About Cranston AI

Cranston AI is building AI-native software for accounting.

Accounting is still full of fragmented tools, spreadsheets, manual review, and repetitive judgment calls buried inside email threads and close checklists. We are building systems that help accounting teams turn source documents, transactions, reconciliations, and review workflows into cleaner financials with far less manual drag.

We work in one of the biggest, least modernized professional services markets. The work is messy, high-stakes, and deeply operational, which is exactly why AI matters here. The right product does not just summarize documents or draft emails. It understands accounting context, preserves auditability, and helps professionals move faster without losing control.

We are a small team moving quickly on a hard problem: making accounting firms dramatically more scalable with AI.
