is AI that makes professionals faster, not AI that replaces them.
