Fieldguide Raises $75M in Series C for AI-Native Audit Platform

There is a certain smell to real momentum. It is not hype or hope or a polished deck passed around a boardroom like a peace pipe. It smells like deadlines, liability, and the quiet confidence of people who know the numbers have to balance when the lights are on and the regulators are watching. That is the air around Fieldguide right now. San Francisco-based. Accounting-born. Software raised in the wild. And this week, walking out of the market with a Series C that feels less like a funding round and more like a statement of intent.

Fieldguide did not come up through vibes. It came up through audits. Founder and Chief Executive Officer Jin Chang learned early that trust is built line by line, not with slogans. After earning a BS from USC and an MBA from UC Berkeley, Chang cut teeth at EY, deep inside the machinery of assurance, risk, and compliance. While still in grad school, Chang founded Lydia Tax, a cryptocurrency tax automation platform, long before crypto accounting became dinner-table conversation. That instinct shows up here. Fieldguide was built for firms that live on accuracy, not applause.

The Series C lands with backing from Point72 Ventures, Global Founders Capital, DNX Ventures, Fourth Realm Ventures, and others who tend to bet when the math is boring and the upside is not. The product reflects that discipline. Fieldguide replaces the chaos of spreadsheets, emails, and manual review with an AI-driven workflow platform purpose-built for audit and advisory firms. It runs on AWS, built with GraphQL and React, and carries security credentials like ISO and EU AI Act compliance because accounting firms do not get second chances with client data.

The traction is not theoretical. Firms like Baker Tilly, RSM US LLP, CohnReznick, Cherry Bekaert, and Cohen & Co are already running real engagements through the platform. Fieldguide’s field agents are posting error rates under one percent compared to manual processes. That is not a demo metric. That is the difference between confidence and cleanup. It is why CPA Practice Advisor has named Fieldguide a top firm technology five years running, and why Accounting Today keeps putting Jin Chang on every influential list it prints.

Then there is the KPMG signal. Announced October 23, 2025, KPMG entered as both strategic partner and minority investor, with leaders like Thomas Mackenzie and Brian Fields stepping into the collaboration. In a conservative industry, partnerships move slowly. When they move, they mean something. This one says Fieldguide is not just selling software to accounting. It is being invited into the operating system.

Fieldguide is a clever name. Guides are supposed to know the terrain, carry the weight, and get you there without drama. This raise suggests the market agrees. The question now is not whether accounting firms will modernize. It is who they will trust to walk them through it when the stakes are real and the clock is running.
