# FullSeam

> FullSeam is an AI accounting platform that automates the close, reconciliations, and reporting on top of your existing ERP, for corporate accounting teams at fast-growing companies.

FullSeam makes your ERP AI-native without replacing it. It runs on top of QuickBooks Online, NetSuite, Oracle Fusion Cloud ERP, SAP, Sage, Microsoft Dynamics 365, Workday, Xero, Acumatica, and Infor, with no migration. Teams can be live the same day.

What FullSeam does:

- Close management: automates account reconciliations, workpapers, and journal entries, and routes each one to a reviewer.
- Custom agents: describe the work in plain English and FullSeam turns it into an agent that runs on your data, with review steps and an audit trail.
- Cash application and reconciliation: applies incoming payments to open invoices, including partials and splits, and reconciles the ledger against bank, card, and subledger data.
- Custom reporting: builds reports from live ledger data, with charts, filters, and a workbook behind every number.
- MCP server: lets teams use Claude and ChatGPT on their own close data.

FullSeam is SOC 2 Type 2 and HIPAA compliant, and customers have passed SOC 1 audits with FullSeam in their close. It was founded in 2025 by Tom Dowling, Aaron Coppa, and Geoff Segal, is backed by Y Combinator (Winter 2026), and is based in San Francisco and Chicago.
