Accountants still request bank statements over email, reconcile accounts manually, and type tax data line by line. The average accountant spends 70% of their time on repetitive tasks.\n\nIt’s a nightmare, and it’s a waste of company time and resources.\n\n# **Our Story:**\n\nFor the last 5 years, We have been obsessed with this problem from opposite ends. Sean was the CTO of ReMatter, a vertical ERP for scrap yards. ERPs are notoriously gnarly to build, sell, and implement. But companies using their ERP would have an average of 4 back-office employees doing data entry, reconciliation, AR/AP, and reporting on top of the ERP.\n\n_For every $1,000 companies spend on their ERP, they spend $50,000 on labor managing it._ \n\nMax spent five years running a profitable accounting firm in the weeds doing exactly that work: reconciling, filing, and cleaning messy accounting data for thousands of companies.\n\n_And in a few years, it will all be automated with AI._\n\nWhile we were working on these separate companies, we met at the same hole-in-the-wall Mexican spot twice a week, arguing about AI models, Ben Thompson essays, and of course, accounting.\n\n![uploaded image](/media/?type=post\u0026id=94434\u0026key=user_uploads/450932/68683d81-ed74-4108-8a12-4736b192cb2f)\n\nThree months ago over a couple plates of tacos, we decided it was time to drop what we were doing, move to San Francisco, and start Cranston, the AI Accounting Company.\n\n![uploaded image](/media/?type=post\u0026id=94434\u0026key=user_uploads/450932/e38affa2-953c-4a5f-a446-e77b01ecadc4)\n\nMexican restaurant ——\u0026gt; YC\n\n# The Solution:\n\nOur agentic workflows are built from the ground up to think like a human accountant with the context of your business. Accounting is just a system of rules and judgment calls that put the right information in the right place at the right time.\n\nOur system: \n\n* Pulls in your company documents and context to create a relational map of your company data\n* Reconciles accounting data from across your company’s systems (Stripe, banking, ERP, invoices, etc.) to give you a real time operating picture of your business\n* Automatically detects invoices and uploads journal entries to your ERP (and matching them with transactions from your bank)\n* Detects and automates tax obligations\n\nIf you’re struggling with late closes, disconnected systems, or finance workflows that rely on too many humans, Cranston gives you a single source of truth for your financial data. Our AI agents tie every number back to its real-world context so you can trust your books, stay compliant, and make faster, smarter decisions.\n\n# **Traction**\n\nIn the last 60 days, we’ve acquired our first customers and grown to $21.5K MRR. We have over a dozen customers using our technology to automate their back-office operations and save hundreds of manual hours entering \u0026 organizing information in their ERP. \n\n# **Our Team:**\n\nWe decided to start this company because we believe the accounting industry is on the cusp of massive disruption.\n\n**Max** previously ran a bootstrapped accounting firm that served thousands of clients and filed 10k+ tax returns. Former YC COO and debate champion. \n\n**Sean** did CS \u0026 AI at Stanford before dropping out to start ReMatter (Raised $20M+ from Founders Fund and Index Ventures), where he managed a team of 20+. Ex-Databricks and Ironman/Boston Marathon finisher.\n\nWe’ve been best friends for 5 years, and now we’re building the future of accounting together. \n\n# Asks:\n\n* Customer Connections: If you know a startup or SMB that’s drowning in back-office work, please refer them to us.\n* Connections to engineering talent: We need high-quality, dedicated engineers who understand business problems to help us build out our platform \n* Feedback on our vision: We are trying to build the future of accounting.
