# Jin Chang

> Jin Chang is the CEO and Co-Founder of Fieldguide, the leading AI platform for audit and advisory firms. A former EY practitioner and CPA, he tried to leave accounting multiple times before founding Fieldguide in 2020, channeling firsthand frustration with clunky tools into a $700M-valued company now serving half of the top 100 U.S. CPA firms. With $125M raised - including a $75M Series C from Goldman Sachs in February 2026 - Chang is rewriting how accountants work at a moment when the profession faces an existential talent crisis.
