Railz is a financial data API platform that helps fintech companies, lenders, and software businesses access normalized accounting and banking data from small and medium businesses. Founded in Toronto in 2020 and backed by notable fintech investors, Railz positions itself as the intelligent financial data layer for B2B financial services. The platform connects to major accounting software including QuickBooks, Xero, FreshBooks, Sage, Wave, and MYOB, as well as banking data via open banking connections. Railz normalizes disparate data formats into a consistent data model, eliminating custom parsing for each accounting system. Financial statements generation—income statement, balance sheet, cash flow statement—from raw accounting data is a core capability. Railz's Business Insights layer adds analytical context including financial health scores, industry benchmarks, and anomaly detection to raw financial data. This makes Railz particularly attractive for lenders and credit underwriters who need not just data access but financial analysis. The platform's read and write capabilities enable bidirectional data flow for reconciliation and automation use cases. Railz's AI-powered data enrichment categorizes and cleans transaction data automatically. The company serves embedded lending platforms, SMB-focused banks, and financial wellness applications. Railz's Canadian origin provides strong coverage of Canadian financial institutions and accounting platforms, complementing its North American and UK coverage.

Rutter is a universal API that provides fintech companies, lenders, and B2B software providers with a single integration to access commerce, accounting, and banking data from merchants and businesses. Founded in 2020 and backed by a16z, Rutter targets modern fintech builders who need to read and write financial data across multiple platforms without building and maintaining individual integrations. Rutter Commerce supports e-commerce platforms including Shopify, WooCommerce, BigCommerce, Amazon, eBay, and Etsy—normalizing sales, orders, products, and customer data. Rutter Accounting covers QuickBooks, Xero, NetSuite, and Sage with read/write capabilities for invoices, bills, accounts, and transactions. Rutter Banking provides bank account access via Plaid and direct connections. The platform's write capabilities—the ability to push data back into accounting systems—differentiate Rutter from read-only aggregators. This enables use cases like automatic ledger entry creation, invoice syncing, and payment reconciliation. Rutter is popular with embedded lending companies that need merchant GMV data for underwriting, accounting automation platforms that sync transactions, and commercial cards that need to post expenses. Its Sandbox environment provides comprehensive testing coverage. Rutter's modern API design, competitive pricing, and fast support response have made it a preferred choice among YC companies and a16z-backed fintechs building the next generation of financial products.
