Cranston is a team of engineers and accountants in San Francisco. We build AI that runs the back office for CPA firms: tax prep, bookkeeping, and the client follow-up in between. Some firms run our software with their own staff; others hand us the work entirely.
Why Cranston exists
Most of the work that eats a firm's week doesn't need a CPA. It needs a system.
Firms lose their best hours to data entry, document collection, and cleaning up offshore handoffs — production work that pulls licensed people away from the judgment clients actually pay for. Cranston was built to take that work over: agents do the prep and the chasing, and every judgment call stays with a licensed reviewer.
The company comes from both sides of the problem — people who have built production AI systems and people who have spent their careers inside accounting firms. CPA firms run live client work through Cranston every day.
The goal is simple: firms take on more clients without taking on more headcount, and spend their time on the work clients actually pay them for.
Work with us
We're in San Francisco, building with AI agents from day one. What you ship reaches live firm work quickly, and the bar is set by people who have spent their careers in this industry. If you like hard problems in tax, bookkeeping, and firm operations, we want to meet you.
