Cranston AI - AI-powered accounting, built like a product company.

Cranston is a full-stack AI accounting firm. We replace traditional accounting labor with autonomous AI systems, supervised by licensed CPAs. Most tools in this space either sell software to accountants or layer chatbots on top of spreadsheets. We built the accounting firm itself — end to end — so we can automate the work directly and guarantee accuracy.
