About Cranston

Cranston AI is a seed-stage AI company headquartered in San Francisco with a mission to transform how CPA firms operate by automating bookkeeping and tax preparation, enabling accountants to focus on higher-value advisory work. Founded by two best friends with proven entrepreneurial track records, the company is led by a CEO who previously built and scaled a B2B SaaS company to over $10M in revenue and $25M in funding from top-tier investors like Index Ventures and Founders Fund, while co-founder Max scaled a tax and bookkeeping business to millions in revenue. The founding team of four includes the two co-founders and two part-time CPAs who bring deep domain expertise to the problem they're solving. Despite being early-stage, Cranston AI has already demonstrated strong market traction by signing hundreds of thousands of dollars in pilot revenue in recent weeks, validating demand for their solution among accounting firms.
